Use Google Search Console to find what keywords other people are using to find your website.
When you login to Google Search Console you first have to verify your domain.
Add your domain, then verify it.
Copy the code then go to your domain provider, in my case GoDaddy.
Select DNS – Manage DNSSEC DS Records
Once your domain is verified, Google will determine all the queries people are typing to find your site.
What to do with this info? Knowing what people are typing and knowing what pages they are finding, you can then work on improving your content so people will get better results.
