Welcome to the Q&A Forum

(I searched but didn't find anything similar here)

When you start a campaign, what is your method for finding the best keywords to optimize on your site and to track? Please share methodologies and tools on Moz that you use. I of course use Keyword explorer, and choose the higher volume keywords, but I am not sure I am looking in the most effective places. Any discussion on this would be greatly appreciated.

I get this explanation on the grader:

Although using targeted keywords in H1 tags on your page does not directly correlate to high rankings, it does appear to provide some slight value. It's also considered a best practice for accessibility and helps potential visitors determine your page's content, so we recommend it. Over-using keywords, however, can be perceived as keyword stuffing (a form of search engine spam) and can negatively impact rankings, so use keywords in H1 tags two or fewer times. To adhere to best practices in Google News and Bing News, headlines should contain the relevant keyword target and be treated with the same importance as title tags.

But I have the keyword in an H1 tag, only once. So why am getting this message on the grader?

The URL is https://www.armsecuritysystems.com/business-security-systems/

The keyword is "business security systems"

Any insight would be greatly appreciated.
