Hello Dears
Just follow these simple and natural tacts to avoid being banned by Google. I created these myself and also reviewed by my friends.
Add the following things to your site:
Privacy Policy, Terms and Conditions (Privacy Statement, Confidentiality, Log Files, Cookies, Links to this website, Links from this website etc)
If you want to save your site, make changes in it for some days... I mean update it. Create section "My Researches" or "My Blog" Put articles about your business. As much unique articles you can put.. But post as soon as possible. Google will not penalize those sites having lot of contents.
Mainly Google is banning those sites having very low amount of contents and lot of search Optimization. So Don't be late.
Best Regards,
