Useful Information about SEO

1.Page Rank works by counting the number and quality of links to a page to determine a rough estimate of how important the website is. The underlying assumption is that more important websites are likely to receive more links from other websites.

2. The Panda update was designed to improve the user experience by catching and demoting low-quality sites that did not provide useful original content or otherwise add much value. At the same time, it provided better rankings for high-quality sites—sites with original content and information such as research, in-depth reports, thoughtful analysis and so on.

3. Cloaking: In this practice a website shows different information to search engine crawlers than users. For example, a spammer might put the words “Sony Television” on his site in white text on a white background, even though the page is actually an advertisement for Viagra.

4. Keyword Stuffing: In this practice a website packs a page full of keywords over and over again to try and get a search engine to think the page is especially relevant for that topic. Long ago, this could mean simply repeating a phrase like “tax preparation advice” hundreds of times at the bottom of a site selling used cars, but today spammers have gotten more sophisticated.

5. Paid Links: In this practice one website pays another website to link to his site in hopes it will improve rankings based on Page Rank. Page Rank looks at links to try and determine the authoritativeness of a site.

6. Alt Tag : 16 Words are allowed by Google in Image alt tag.
