Frequently asked questions
What is the main difference between MozBar and Ahrefs SEO Toolbar?
MozBar and Ahrefs SEO Toolbar overlap in the same job, but they optimise differently: one is tuned for speed and simplicity, the other for depth and control. The side-by-side table above shows the current ratings, install base, pricing and who each one is built for, all synced from the public Chrome Web Store listings.
Can I use MozBar and Ahrefs SEO Toolbar together?
In most cases yes — Chrome runs extensions independently. Keep both only if they cover different needs, because each active extension adds memory use, page scripts and one more set of permissions to trust. If their features clearly duplicate, pick one and remove the other.
Is MozBar or Ahrefs SEO Toolbar free?
Check the pricing row in the comparison table: it reflects the current model for each extension, whether that is free, freemium with paid limits, or paid only. Free tiers change often, so the store listing linked from each card is the source of truth.
Which one is safer to install?
Compare the permissions each one requests on its Chrome Web Store page and prefer the extension asking for less. Also look at the developer, the last update date and the review count — an actively maintained extension with a large install base and narrow permissions is the safer choice.
How often is this comparison updated?
Ratings, review counts and install numbers are refreshed nightly from the Chrome Web Store, and the editorial verdict is reviewed whenever either extension ships a significant change.
