How do search engines work?
Search engines use programs, often referred to as spiders, robots or crawlers, to search the internet. These programs are used by search engines to build an index of the internet. However, although most search engines will provide tips on how to improve your page ranking, the exact algorithms used are well guarded and change frequently to avoid misuse. But by following a few well accepted search engine optimisation (SEO) techniques you can ensure that your website is well indexed and remains high in the rankings.Different search engine methods
Each of the three main search engines use different methods to rank websites. Understanding these methods will help you understand the SEO strategies outlined in this guide.The three main search engines are:
- Google - Google's PageRank assesses the value of a webpage based on the number of backlinks ie links back to your website. Each link is counted as a vote, from one page to another. Google also analyses the content on the page that makes the link. Votes cast by pages that are themselves seen as important by Google weigh more heavily and increase the ranking of the linked pages.
- Yahoo! - Yahoo! began as a manually edited directory. It now uses link analysis tools to determine page relevancy, though content is also important in deciding search relevance. Other factors that are important include backlinks and a good site design.
- Bing - Microsoft's Bing search engine ranks websites based on the webpage content, the number and quality of websites that link to your pages, and the relevance of your website's content to keywords.
Optimise your site with better design
Some of the best search engine optimisation (SEO) results can be achieved by optimising site design and content to utilise the techniques used by search engines to index web pages. Good site design makes it easier for search engines to index your site, and increases your chances of a higher ranking in the results pages. Basic SEO techniques include:- site accessibility
- high quality content
- links to and from other websites
- use of relevant keywords
Make your site accessible
The most important part of making a website search-engine friendly is good design. Well-written, easy-to-navigate pages - with interesting information and well-designed e-commerce systems - will get repeat visitors as well as satisfied customers. You should consider the technologies to be used and whether they lend themselves to SEO. Although SEO can always be improved, it is harder to do so once the technology is in place and the website has already been built. If you use a content management system, you should make sure it produces SEO-friendly pages.Would you like some Website promotion or SEO work done? Check out: http://promotion.highersitesgroup.com/
