By this I mean, I am building a web devoted to a specific artist. My intro text is extensive - 600 to 700 words which revolve around this person...very informative. Below it, I intend to include a 728 wide leaderboard. Below that a table containing text describing "recommended reading" pertaining to artist in quiestion. Would it be advisable to include text hyperlinks of recomended reading on a SEPARATE page or on this index page? I also intend to include a Goog search box. In essence, is LESS BEST in that only including text pertaining to the topic or subject in question so those AdSense ads are more "targeted"?
Nope - content is always good - particularly if you're making a site for the benefit of the visitors instead of just to rake in AdSense revenue. More content = more keywords = more chance of an ad your visitors are actually interested in! That's my take anyway.
Perhaps you can break the content into multiple pages if amn article is overly long because I get the impression from having read here that people don't like too much content on a single page. However, the pages must be broken into pieces logically.
