SEMrush for keyword difficulty test?

They can't provide any real data on competition strength, impossible for organic SERPs. You'll have to manually research competition for each keyword you target.

I do like the data they have for researching competition keyword ranked positions. A little outdated data but usually still good enough to tap into competition keyword ideas.

It's only useful if you are in the niche and can use keywords you are currently ranked on as a baseline. So if in one niche, you are ranked on an 80, and you notice there's a keyword you want to rank on that's a 75 and the sites that are ranking are the same sites you see on the keyword that's an 80, then you get a pretty good idea.

You need to understand 2 things about the SR difficult tool. First of all the SR database is not that complete. Second it only works of the link power, not the relevancy. Check the keyword "buy a whale" SR reports it as a 81.25. This is because the pages that are ranked would indeed be pretty tough to beat, if they were actually about the keyword. Which they are not, so if you threw up a website that pretended to sell whales and targeted the keyword "buy a whale" it wouldn't be very hard to rank at all. This keyword wasn't the best example, sorry. "buy a real whale" doesn't show up in the SR DB. Also notice in the SERP there's spam pretty high up in the rankings, that's usually a good sign.

So the SR difficulty tool data is only valuable among relevant sites.

So, good luck with your new whale selling business. Seems wide open to me.

I tried "orange butter" it's an 86.42, apparently there's such a thing as orange butter. The top 10 is a bunch of recipes for it.

Things to look out for: the keyword "volcano alien" huffpost is #10, I'd stay away.

They have made certain factor to find out the SEMrush difficulty test, domain trust, Search over the Internet some of those factor you will found.
