How Search Results Are Ranked

 How Search Results Are Ranked.What are the factors that affect search rankings As a web marketer, you care less about how Google or Yahoo! searches the Web than you do about how high up you appear in that search engine’s results pages. What makes a search engine rank a particular site high in its search results and a similar site much lower?

Each search engine has its own particular algorithm for ranking the pages in its search index.In general, though, they follow similar methodology; similar factors are important to all the major search engines.

Accordingly, the following three points are important : Text analysis, Links and link text, PageRank


To that end, it’s instructional to look at how Google, the Web’s largest and most popular search engine, ranks its results.

Google, like all the other search engines, attempts to serve its users by ranking the most important or relevant pages listed first and ranking less-relevant pages lower in the results.

((Sites' positions in our search results are determined based on a number of factors designed to provide end-users with helpful, accurate search results. These factors are explained in more detail at http://www.google.com/corporate/tech.html.
In general, webmasters can improve the rank of their sites by increasing the number of high-quality sites that link to their pages.

  • Search engines can distinguish between pages that match your search topic. 
But how, and what basic standards ? How does Google determine which web pages are the best match to a given query?

While Google keeps its precise methodology under lock and key, for competitive reasons, we do know that there are three primary components to its results rankings:
  • Text analysis—Google looks not only for matching words on a web page, but also for how those words are used. That means examining font size, usage, proximity, and more than a hundred other factors to help determine relevance. Google also analyzes the content of neighboring pages on the same website to ensure that the selected page is the best match.
  • Links and link text—Google then looks at the links (and the text for those links) on the web page, making sure that they link to pages that are relevant to the searcher’s query.
  • PageRank—Finally, Google relies on its own proprietary PageRank technology to give an objective measurement of web page importance and popularity. PageRank determines a page’s importance by counting the number of other pages that link to that page. The more pages that link to a page, the higher that page’s PageRank—and the higher it will appear in the search results.
The theory behind PageRank is that the more popular a page is, the higher that page’s ultimate value. While this sounds a little like a popularity contest (and it is), it’s surprising how often this approach delivers high-quality results.

The precise formula used by PageRank (called the PageRank Algorithm) is a tightly held secret, but we do know that it’s calculated using a combination of the quantity and quality of inbound links.

That is, the number of inbound links you receive matter, but it’s also important which pages are linking to your site.

You see, Google figures that links from pages more closely related to your page’s topic should mean more than random links from unrelated pages.

So, for example, if you’re marketing hospital supplies, a link from a hospital website would result in a higher rank than a link from a site about minorleague baseball.

With this in mind, it’s likely that a page with fewer, higherranked pages linking to it will have a higher PageRank than a similar page with more (but lower-ranked) pages linking to it.
