what does google what to say when they talked about "excessive" to control link scheme! Is there numbers on how many does SEO dp a link trade without violating the webmaster guideline's about excessive linking! any knowledge about this or a good article source!? thanks,
They wouldn't say, because then we could all have just slightly less than that... You know sites you've seen where there are more link pages than content pages, or pages and pages of links unrelated to the site topic, or 150 footer links, or pages with 50+ links on? That's the kind of thing to avoid the most. But they weren't links worth having anyway since they do so little benefit and are usually on uncached pages.
