I know it's very very difficult to survive without Google as it comprises a majority share of the search engine market, but I believe we have come to depend on Google far too much. I have read many case studies detailing how Google has destroyed whole online businesses (I will paste the link if I can find it) - I hope these stories are not true, but I have to admit, it's pretty scarey to think that you could have a very profitable business one day and the next day, it is gone.
Also, a competitor once reported a site of mine informing Google that the site was dangerous to users. They placed a bright red and yellow warning sign on my URL for days and I know for sure that this had a huge and negative impact on my visitors and potential clients. I had to make an appeal to get it removed. In the end, there was nothing suspicious...
Just be careful and try to stay up to date with Google's T&Cs and code of conduct and we will see what happens in the future. (sorry if i strayed from the subject a little).
