I’ve been running some little experiments by adding more and more internal links on a page to see if it has a negative effect on Google rankings.
This page on one of my other sites ranks high in Google for Free Advertising
It had approximately 30 internal links on the page which I decided to increase as part of the experiment.
It now has closer to 1,700 links on the page and still ranks high.
I’ll leave it like this for a month and monitor rankings, but at the moment adding over 1,500 links appears to have had no detrimental effect.
Time will tell.
Please feel free to comment below if you want to to keep updated on this test.
