Co-citation and co-occurrence are important factors that influence the position of your web pages in Google’s search results. The environment in which the links to your website can be found have a big impact on the value of the links.
1. Co-occurrence: the words on the linking pages influence your rankings
Even if the link to your website does not include your targeted keyword, your web page can get a ranking boost for that keyword. The link just has to come from a page that is related to the keyword.For example, if a web page has an article about shoes, boots, sneakers and sandals, then your website will get a ranking boost for these keywords if that page links to your site.For example, the following link has a positive influence on the ranked pages for the term “shoes” although it is not included in the link text:
How to find websites that contain the right keywords:A backlinks tool will help you to find websites that contain your keywords in the title and in other page elements. Links from these web pages will increase the position of your own web pages for these keywords.
2. Co-citation: the other links on the linking pages influence your rankings
Suppose your website is about selling shoes. If your site is linked by other websites that link to your website and other websites that are about frogs and toads then Google might think that your website is related to frogs and toads.It’s important that the other links on the web page that links to you are related to your site. If you’re listed in the “shoes” category of an Internet directory then all web sites in the same category are usually also about shoes.If web sites 1, 2, 3 and 4 all link to the web sites A, B, C and D. Although A, B, C and D don’t link to each other, Google thinks that A, B, C and D are related to each other because the same web sites link to them:
Even though they don’t directly link to each other, websites A, B, C and D are related. The more web sites they are linked from, the stronger the relationship.
The whole point of co-citation is to associate keywords and topics with the links on a page. Even if the link to your website uses ‘click here’, Google will be able to find out what the link is about if it comes from the right page.
