The hardest part of link building is knowing where to look. The Backlink Opportunity Finder builds ready-made Google search queries for your niche using the same search operators experienced SEOs use to uncover guest post pages, resource pages and link roundups.
Enter your niche keyword, and add a competitor domain if you have one. You get a table of queries, each with a one-click link that opens the search on Google and a note explaining what that query is designed to find.
Work the list from top to bottom, vet each site for relevance and quality, then pitch with a specific idea instead of a generic request.
