If you are a responsible person then its your responsibility to accept your mistakes . Many people face problems in life by committing some mistakes . Successful person and responsible person will always accept his mistakes. In front of people there comes only three options for the mistake done by them .
1. He can avoid it .
2. He refuse to accept that he has committed any mistake .
3. He accepts it and never repeat it again.
Accepting the third option needs some courage . Only successful and responsible person accepts the mistake with patience . When situation goes out of hands negative people always has the sayings that it is done by that person and generally they blame each other .
Once President of a company was going to get retire . He was rich , famous , successful and had fulfilled his all money making opportunities. He presented two envelopes to the new president and said if you indulge in any crisis and you find no way to solve it , then for the first crisis open first envelope and for second crisis open second envelope .
After a few years a big crisis came in front of the new president , he remembered that now was the time to open the first envelope . In first envelope it was written that put all the blame to the old president . He exactly did that . After a few years again a big crisis came in front of him and he thought of opening the second envelope . He opened it and in it was written that it is perfect time for you to prepare same two envelope for the new president .
What was the moral of the story ?...
The moral was that we are never ready to accept our mistakes and we blame it to others .

How do we define SUCCESS ?
If you really want to get success , then make a habit of doing those things which unsuccessful people do not want to do .
A lot of research is been done between success and failure . The secret to success can be determined by reading the biography of the successful person . Those who are successful people they all have some similar qualities , because success always leave its mark behind . If we analyse the qualities of a successful people and apply in our own life , we will surely be successful someday. Likewise , unsuccessful people also have some common qualities which we can neglect from our life .
Success is nothing but continuous application of some standard values in your life.
Similarly not achieving success is just the continuous repetition of some mistakes of the past.
Some good writer truly said, "Achieving value based target is success" .
Its just the subjective feeling which comes from inside. Success is not earning quick , easy , free money but it is just to reach highest point and to earn respect from each individual.
To successful people there is one beautiful saying which goes like this : " Successful people don't do different things , they do things differently " .......

How to choose good Keywords for the SEO
Keywords are the terms and phrases that your target market uses when searching the major search engines and directories for the products and services you sell. Your keywords are used in everything you do and are the key determining factor in how you rank in the search results among many of the major search engines.
A critical step in natural search engine optimization is to select the right keywords for your business, products, or services (including descriptive words), and your target market. Understand whom you are targeting and build your search engine optimization efforts around your audience.
You need to choose keyword phrases that are going to bring sustainable targeted traffic consisting of potential customers—not just anything and everything. What you may think is the perfect keyword phrase may not be used at all by your target market in their search queries, which is why it is so critical to research and validate your keywords.
Ideally, each page of your Web site is going to focus on a different set of keywords that are specific to the content at hand. If you were to focus on the same set of keywords on every page, then you would hit only one small portion of your market potential because you are only going to hit those same keywords over and over again—it is self-defeating.
First, you want to gather a master list of all possible keyword phrases. To make the data easier to manage, you can create different keyword list profiles that represent individual topics as opposed to trying to cover all topics in a giant master list. For example, if you have two product lines, you can create a keyword list for each. Naturally, some keywords are shared across the lists, but it is important to understand that the people looking for one topic (for instance, “jobs”) are not necessarily the same people looking for another topic (let’s say, “trucks”), and as such they are going to use different keyword combinations in their searches.
How do you create your master keyword list? Here are four solid techniques
for generating a list of potential keyword phrases:
1. Brainstorm, survey, and review promotional material.
2. Review competing and industry-leading Web sites.
3. Assess your Web site traffic logs.
4. Use keyword suggestion and evaluation tools.
Be sure to record the keywords you gather in a text document in your wordprocessing
program or in a spreadsheet. Including them in a spreadsheet or database makes them much easier to sort when it comes time to prioritize the keywords and weed out the junk.
As you work your way through the list of techniques, you want to cycle back to some of the techniques because you will come across search terms that can expand the scope of your original efforts and open the door to new, more targeted phrases that you might have missed the first time around.

Learn the Search Engine Ranking Criteria
Each search engine has its own unique ranking criteria and its own unique algorithm, or formula, giving different weighting to each of the criteria in its formula. For the search engines that you have decided to focus on, you have to learn as much as you can about their ranking criteria and relative weighting.
The site with the highest score appears at the top of the results and the rest appear in descending order of their score. The search engines are all fighting for market share. The more market share a search engine has, the more valuable the company is. To gain market share, a search engine has to provide better results than its competition. It is for this reason that the search engines are changing and improving their formulas on an ongoing basis. You have to keep up with changes in these formulas, tweak your site accordingly, and resubmit when necessary.
The search engines use different databases for their search results. They
have different algorithms or formulas for their ranking. They have different
weighting for the various elements within their formula. They change their formulas
over time and they change their ranking over time. Sound complicated?
Things have changed quite a bit from the early days. Elements that used to
have significant weighting may now have very little weight. You have to remember
that it is the highest total score you are looking for, so even if an element
has reduced weighting, if the element has any points at all you want to
incorporate that element to maximize your total score. Sometimes the top sites
are within a small number of points of each other.
It is not as daunting as it might sound, because the major search engines
tend to look at similar information but weight the relevancy for particular items
differently in their algorithms. That having been said, here are the most important
areas on a Web page that you must address when performing organic search
engine optimization:
• Title tags (page titles)
• Keyword meta-tags
• Description meta-tags
• Alt tags
• Hypertext links (e.g., anchor text)
• Domain names and file names
• Body text (beginning, middle, and end of page copy)
• Headers
• Between the “NOFRAMES” tag of framed Web sites.
Page titles and text-based page content are the most important of the noted placement areas. Keyword meta-tags are not as critical as they once were, but
are still applicable for some engines. Remember—it is the absolute highest score
you are looking for; if there are any points available, you want to design your
site to take advantage of them.
Because Google is the favorite search engine for the time being, let’s take a
closer look at how it ranks pages. Google uses its internal index for its primary
search listings. Google has many other features as well, some of which include:
• An images search
• Usenet news database
• A news search feature
• Froogle (a shopping search tool)
• A local search
• A blog search
• A video search
• A product search
• A directory search
• A catalog search
• Advertising services through the Google AdWords programs.
The ranking formula for Google’s main search function looks for the keywords
in the visible body text, header tags, title tags, hypertext links, and Alt
tags. Google gives a very heavy weighting to the link popularity, with extra
points for quality of links and relevancy of text around the links. Google also has miscellaneous points available for such things as:
• Age of domain/site—The longer your domain name has been registered,
the more likely you are serious about being online for the long term.
• File size—Try not to exceed 100k. A recent study found that the body
section of your site ranks best between 50 and 70k in size. More than
100k in size might not be cached unless it is considered exceptional
content.
• Freshness of content—Google is always looking for sites that are updated
on a regular basis. The more frequent you update your site, the
more frequent Google’s spiders will visit your site.
• Links from directories—Google awards points if directories such as
Yahoo!, Looksmart, DMOZ, and About provide a link to your site.
Most of the search engines are giving heavy weighting to link popularity—
that is, the number of links to your site from other sites on the Internet. The
search engines are getting very sophisticated in the weighting of link popularity,
with the search engines giving extra points for link relevancy—that is, how high
the site with the link to your site would rank for the same keyword. Other
points are awarded based on the keywords in the text around the link pointing
to your Web site.

What Is SOCIAL BOOKMARKING ?
Social bookmarking allows users to store links to Web pages, otherwise known as bookmarks, that they find useful.
Rather than saving these bookmarks on your computer, as was normally done through the “Favorites” button on your Internet browser toolbar, these new social bookmarking sites allow users to save their bookmarks to a Web page.
They allow users to save their favorite articles, blogs, music, reviews, RSS feeds, and more and allow users to access them from any computer on the Web.
To create a collection of social bookmarks, you must register with a social bookmarking site—and there are many from which to choose.
Once you have registered, you will be able to store bookmarks, share them, and categorize them with the use of keywords or tags.
These sites allow users to search for other Internet bookmarks saved by others and add them to their own collection and subscribe to the lists of others.
Social bookmarking has created a new way for Web site visitors to organize and categorize information and resources.
They represent the user’s personal library and when combined with other personal libraries, they allow for many social networking opportunities

But truth is they have every ingredient inside them to become successful.
Success is what lies beneath you , not how you look or what you are.......
Many people lose their hope because they have their personal problems that people like women's , children , black , physical disabled people don't deserve to be successful.
I would like to tell you a story of a poor man , who lived in a village , earned his living by selling helium filled balloons. He daily came to city to sell his balloons for his living.
When he saw that his balloons sale was getting low , he threw one of the balloons in air . Because of helium inside the balloon went up . Seeing this children got attracted towards it and they purchased his balloons. Whenever this thing happened , he just let away one balloon in the sky. One day when he did this thing , a boy came to him and asked , " Is the samething will happen if you threw black balloon in the air ". Seeing the little boy innocence , he gave him the black balloon and told him that ..... It is not the color , structure , physical appearance that is responsible for the fly away of balloon , it is what is inside (helium gas) that makes it fly high.
What was the moral of the story ?.
The moral of the story is , : everything is inside us which will make us rise high . So believe me success and failure all depends what you think , do , apply etc.........

How Does RSS Work ?
What is RSS ?
One of the earliest forms of content syndication is the Dear Abby column.
As most of you know, Dear Abby writes one column and it appears, or is syndicated,
in many different publications.
That was the “old school” way; today we have RSS readers and feeders.
RSS is an acronym for Really Simple Syndication.
RSS is a format for syndicating news and other content that can be
broken down into discrete items.
RSS is really a delivery channel that allows you to send content to subscribers and also to other Web sites.
Once information is in RSS format on a site, an RSS reader can check the feed for updates
and react to the updates in a predefined way.
RSS can deliver many different types of content including text, audio, or video files and can distribute them quickly and easily.
How does RSS work ?
To publish your promotional material and make it available to the masses for their review or publication on their Web site, you first need to create an RSS feed.
To do this you need to develop an XML file structured in the proper format, upload it to your server, and then provide a link to that file on your Web site.
There are many tools online that make this an easy process.
There are RSS software programs that enable the user to quickly and easily create and
publish syndicated content.
Once you have your RSS feed developed, you need to develop your content and update it on a
regular basis; be sure to include a catchy headline and a link to your site in your content.
Usually you will provide a summary letting the subscribers to your feed know about the new content, with a link directly to it.
Alternatively, you could provide the full content in your feed. Your subscribers need an RSS news reader or news aggregator that will enable them to access and display the RSS content.
There are many different RSS readers and news aggregators available for free.
You might want to provide a little education to your visitors as some may be new to RSS, and also provide links to recommended RSS readers from your site to enable new users easy access .
The news aggregator helps viewers keep up with all their favorite resources by checking their RSS feed and displaying the new or recent items from each of them.
There are also Web-based RSS services that work with your browser.
After you run through your initial setup, you subscribe to any RSS service you want to access on a regular basis.
The RSS readers automatically retrieve updates from sites that are subscribed to, providing the user with the latest content as it is published.
Benifits of RSS ...
The benefits of RSS are many:
1. You are guaranteed 100 percent delivery. Spam filters are not an issue. This means that your marketing and other messages to customers and potential customers are getting through.
2. You can quickly and easily get exposure on other sites that have the same target market you do by having your content published on those sites through content syndication. You immediately increase your reach.
3. Through your RSS feed opportunity, you can build your targeted database.
4. You can improve your search engine ranking through providing keyword- rich content that is distributed to other sites with the link back to your site.
5. You will increase targeted traffic to your site.
6. You will increase your brand awareness.
7. Through distribution of great content, you can establish yourself as a great resource.
8. You have a great potential to increase revenue through your use of RSS with the delivery of coupons, specials, and promotions with the links back to your site.
9. You don’t have to worry about compliance with legislation, privacy policies, spam, or age guidelines.
10. You will build trust, your reputation, and credibility.
11. RSS feeds are significantly less work than maintaining and promoting through private mail lists. You don’t have to worry about cleaning lists, running your content through the spam checker, or removing bad e-mail addresses. This does not mean that you should switch everything previously provided through permission-based e-mail to RSS.
12. RSS content is seeing significant click-through rates.

Methodology to Make Your Site Search Engine Friendly
When Internet users are looking for a particular product, service, subject,
or information pertaining to an area of interest to them, how do they do it?
The most common research tool used is the search engine—85 percent of
people doing research online use search engines to find what they are looking
for. Because search engines can bring significant volumes of traffic to your
site, you must understand how the major search engines work and how the
design of your site can influence the indexing of your site by the search engines.
You must also know about the elements that are included in the search
engines’ algorithms, or formulas, that are outside your Web site and what
you can do to ensure that you earn maximum points for those things you can
influence.
When people conduct Internet searches, they rarely go beyond the first
couple pages of results. If you want to be noticed, you need to appear in the
top 10 or 15 search results—ideally, you want to appear on the top half of the
front page of search results. But before you submit to the search engines, you
have to be sure your site has been designed to be search engine friendly.
To make your site search engine friendly, you have to:
• Decide which search engines are critical for your success.
• Learn as much as you can about their ranking criteria and the weighting
given to each criterion in their algorithm. It is also important to know
which databases they are using.
Then you must:
• Determine the keywords that your target market is using in the search
engines to find what you have to offer,
• Assign those keywords to specific pages throughout your site, and then
• Populate the pages with the assigned keywords in the appropriate places
given the ranking criteria for your targeted search engines.

Basic Idea Behind Popularity Ranking
The basic idea of "popularity ranking" (also called prestige ranking) is to find pages that are popular , and to rank them higher than other pages that contain the specified keywords. Since most searches are intended to find information from popular pages, ranking such pages higher is generally good idea. For instance , the term "google" may occur in vast numbers of pages, but the page google.com is the most popular among the pages that contain the term "google". The page google.com should therefore be ranked as the most relevant answer to a query consisting of the term "google".
Traditional measures of relevance of a page such as the TF-IDF based measures, can be combined with the popularity of the page to get an overall measure of the relevance of the page to the query. Pages with the highest overall relevance value are returned as the top answers to a query.
This raises the question of how to define and how to find the popularity of a page. One way would be to find how many times a page is accessed and use the number as a measure of the sites popularity. However, getting such information is impossible without the cooperation of the site, and is infeasible for a Web-search engine to implement.
A very effective alternative is to use hyperlinks to a page as a measure of its popularity. Many people have bookmark files that contain links to sites that they use frequently. Sites that appear in a large number of bookmark files can be inferred to very popular sites. Bookmark files are usually stored privately and not accessible on the web. However, many users do maintain Web pages with links to their favorite Web pages. Many Web sites also have links to other related sites, which can also be infer the popularity of the linked sites. A Web search engine can fetch Web pages(by a process called crawling) and analyze them to find links between the pages.
A first solution to estimating the popularity of a page is to use the number of pages that link to the page as a measure of its popularity. However, this by itself has the drawback that may sites have a large number of useful pages, yet external links often point to the root page of the site. The root page in turn has links to other pages in the site. These other pages would then be wrongly inferred to be not very popular, and would have a low ranking when answering a queries.

What is Search Engine Spamming
Search Engine Spamming refers to the practice of creating Web pages, or sets of Web pages, designed to get a high relevance rank for some queries , even though the sites are not actually popular sites.
For example, a travel site may want to be ranked high for queries with keyword "Travel". It can get high TF-IDF scores by repeating the word "Travel" many times in its page.
( Repeated words in a web page may confuse users; spammers can tackle this problem by delivering different pages to search engines than to other users, for the same URL , or by making the repeated words invisible , for example by formatting the words in small white font on a white background.)
Even a site unrelated to travel, such as a pornographic site, could do the same thing, and would get highly ranked for a query on the word travel. In fact, this sort of spamming of TF-IDF was common in early days of Web Search, and there was a constant battle between such sites and search engines that tried to detect spamming and deny them a high ranking.
Popularity ranking schemes such as PageRank make the job of search engine spamming more difficult , since just repeating words to get a high TF-IDF score was no longer sufficient. However , even these techniques can be spammed , by creating a collection of Web pages that point to each other, increasing their popularity rank.
Techniques such as using sites instead of pages as the unit of ranking( with appropriately normalized jump probablities ) have been proposed to avoid some spamming techniques , but are not fully effective against other spamming techniques. The war between search engine spammers and the search engines continues even today.
The hubs and authorities approach of the HITS algorithm is more susceptible to spamming. A spammer can create a Web page containing links to good authorities on a topic , and gains a high hub score as a result.
For example, a travel site may want to be ranked high for queries with keyword "Travel". It can get high TF-IDF scores by repeating the word "Travel" many times in its page.
( Repeated words in a web page may confuse users; spammers can tackle this problem by delivering different pages to search engines than to other users, for the same URL , or by making the repeated words invisible , for example by formatting the words in small white font on a white background.)
Even a site unrelated to travel, such as a pornographic site, could do the same thing, and would get highly ranked for a query on the word travel. In fact, this sort of spamming of TF-IDF was common in early days of Web Search, and there was a constant battle between such sites and search engines that tried to detect spamming and deny them a high ranking.
Popularity ranking schemes such as PageRank make the job of search engine spamming more difficult , since just repeating words to get a high TF-IDF score was no longer sufficient. However , even these techniques can be spammed , by creating a collection of Web pages that point to each other, increasing their popularity rank.
Techniques such as using sites instead of pages as the unit of ranking( with appropriately normalized jump probablities ) have been proposed to avoid some spamming techniques , but are not fully effective against other spamming techniques. The war between search engine spammers and the search engines continues even today.
