A warning and a question. Had good ranking sites. Did load of Xrumer blasts (paid for, not my own). All great, helped them rank. Brilliant. Then I decided to ping them. Big mistake. #1 site down to <50 in a day then <100 in 2day then deindexed (nothing in site:domain). Not just those sites, but every one with a webmaster tools verification code. I have a site that has exactly the same template, but with no verification code. Aslo Xrumered, but not pinged. Still indexed and #3. So beware (or do this to your competitor). Have removed the verification code. Howe long do you think the deindexing will last?
