How to recover after blocking all the search engine spiders?

[GroupM]

I have the following problem - one of my clients (a Danish home improvement company) decided to block all the international traffic (leaving only Scandiavian one), because they were getting a lot of spammers using their mail form to send e-mails.

As you can guess this lead to blocking Google also since the servers of Google Denmark are located in the US. This lead to drop in their rankings. So my question is - What Shall I do now - wait or contact Google?

Any help will be appreciated, because to be honest I had never see such thing in action until now

Best Regards

One of our clients did this once. We restored the robots.txt to original version allowing robots to browse normally and pointed a few fresh links to the site. The site was back in the index within a week. If your site has thousands or millions of pages that may take a bit longer. We found that discovery through links leads to better and quicker indexation than when you simply submit to Google. Get Google Webmaster Tools account and ensure that Google has clear picture of your site.
