Really Tested this Method - Results
I didn't test it in the way the OP describes, as it's crazy to do something that is that repetitive when there are just so many readily available tools for automating it. I used scrapebox to do everything done in the OP 'en masse. So while I did exactly what the OP says to do in how URLs are gathered (where they come from), all gathering/testing was done in an automated fashion.
I wanted to see just how viable this could be for snagging some blogs that already had PR. Fired up scrapebox, and here were my results (this took about an hour and a half, with me only having to actually "interact" and do something for a total of about 15 minutes...the other hour and fifteen minutes were just waiting while SB did it's thing). Numbers are rounded to the nearest 1,000:
- Scraped 30,000 blogger.com profiles from google
- Extracted 294,000 URLs from those 30,000 blogger.com profiles
- Of those 294,000 URLs extracted from the blogger profiles, there were 193,000 unique "something.blogspot.com" URLs
- Of those 193,000 blogspot.com URLs, a total of 18,000 were either set to private, deleted or deleted & able to be registered
- Of those 18,000 a total of 8,000 were deleted
- Of those 8,000 that were deleted, 1,100 had a pagerank of 1 or higher (highest was 6)
- Of those 1,100 that had a pagerank of 1 or higher 18 of them were available for registration immediately (highest was PR 4)
- So out of 193,000 blogspot.com URLs gathered in a random fashion, 4% were deleted but not able to be registered
- So out of 193,000 blogspot.com URLs gathered in a random fashion, 0.5% were deleted with a PR of 1 or higher
- So out of 193,000 blogspot.com URLs gathered in a random fashion, 0.009% were deleted with a PR of 1 or higher and were able to be registered immediately
