Dear all BHWers, I am thinking to get more tools for my SEO efforts. Right now, I can only afford about $100 for analysis tools. Which one I shall use? I am interested in Moz and in Ahrefs. Moz : Gives more than just backlink information, but also gives better Open Site Explorer, On Page Grader, and Competitive Analysis that can be useful to me Some of the features are useless (I got SERPBook for Rank Tracking, and I trust Google Analytics more than Moz Analytics, etc.) A lot of threads I read here said that Moz backlink information is the least accurate. Moz has not many recommendation from this forum. Can show some useful metrics (PA/DA, Trust Flow) Ahrefs : Said to have one-of-the-best backlink information Has a lot of recommendations in this forum. Only provide backlink information, nothing else. Basically, I need a tool that can generally show my backlinks (so that I can manage them better, and I can be sure that services I bought really works), and also a tool that can generally assist me in grading my website and knowing my competitor's backlink or keyword profile. If you guys have any other tools rather than this two, that can suit my need, please do give your advice. Thanks a lot.
