  1. Hey Brent,

    I’d appreciate your advice.
    I’ve been using SEMrush for quite some time and it’s a solid choice but updates rarely. So I switched to Serpstat because it’s rapidly growing both in functionality and bases.
    Can you suggest me similar tools that can compare URLss back to back like Serpstat does. (I’m not talking about domain vs. domain feature)

    THNX!

    • Hi George,

      Thanks for commenting on this older post of mine.

      Unfortunately, I don’t do much work with SEO these days — so I really have no new tools to recommend trying. I have, however, heard good things about Serpstat.

      Sorry I can’t be of any more assistance to you. Good luck!

      Best,

      Brent

  2. Hey Brent,

    Ubersuggest is my favorite and they have recently updated their site. These keyword suggestion tools help us to think about various topics and what our audience is searching on the internet.

    Thanks for sharing these tools with all of us.

    • Hi Yogesh,

      It’s been a while since I have dove into keyword tools in much detail. This was one of the very first posts I ever published on my blog back when I hadn’t really narrowed down my target audience much yet.

      Still, I’m glad you found this post helpful. Thanks for commenting, and thanks for the suggestion.

      Positively,

      Brent
