Organic seo overview
You first need to understand search engines,and how they work. First of all, let me begin by defining a searchengine. You may be familiar with Google, Inc. - the most prevelantsearch engine at the time of this writing. There are other searchengines that have worn the crown in the past, including AltaVista andInktomi to name a few.
A search engine is typically in the form of a web site thatprovides the visitor with an HTML form to fill out, which then searchesthe search engine's database of content. With Google's web site, youcan enter specific "keywords" into the form, and it will find allrelevant web pages on the internet that contain those search terms youentered. For example, if I search for "horse veterinarians" I wouldexpect the results to be web pages which have the words "horse" and"veterinarians" in them. Of course there is a ranking order appliedthrough a search engine's algorithm to determine which site is the mostrelevant.
Search engines, for the most part, all work the same way. A searchengine company operates what is called a "spider" - an automatedprogram that "crawls" the Internet looking for web sites. The spiderthen reads the content on those web pages it finds, and classifies itand assigns value to that page in terms of backlinks. In Google's case, it assigns what's called a PageRank© (more on this later).
A deep crawl is when a spider, for example Googlebot, crawls the entire web site. The first time a site is encountered by Googlebot, it only indexesthe first page. It can be up to 1 full month before Googlebot comesback to the site and does a deep crawl, indexing every page that isinterlinked on a web site. Patience is a virtue with SEO, asimprovements are not seen overnight.
