Here is how Ahrefs SEO Toolbar can make your everyday SEO work easier:

1️⃣ On-page SEO report

By clicking on the extension icon or using a keyboard shortcut when browsing a web page, you can access an on-page SEO report that includes:

🔹 Title and Description (for JS-powered websites, you can compare tags in raw HTML and on the rendered version)
🔹 Canonical URL
🔹 Indexability and crawlability aspects (Robots Meta Tags, X-Robots-Tag, canonical tags)
🔹 Heading structure of content
🔹 Page word count
🔹 Social tags (Open Graph Tags and Twitter Cards)
🔹 Images

2️⃣ Structured data checker

This extension can display JSON-LD structured data in a clear and compact view. You don't need to dig into the page code to check its schema.org data.

We've also added a quick way to validate structured data.

3️⃣ Link checker, broken link checker, and link highlighter

Ahrefs SEO Toolbar can read all the outgoing links on a page and highlight them based on the filters you set, including:

🔹 External links
🔹 Internal links
🔹 Nofollow links
🔹 UGC links
🔹 Sponsored links
🔹 Their combination

Moreover, you can check the status of external links and identify broken links and redirects.

4️⃣ HTTP header reader and redirect tracer

With Ahrefs SEO Toolbar, you can easily check HTTP response headers for the URL you visit. This feature can also help you track the redirects or redirect chains that took you to the destination URL. You can check HTTP response headers for every URL in a redirect.

5️⃣ Country changer for SERP (search location simulator)

Ahrefs SEO Toolbar also includes a feature that lets you check search results in any country without needing a VPN or additional services. This search location simulator can help you better understand the differences in search results based on location and optimize your SEO strategy accordingly.

6️⃣ Domain highlighter for SERP

Add up to 10 domains that will be highlighted with color whenever they appear on SERP for the keywords that you're researching.
