I usually use scrapebox backlink checker to weed out the dead links from my seo campaign output before sending links for indexing. Today I decided to try turbo ranker backlink checket and results were quite pleasant. So I decided to check the efficiency of both the tools for same links file. Both are free tools. Sample link file had 401 URLs (where my backlink was placed). Thread count for both tools: 10 Scrapebox tool found results: 117 Turbo Ranker found results: 166 I manually tested the links that scrapebox failed to report as live but TBR reported as found and I could verify them as live links in my browser. I think TBR link checker is more efficient.
