In the past 6 - 8 months I have been reading webmaster site after webmaster site, blog after blog on the sandbox effect. People with anything from a few pages on their site to sites with over 100,000 pages not appearing in Google. For every one complaint their must be ten that don't complain. Googles sandbox must effect millions of pages. That is an awful lot of pages that aren't earning revenue for Google, over a six to nine month period, and from what I read all the pages still eventually make it into Google. For no end benefit at all. Further to that they are mainly high volume keywords that are in the sandbox which further effects their revenue. If I was an investor I would not be happy with Google.
