Sprout SEO Extension is a free extension for Chrome, Firefox, and Edge. It combines multiple tools for on-page SEO checks, SERP enhancements, and AI search analysis—and can easily replace three to five other extensions you may be using now.
Here’s how our extension can help you:
1. Check the most important on-page SEO data
Analyze the on-page SEO elements of any page and locate potential issues. The Page Info tab has several sections:
The “General Info” section covers:
- Title tag with character count and truncation warning
- Meta description with character count
- URL and canonical URL with match/mismatch badge
- Robots directives from meta tags, x-robots-tag, and robots.txt
The “Web Vitals” section shows:
- Core Web Vitals from CrUX field data (LCP, INP, CLS)
- Falls back to origin summary when page-level data isn’t available
This is especially useful for quick performance checks without opening PageSpeed Insights.
The “Content Metrics” section contains:
- Word count for thin content detection
- Heading inventory (H1–H6 counts)
- Full heading list with hierarchy visualization
The “Additional Checks” section covers:
- Hreflang presence with language/region codes
- Sitemap detection
- Schema presence indicator
You can Export Page Copy or Copy Headings to clipboard for content audits. There’s also a direct link to view the live robots.txt file.
Use Page Info for quick indexability checks before publishing, content audit triage, or debugging canonical and robots conflicts.
2. Identify various types of links on pages
Sprout SEO Extension makes it easy to identify different links on a page through the Links tab:
- Internal and external links (separated)
- Nofollow, UGC, and sponsored links
- Broken and redirecting links (click “Check Status” to fetch)
The tab lists all links on the page—including JS-generated links—with filters for query strings, blocked-by-robots, redirects, and error codes.
The “Highlight” feature is particularly useful. Click it to overlay color-coded badges directly on the page:
- Yellow = query strings
- Orange = nofollow
- Red = blocked by robots
- Blue = redirects
- Error colors for 4xx/5xx
This lets you visually scan link health without scrolling through tables. Great for catching mis-wired navigation or spotting external links that should have rel=”nofollow”.
Export the full link table as CSV for audits, or click any row to open the destination in a new tab.
3. Find missing alt text and oversized images
The Images tab surfaces image SEO issues fast.
You’ll see summary counts for:
- Total images on the page
- Images without alt text
- Images without title text
- Images without explicit dimensions
Each filter lets you drill down to just the problem images. The per-image detail pane shows alt text (or “Missing”), title, dimensions, file size, and the full URL.
Export options make this actionable. You can export:
- All images
- Only images without alt text
- Only images without title text
- Only images without dimensions
Use the Images tab for accessibility audits (prioritizing missing-alt fixes), performance checks (finding oversized assets), or CMS QA (verifying lazy-loaded images rendered correctly).
4. Validate structured data with one click
The Schema tab detects JSON-LD and Microdata on the current page.
Detected schema types appear with counts and emoji labels for quick scanning:
- Article 📰
- Product 🛍️
- FAQPage 🤔
- BreadcrumbList 🍞
- Event 🎉
- Recipe 🍳
- VideoObject 🎥
- LocalBusiness 🏪
- JobPosting 💼
- Review ⭐️
- WebSite 🌐
- WebPage 📄
Unknown or unsupported types are flagged so you know what needs attention. You can expand raw JSON-LD snippets to inspect the markup directly.
One-click validation is the killer feature here. Buttons let you:
- Open Google Rich Results Test with the current URL
- Open schema.org Validator with the current URL
- Export or copy the schema payload
Use this for pre-publish validation loops (test → fix → reload → retest), confirming all expected types render, or debugging why rich results aren’t showing.
5. Trace redirect paths and read HTTP headers easily
See if you reached the destination page via a redirect and trace the entire redirect chain—including any intermediate hops.
The HTTP Headers tab shows:
- Status code (color-coded: green for 2xx, blue for 3xx, red for 4xx/5xx)
- Scheme (HTTP/HTTPS with a lock icon)
- Full redirect chain with each hop’s status and destination
For your own website, you can check if redirects were implemented properly and whether the right method was used (301 vs 302).
This tool also displays the complete HTTP response headers, which can be challenging to access for casual browser users. Headers you’ll find include:
- server, content-type, content-length
- cache-control, expires, vary
- x-robots-tag (critical for indexability—and you won’t find this in page source!)
- x-frame-options, content-security-policy, referrer-policy
There’s also a built-in status code reference table explaining common codes like 200, 301, 302, 404, and 503.
Use HTTP Headers when debugging indexability issues (reconciling x-robots-tag vs. meta robots), verifying caching before performance tests, or auditing security headers.
6. Preview social sharing tags
The Social tab validates Open Graph and Twitter Card metadata before your content goes live.
Facebook / LinkedIn Preview shows:
- og:title, og:description, og:image, og:url, og:type
- A placeholder card appears if tags are missing
X (Twitter) Preview shows:
- twitter:title, twitter:description, twitter:image, twitter:card
- Placeholder card if tags are missing
Reddit Detection is a unique feature. The extension checks if the URL was ever shared on Reddit. If shared, you’ll see the score, comments, subreddit, age, and a direct link to the thread. If not shared, there’s a quick “share it now” link.
Use Social for pre-campaign checks (verifying image dimensions before scheduling posts), duplicate tag cleanup, or monitoring whether your content gained Reddit traction.
7. Capture AI search insights
The AI Insights tab extracts data from AI-powered search platforms—a feature you won’t find in most SEO extensions.
Supported platforms:
| Platform | What’s Captured |
|---|---|
| ChatGPT | Search queries, web citations, AI reasoning/thoughts |
| Gemini | Queries, source attributions |
| Google AI Overviews | Citations from AI-generated SERP answers |
When you’re on a supported platform, the extension captures:
- Original input prompt — what you asked the AI
- Search/model queries — internal queries the AI used to gather information
- AI reasoning/thoughts — the model’s chain-of-thought (when available)
- Citations — domain, title, and URL for each source
You can export citations to CSV, copy all queries, or copy all citation URLs with one click. Past conversations are cached for instant recall.
Use AI Insights to track which sources AI models cite for a topic, research what queries AI uses behind the scenes, build citation lists for fact-checking, or monitor AI Overview presence on your target SERPs.
8. Launch third-party SEO tools instantly
The Other Tools tab is a launchpad for external SEO platforms. One click opens the current page or domain in:
| Tool | What Opens |

| Search Console | Page in GSC |
| Google Site Search | site:domain.com query |

9. Check search rankings in other countries

Tips for power users
- Pin the extension so you always see the icon and can click it instantly.
- Use SERP widgets sparingly — toggle off when you just want to browse.
- Combine tools — open PageSpeed + WebPageTest in parallel for lab + field views.
- Export early — grab link/image/schema exports before making changes so you have a baseline.
- Check redirects before linking — use HTTP Headers to confirm destinations before adding internal links.
