FAQ

Are SEO browser extensions enough?

They are enough for quick checks and manual QA, but not enough for serious reporting, rank tracking or competitive research.

What is the difference between MozBar and Moz Pro?

MozBar is a browser workflow. Moz Pro is a fuller SEO platform. The user intent is different.

Should every SEO use a browser extension?

Most SEOs benefit from at least one quick-check extension, even if they also use a paid suite.
