So this is what we've done:
Made a list of most relevant keywords to WellyBox. Because our product is best for freelancers and small business - there are wide topics we can talk about, but for our first few articles- we decided to write about things related to the core of our product.
Inserted the kw into SEMrush (was looking also into Ubersuggest- not sure how beneficial is it, what do you think?) and got insights – search Vol, and difficulty + ideas for longtail keywords.
Created a doc on excel with all the collected data– KW, Vol, KD.
We searched those kw in google, scrolled the first 2 pages and tried to find smallish websites (>30K visitors/m) that ranked (by Similarweb).
After we had a URLs list of small sites that ranked – We inserted those URLs into SEMrush and wanted to see if there is actually traffic coming into those URLs.
The ones without traffic we deleted, and for the ones with traffic (30+ visitors a month), we checked the keywords that bring them traffic.
Now we have a new list of keywords that not only related to us directly, but it's also possible for us to rank for and get traffic to our site.
It took some time, but I'm pretty happy with the process so far.
Take a quick look : www.wellybox.com . This is the "before"...
