Is there such a thing as too much content?

I would say that 5 good pages are better than 1 great page.

 

Google stops indexing pages after too much text.

 

Though a bot may scan an entire html page, it makes up its mind around the first 300 words. The assumption is, for any article to be of value to the reader, the writer would make the theme clear in the introductory and perliminary sentences. SEs factor semantics and natural writing values into their algos.
