Have An Infinite Supply Of Link Opportunities
When testing the effectiveness of scraping using keywords from a random niche, we discovered about 11 million unique domains without trying too hard. While you can certainly run these kinds of lists through a tool such as GSA SER, you can think beyond that. You could extract quality blogs from that list and send a mass email offering a guest post. Or maybe you could extract their external links looking for expired domains to use in your PBN? Domains which already contain valuable niche related links. The possibilities are endless.
