- Inspect link tags directly.
- Check rel attributes for flags.
- Audit page robots tags.

To check if a backlink is dofollow, inspect the HTML code of the linking page. You must confirm that the anchor tag has no rel attribute like nofollow or sponsored. By default, standard hyperlinks are dofollow. When you pay for placements or audit referring domains, verifying attributes ensures you receive real search value.
How to inspect link code in your browser
You do not need paid tools to inspect links. Modern web browsers let you audit code directly.
Step 1: Open the referring article and inspect element
Load the page where your link lives. Move your mouse pointer over the clickable text.
Right-click the anchor and click Inspect. Your browser opens developer tools and highlights the exact code. Our guide on how to check backlinks manually shows how direct checks catch errors that automated tools miss.
Step 2: Check the anchor tag for rel attributes
Look at the highlighted anchor tag in the code window. A normal web citation starts with an open tag and holds your target address.
Check if a rel attribute sits inside. If the code shows a plain reference with no rel values, search bots follow it freely. Official rules in the Google Search Central outbound link guidelines state that plain tags count as standard editorial citations.
Step 3: Review raw source code versus rendered DOM
Some sites create links with client code. That means initial server text can differ from what you view on screen.
Press Ctrl+U on Windows to view raw page source. Search the file for your domain name. If your web address shows up in plain HTML without flags, bots index it quickly. If the address only shows in developer tools after scripts run, review the Google Search Central JavaScript SEO documentation to make sure bots render the script.
Step 4: Check page-level robots tags and HTTP headers
A single link can look clean but still fail to pass rank. This happens when the entire host page blocks search bots.
Check the head section of the HTML code for a meta robots tag. If you see a robots directive that says nofollow or noindex, bots will skip every reference on that page. Next, check server response headers to make sure no header blocks crawler access. Our walkthrough on how to check if a guest post site is legit shows how to spot sites that block crawlers on paid posts.
Backlink attribute rules and ranking influence
Link attributes tell search algorithms how to handle relationships between websites. Knowing each type helps you judge true link equity.
| Link Attribute | HTML Example | Default Search Action | Equity Transfer | Typical Use Case |
|---|---|---|---|---|
| Standard (Dofollow) | <a href="https://example.com">text</a> |
Follows citation, crawls target | Full equity passed | Editorial references, earned citations |
| Nofollow | <a href="https://example.com" rel="nofollow">text</a> |
Treated as ranking hint | No direct PageRank credit | Untrusted external citations, comments |
| Sponsored | <a href="https://example.com" rel="sponsored">text</a> |
Treated as commercial hint | No direct PageRank credit | Paid guest posts, affiliate placements |
| UGC (User Generated) | <a href="https://example.com" rel="ugc">text</a> |
Treated as community hint | No direct PageRank credit | Forum threads, user comment sections |
| Mixed (Sponsored Nofollow) | <a href="https://example.com" rel="sponsored nofollow">text</a> |
Treated as commercial hint | No direct PageRank credit | Strict publisher ad networks |
Search engines treat paid markers as hints. They do this to understand business relationships while keeping search results fair. The Google Search Central robots meta documentation explains how these tags help systems parse complex pages.
Audit anchor text along with link tags. Combining clean tags with mixed anchor terms keeps your profile safe. Our guide on how to check backlink anchor text shares safe ratio rules for steady growth.
How to audit backlink quality and vendor promises
When you buy guest posts, verify that published links match your vendor deal.
Essential backlink verification workflow:
- Inspect live anchor tags. Make sure the site owner did not add rel="nofollow" to your paid editorial link.
- Verify page indexation. Paste the article web address into search to verify that Google indexes the live URL.
- Examine source code canonicals. Check that the canonical tag points to the exact article URL and not another page.
- Check referring domain authority. Review site quality with our framework on how to check domain authority and traffic to avoid spam rings.
Finding mistakes early lets you ask site owners for quick fixes before warranties end. Trusted outreach teams deliver clean links that follow web standards.

Frequently asked questions
What is the HTML code for a dofollow link?
A standard dofollow link uses a regular HTML anchor tag without a rel attribute. HTML has no valid rel="dofollow" attribute.
How do you check if a backlink is dofollow in Chrome?
Right-click the link on the page and select Inspect. Look at the highlighted code in Chrome DevTools to ensure no rel attribute blocks crawling.
Can a page-level tag block a dofollow link?
Yes. A meta robots tag with nofollow stops search bots from passing ranking credit through every link on the page.
Does Google treat nofollow links as dofollow?
No. Google treats nofollow attributes as ranking hints. They do not pass direct PageRank credit in normal searches.
