This is an question we all should think about if we are continuing to grow our websites and looking for the search engines like Google to feed us traffic. It's scary to think all your pages are ranked well and one day.. and poof..they are just gone like they never existed. Now all your traffic is gone or cut in half depending upon your marketing strategy. My question is what will you do if you had all your eggs in one baskets and your business needed that free traffic, and now your at zero. I will give you guys my take on this...after I get you all views. What Would Yo Do?
So you saying that will be your solution to continue to do backlinks..so what about your traffic..where will it come from? Because backlinks won't help you if it's not listed in the search engine.
Don't keep all your eggs in one basket. Build more sites (even if smaller), so that you still have income even if one of your sites gets a ban.
Personally I would find out what I did to cause Google to deindex the web site, fix whatever the problem is and if necessary submit a reinclusion request via GWT. Pretty straightforward really. Although, the easier solution is to make sure that whatever you are doing to promote your web site is not against Google policies and then you won't need to worry about it.
build more sites, if you are doing aggressive link building, etc do them on your test domains and monitor your progress. put links on your test domains to your money site
This is why i have alot of sites in differant niches and have many forms of revenue as someone else has mentioned dont have all your eggs in one basket.
