Lately, looks like a lot of PBNs (private blog networks) get deindexed and not everyone have the tools to do a quick check to see how many of the domains in PBN are still indexed. This mainly should be helpful for guys that don't run their own PBN and mainly purchase the services. It's always good to see how many of those domains are actually indexed after you purchased those "high PR" blog posts. So, here are some quick tools: 1st: Pull up your report of your high PR blog posts. Most likely it's in the format: http://www.domain.com/my-awesome-blog-post/ http://www.domain2.com/my-awesome-blog-post/ http://www.domain3.com/my-awesome-blog-post/ http://www.domain4.com/my-awesome-blog-post/ Now, let's just pull the domains from that list by using the following tool: http://ontolo.com/tools-unique-hostname-extractor Just copy and paste all of your urls and hit "get hostnames" 2nd: Copy all of the domains and paste them in here: http://www.bulkdachecker.com/bulkindex/ To see how many of those domains are indexed (25 at a time). Also, if you want to check the DA / PR / IP address you can use the following tool: http://www.robingupta.com/bulk-domain-authority-checker.html This should quickly tell you if the network that you are using was hit or not. If all you see is "deindexed" then those links are pretty worthless.
