How do search engines rank their results?
Every search engine has developed a formula for ranking web sites. Every search engine uses a different formula, which is why the results will be different between Google, Yahoo, Bing, Ask.com and other search engines. These formulas, known as algorithms, are constantly changing as the search engines try to achieve better results. The process of improving how your websites rank on the web is known as search engine optimization or SEO for short. The results obtained are always changing as different things get more popular or go out of fashion
How do you get higher up in the rankings?
There are many things you can do to achieve higher in the rankings, for example:
- Update your content regularly - this is important as it makes the information more relevant to the reader.
- Have a link-worthy site - focus on having clear, relevant links which use keywords rather than 'click here'.
- Use alt tags - they allow search engines to locate your page which is crucial.
Focus on making all the information relevant and always use alt tags.
Indexes and Spiders
Google indexes list all of the webpage that google knows about. To do this, google uses something called spiders. Spiders are software programs. They start by getting a few webpages by asking various questions - does that webpage contain the words you've typed into the search engine? How often? Is it from a quality website? Does it contain the keywords in the title? Altogether, it can ask over 200 questions. After it has a few websites, the spiders follow the links on the pages and the links on those pages and so on, until they have indexed a large chunk of the web, a lot of which is relevant to what the searcher initially searched.
