How do Search Engines work?

Search engine companies like Google and Yahoo are all about finding content that will bring them more traffic (and thus more ad revenue). In other words, their results must be relevant and high quality. In the words of Nathan Buggia of Microsoft Live Search: “Our whole role in life is to find the best content on the web and bring it together with people who are looking for that content. And to do that, we’ve invented a couple of algorithms to figure out what people think is good content.” Here’s a simplistic explanation of how search engines work:
  1. Crawl - They send out ‘spiders’ or ‘robots’ that crawl your pages and send back details for processing.
  2. Index - They then use really complex mathematical algorithms to deduce the subject matter of your site from frequently used words and the text on links to, from, and within your site. This tells them which searches your pages are relevant to.
  3. Rank - They consider some 200 factors when ranking, but the most important – of those that you can actually manipulate – is the number of external links pointing to your site, where those links come from, and what anchor text is used in those links. If there are lots of links pointing to your site, all from quality sites, and all with relevant words in their anchor text, you’re likely to rank well. The logic is that if all those webmasters are willing to link to you and they’ve used a variety of relevant words in their links (i.e. they’re not automated links), your site must be relevant and important.

Meta Tagging is a great way to find keywords that are directly from your competitors. You want to look at your competitors meta tags in the source code of their website. Find who is getting the top search rankings on google for your particular niche and open up their HTML source code. Find the area called Meta Tags and look for a code line that says "meta name" and there you will find all the keywords your competitor is targeting.

that was a nice article , it has a great explanation about the SEO. SEO is an art of increasing the PR by applying the various methods, but keep in mind friends there are some SEO's who use the non ethical techniques to optimise their site in the search engines. Please don't think that the crawlers are fools, they know what you are doing so do well.
