Google once provided a guideline that said you should not have more than 100 links on a page. Many webmasters still strictly follow this rule.
However, Matt Cutts explained in January 2011 that this advice is about 8 years old, and Google have now actually removed this rule from their guidelines. The rule was initially set as in the early days of Google only a part of a page would be crawled, it was limtied to about 100kb. That is no longer the case.
But, for SEO purposes it may be better than most pages do have fewer links as this can concentrate (or funnel) pagerank.
