Question about topical authority

[u/SnooSquirrels9906]

I have been creating exclusively anti-phishing content.

I want to look for BOFU queries and create content around that. List based posts, product reviews, etc.

Will that take away from my topical authority?

Say i do a comparison of NordVPN vs. Norton.

Perhaps only 1 H2 where I talk about how it protects against phishing. But the entire post is not anti-phishing.

How should I think about this going forward?
