Is there any specific amount of links-per-page that shouldnt be passed in order to allow Google to follow all of them? I need to make large site's index and I need to separate links per page so that I eventually fit to these number.
They say only 100, but they will get much more than that. You'll have better results if you stay around 100 or less.
Is there any practical proof that Google wont follow links if they are on a page with lets say 300 other links?
Been very curious about the same issue and so am running a test that I am logging publicly .... http://www.seopark.com/forums/viewtopic-178
before the pr went down on one of my clients sites we had a sitemap which has around 400 links on it to products and they were all indexed withen a week. Heres the Sitemap: Heath Diesel
Why does google only recommend 100/page then? Does the number of links it follows depend on the number of inbound links to that page? I have pages with ~100 links on it, but I try to keep around or under 100 not only for navigational sake, but for fear google will hate. But I also see sites that sell sports team products and list every conceivable team (ncaa, nba, nfl, nhl, etc) onto each page of their site via drop down and they rank very well for those terms.
If you look closely, Google's recommendation of 100 links per page is in their Design and Content Guidelines, not the Technical Guidelines. The design guidelines are just general guidelines for designing a good site for users. For example, "Create a useful, information-rich site and write pages that clearly and accurately describe your content.". If you choose to not adhere to that, you still will be spidered.
Google recommends that you keep the links (inbound and outbound) to about 100. But consider a site map that has 5000 links on it and is indexed. The real issue is that a page with over 100 links on it looks bad. So many of now use CSS navigation or list boxes with links in it to overcome this. And then use a XML Site map and HTML Sitemap for submission.
