In the world of search engines, none is bigger or more widely used than Google. While others pursue a share of the popular search market, the truth is that a lot of the smaller search engines share databases with Google. So once you're indexed on Google, you'll automatically be indexed elsewhere.
For most people, search engines are their principal gateway to the online world. Without a search engine, most users wouldn't have the slightest idea of how to find anything online, let alone you and your new book.
Search engines use what's commonly known as “spiders.” These “spiders” are sent to “crawl” your website, by reading text, checking links, and gauging your content for indexing. It's from this spider crawl that your ranking will be determined.
One of the things “spiders” are looking for when “crawling” through your website is your “keyword frequency.” Keyword frequency is just what it sounds like; it's the number of times your target keywords appear in your text, title, and links. So, there’s a formulated method to a spider crawl, as well as an optimum preference in what they are looking for.
In addition to keywords, other elements factor into a determination of ranking. One element is a link’s popularity. This “popularity” is based on the number of relevant inbound links to your website from outside sources. In this instance, more is always better. In addition, the quality of the relevant links from other indexed sites will not only improve your rank, but also ensure valuable, quality referrals.
Make regular updates to your website. By posting fresh, topical content that seekers are actively searching for, you'll trigger regular “spider” revisits that will improve your ranking. At the same time you'll be creating new posts that will be interesting and attractive to your readers and cause them to return regularly to your website.
With search engines, you need to be ranked as highly as possible. Statistics indicate that if you're not listed naturally on the first page of the search results, you will miss most of the new traffic attempting to find you. If you're not on the first pages, you will really be just lost in the crowd.
