Safari's extension ecosystem is much more limited than Chrome or Firefox. Here's what actually works in 2026, what doesn't, and the best workarounds for Mac users.
The only major SEO extension with a maintained Safari version. On-page SEO report, redirect tracer, broken link checker, HTTP headers, country switcher — all free without an account. Install from the Mac App Store.
Full review| Extension | Safari | Chrome | Firefox |
|---|---|---|---|
| Ahrefs Toolbar | ✓ Mac App Store | ✓ | ✓ |
| SEOquake | ✗ No Safari version | ✓ | ✓ |

Step 1: Open the Mac App Store on your Mac and search for Ahrefs SEO Toolbar. Click Get to download — it's free.
Step 2: After downloading, open Safari → Settings (⌘,) → Extensions tab. Find Ahrefs SEO Toolbar and check the box to enable it.
Step 3: When Safari asks for permissions, click Always Allow on Every Website. This is required for the on-page audit and link checker to function.
Step 4: The Ahrefs icon will appear in Safari's toolbar. Click it on any page to run a free on-page SEO report.
For search volumes (Keyword Surfer gap): Use Google Keyword Planner in a separate tab. It's free with a Google Ads account and provides accurate volume ranges.
For SERP authority overlay (SEOquake/MozBar gap): With Ahrefs Toolbar on a paid plan, the SERP overlay shows DR/UR data. Free users can open Ahrefs Webmaster Tools for verified sites, or manually check authority via Moz's free Link Explorer.
The pragmatic solution: Many Mac SEOs keep Safari as their primary browser and use Chrome only for SEO research sessions. Chrome profiles let you keep an "SEO profile" with all extensions separate from your main browsing profile.
