How to find the top ranking websites in a specific niche

[decodx]

If you want to start writing for a particular niche, then it is better to start researching. I am wondering how you can find the top ranking websites within a specific niche?
There are services like "The top sites" by Alexa and "Top Website Rankings" by similarweb. Do you know of any others?

Search Google.

The top results are the top-ranking websites in that niche.

Seems pretty straightforward. Use incognito mode for best results.

Google is your Best partner if you have any concern about the top ranking then you probably search it.

If you write your keyword in the search engine, you will get the top list of websites that use the same keyword, and then you need to search for the other data from other sources. You can try to visit this page:

You can also use Semrush Keyword Research Tool to find profitable keywords.

I heard about using software to help you find that keyword but I do not use it because it is paid software.

When I try google search, I don't get results like SimilarWeb or Alexa.
For example, if you look at similar sites (competitors) for dell.com you will get these results:
Lenovo
Intel
Asus
Newegg
Bestbuy
Cdw
Delltechnologies
Microsoft
Ibm
Nvidia

https://www.similarweb.com/website/dell.com/#similarSites

But when I try google search for "related:dell.com" I get nothing. The same thing happens with many other domains, so I don't know how I could use google for that purpose.

I'm still looking for alternatives to SimilarWeb.com. I guess no one has encountered this problem before?
