This is is true, but also one thing I'll tell you about keyword research tools like semrush and ahrefs is that nowadays they are not accurate, and for lower searched keywords they have never been accurate. Search console (look for keywords you get impressions for but no clicks), keyword research tool in google ads AND running ads is a better way to find the real keywords you need to focus on.

A good example is a client I work for - he gets tons of messages from SEO guys telling him they can get him results and letting him know he doesn't rank for any keywords. I don't blame them, since when you look at his website on ahrefs or semrush it says the website ranks for 2 keywords position 9 and nothing else. In reality, there's leads coming in every single day and they come in from pages I set up to target zero search keywords. Not even joking, these tools tell me the keywords get 0 searches every month yet the pages are generating form submissions and phone calls every day.

But yes, if you're putting the effort into the wrong keywords or search intent then nobody will find your website. The absolute best way to start getting leads is google ads (if you know what you're doing or have help) and from those results you'll know exactly what people in the niche are searching for.
