I have spend a great deal of time working on my sites and never worried much about it.
Until last night I read this blog post:
I assume he had scrapper sites or 3-4 page KW related sites. That didn't bother me - it was the fact that he said he had friends who had manual reviews of their sites and lost their Adsense accounts, eventhough they had 40+ page sites.
I know people can have 40 pages of crap and poorly written content... but this post unnerved me specifically because of him mentioning the manual review.
I have taken a long time to carefully build out my sites to at least 20-50 pages, with original, useful content and plan to make them into 100+ pages and authority sites. But this post has me wondering why his friends got their accounts banned/sites de-indexed (I know no one can answer that specifically though).
Im worried when I hit a certain income $100+, that I'll get a manual review and am not sure what they look for that could get me into trouble...
I've worked really hard to build very useful sites and am just worried I guess...
