SEO Tools Showdown: SEMrush vs Ahrefs vs Moz Pro vs SpyFu


  1. I’ve tried them all. But I agree Semrush seems to be the best overall tool if you only have the budget (or the time) to choose one. I’ve also tried Moz several times, but have never really warmed up to it for my purposes. I find Semrush is just way faster and easier for me to use for the purposes I use it for. (The learning curve was kind of steep too in the beginning – I’m still not what you’d call a power user

  2. I’m trying all of them right now to see which I’ll subscribe to and it seems like they all differ wildly in results for the same searches with ahrefs being way ahead of the pack in my experience. I do wish ahrefs had a better on-page SEO tool like SEMRush and Moz though. Thinking of doing the base plans on ahrefs and Moz Pro combined and ditching SEMRush before renewal.

  3. I came across this page because I was looking for the best SEO tool to use and which would be my money’s worth. SEMrush is definitely number especially when it comes to keywords research. But for backlink analysis, nothing beats Ahrefs. That’s my opinion. Based on my research, Ahrefs is useful for backlink analysis and link building. I like the pros and cons you put in the article. I found that helpful. It made me understand which tool to get.

  4. Thanks for the comparison. Hmmm I’m wondering can I use SemRush to do niche/keyword research the same job as Long tail Pro? Or was intending use both LTP and maybe Ahrefs. I now see Ahrefs is more for backlinks…which is great but Im only starting out… so now Im thinking maybe SemRush could replace both?

  5. We are currently testing out both SEMRush and MOZ Pro for the next 30 days. I’ve been going through several of your articles on the comparisons between the two platforms and have been really impressed and appreciative of the insight you have provided on them. We have outsourced our SEO fulfillment for years but have decided to start bringing select clients in house. We are looking for strong insights to improve their rankings as well as clear and easy to understand reporting to provide to the client. Thanks for the information and tips!

  6. Hi,

    Thanks for the article, really gives some clear insights.I am currently testing out Ahref’s and have tested Moz and Semrush in the past as well. In my opinion Ahref’s UI is the best and clearest. I will have to test Moz and Semrush again i am afraid to be sure which one to start using. Have been using SE Ranking for rank tracking mostly but have noticed rank positions are not accurate most times.

  7. Great article. Before reading this I was practically sold on SEMrush. However, after reading this article and the comments from other readers, I’m realizing I shouldn’t be so quick to pull the trigger and that Ahrefs may in fact be what I’m looking for. I will most likely do the trial period for both before deciding, but this article definitely opened my eyes to Ahrefs possibly being my best option (instead of SEMrush). Thanks for taking the time to write this article. Great work.

    • Glad you liked the article, Sahil. I personally prefer SEMrush. Ahrefs is a close second! 🙂 Love its backlink analysis capabilities, but Ahrefs’ site audit feature is not as refined as SEMrush.

  8. I’m curious if you have an opinion on which of these would be best for someone not directly in the SEO field but trying to build an industry specific site with high organic ranking? Or more specifically, does Spyfu offer enough to make it worthwhile to effectively examine keywords I would like to rank for and analyze my and competitor back links and keywords so I can build effective SEO? I’m in real estate and honestly, the number of $99 per month services is starting to get hefty *but I also want to get ranked. Is there a free site (or similar) anybody reccomends that might accomplish most of this? Thanks!

  9. Hello.
    Do you guys really think something can beat semrush? I am a big fan of this tool and can not imagine myself using a different one.

    Interesting article though.
