Back To Basics – How and Why Google Spiders Crawl Websites!

For the most part, creating a website is easy; It is getting recognized by Google in the search results that is difficult. SEO consultants spend time trying to make a website easier for Google’s indexers to notice, all as a part of the best SEO effort possible. Despite this, many website owners do not understand how web crawlers work to index a website and why getting good optimization results – even when working with SEO expert services – can be so challenging. By understanding how Google works, you can gain a new appreciation for SEO efforts, and how important it is for a website to be seen by web spiders.

What Are Web Spiders?

Contrary to some perceptions, there are no eight-legged arachnids employed by Google; however, its search engines do “crawl” in their own way. Google’s search engines consist of huge amounts of complex web code, essentially making Google little more than a very massive program of its own. The best SEO consultants say what this program does is visit every linked website, one by one, looking for data. Because the process is slow, and there are many systems working on this at the same time, the process crawls along from one page to another following links and collecting data – especially new pages, or changes to already recognized pages.

What Is Indexing and How Does It Happen?

After web pages are crawled, those who offer SEO expertise say Google’s servers take screen shots of those pages and create a cache of them. Cached pages are then indexed or stored. It is these pages that Google uses to determine the value of a web page in comparison to other similar pages. Since indexing only occurs to cached pages, it means changes made to web pages are not immediately detected – and new pages are not recognized until they are crawled and cached again.

How Often Are Pages Indexed?

There is no definite answer to how often Google crawls and indexes websites, as the process is ongoing; however, there are ways to speed up page indexing. While crawling, web spiders determine if there is any new content on a page, then cache and re-index all pages, both old and news. So, while there is no way to know for sure how often indexing occurs, the best way to ensure a website is re-indexed often for optimal SEO results is to keep adding new content. When new content is added, it is reasonable to expect that a page will be indexed within a few days.

Why Do All Types of Links Matter?

From simple navigation to building strong incoming links, experienced SEO consultants point out that links are very important for faster crawling and indexing as well as to be more easily recognized as a page with value that deserves to be ranked. Web crawlers travel along linked pages, so providing the simplest, most straightforward way for a page to be found on a website is best. Fewer levels of links, plus the addition of a sitemap, is recommended. Having good, incoming links attracts spiders who are crawling other sites, making a valuable connection between the two. All of this helps create faster, better indexing, and better optimization results.

While this is just a brief explanation of Google’s function, these are a few areas of importance that website owners should know. Where web crawling and site indexing is concerned, the way to build the best SEO and earn good page rank is by having a website that is easily crawled, updated frequently, and contains strong incoming links. These ideas, along with the efforts of SEO consultants using SEO expert services to implement other recommended techniques for generating good optimization, are the best ways for a website get to the top of the search engine results pages!
