SEO stands for Search Engine Optimisation. Each search engine, Google, Yahoo, Bing etc. have their own secret criteria (algorithm) for ranking websites in search results. They change their algorithms from time to time without notice, but the following is a common sense list of factors used.
Once your website is listed on search engines you will wonder how to get it to page one of Google.
The following pages may help you understand how that can work. It’s really common sense, not magic. Think of how you look for information on a particular subject in a bookshop and how you select the book.
You may also be approached by many SEO experts offering to get you on page 1 of Google for a fee. Ask them how they will do that. They may not tell you.
