I am purely web developer who is now dabbling into SEO territory and learning SEO throughly and deeply.I heard about this tool from a Senior who is in this business longer then me. I really like wat i saw i did my research through different videos and revies and l i really like the support that David is giving. I have not tested the software myself yet. I beleive in the support they are providing they seem genuine, logical and serious i read through all there reviews and questions as well. I am hopeful this would be my goto tool for my SEO journey i Got tier 4 lifetime deal. I am all in and I am hoping for the best and hoping that SEOCrawl does fufill all its promises regarding features and support and continues to do it in Future.....Best wishes from my side.
