Who would have thought that your links would lose value as time goes on. Well it does happen, just look at your press releases and your articles for distribution, ok well its obvious that those are going to lose value, right? But what about those one way links or linking partners you may have. How do those lose value? There is no real “quick” answer as to how or why they do, at this point, it’s just a theory.
I know some of you are probably asking yourself well how did you come up with this theory, well besides the countless SEO’s that have noticed this trend, it has also been a part of my site optimization experience that some links lose their value over time. So how do the links diminish in value?
Site/Page has not been updated in x amount of days
- If a site is only updated once a month there is a good chance that Google and the other Search Engines will not visit that site very often; maybe once a month to once every two to three months. If you have a link on that site, it is not necessarily in your benefit to have the site spidered so infrequently. Although every time the search engines spider the site, they see your link and it passes value, but since they come by so rarely, the link slowly begins to lose value. If the owner of the site where your link sits then moves to only updating the site once every few months your link will get even weaker.
If this was a link partnership you had with the site and your site gets crawled once a week while his only gets crawled once every couple months you are passing a lot more value to him then he is to you. It might be time to remove his link from your site and forget about the one you get back from him.
This is something else that we have talked about before when looking for link partners or one way links. You want to make sure that the site has been cached within a month. Also check the bottom or around the site for a copyright date. I like to recommend that the site copyright is not older than 2-3 years old. Occasionally, webmasters do forget to update the copyright so a 2-3 year difference is about the longest I would go.
