Professional SEO consultant and web developer since '94. The tool had solid data and I found it to be very useful for the price.

Let's compare it against my go-to, Ahrefs, and former AppSumo deals SE Ranking and Serpstat (both of which have improved greatly since being sold here).

The tool was able to get 991 keywords against Ahrefs 6k, but to be fair it got most of the big ones and plenty to get started with. So for keyword research I give it a solid B. Data on tools like this gets better with time, so it's off to a great start. The same query, Serpstat gave 4.8k keywords, and SE Ranking gave 686.

Backlinks are hard to compete on. Crawling the web is expensive. 28k links vs 36k links in Ahrefs is very respectable. Serpstat was 22k, SE Ranking had 37k. So this is a solid player in backlink research.

Clustering tool: It's a bit sad as it only clusters 200 keywords, so it is not very useful for me. My project this morning was 2951 after cleaning the list. Nice addon for smaller sites or if you break up your lists, but not up to pro levels.

I haven't tried the search console integration or the SERP checker yet, but I believe there is already plenty of value here without them.

No one tool is best at everything, but this shows the value of Semdash at a lifetime price. If you need a general SEO tool, Semdash will give you a solid keyword and backlink research tools in one. For a lifetime price, I say max stack and enjoy.

*** Responding to Hazem ***
"No valid keywords found in the API response" - I'm unable to use the longtail tool. I think it's due to a bug (already reported) that won't let me save my OpenAI API key. I assume I'll be able to get more down the road. I still see plenty of value in the tool.

*** Follow up ***
We were able to fix the OpenAI API key issue with a quick patch. The "Longtail keywords" tool generated 3.9k keywords. These are impressive results, and I'm happy to work with this developer. A+ support.
