Ever wonder how Google decides which websites get ranked high in the Google index? The main objective of many websites is to get as many webpages as they can in the Google index so that the overall website will pop up high in search results.
Of course, in order to ever get to this point a website master first has to understand how Google decides how many pages from a website they should index for the website. Once you understand the basic formula it will be much easier to improve how many of your pages make it in as well.
Although it has not really ever been confirmed directly by Google, there is a supposed ‘indexation cap’ in place that limits how many pages Google will index for each particular cap. This is to help control the overabundance of information now available on the internet and simply to make their index more concise. If you are a small website this may not be much of a worry, but while cleaning out their index if you are a large website this could be potentially harmful if you get cleaned out. Thus, be aware of the fact that even a high index still needs to be properly maintained.
Here are the metrics that you really want to know about, the factors that help Google decide whether you are worth inclusion in their index or not. The first thing they will look at is the web link graph which helps them see how important your site is by how well it is linked to other websites that are deemed to be important.
Second, once Google finds links it will look to see where they came from and how diverse the domains are that the links are coming from. They will also look at your domain to see how trustworthy it is. At the same time, they will compare the growth or your website to the growth of your content. If your content is growing rapidly but your links are not this is a sign that you may not have worthy quality to direct users to.
