External Link Analysis
Audit Every Outbound Link You Have

TechySEO catalogs every external link on your site β€” links to HTML pages, images, PDFs, scripts, stylesheets, audio, and video files on external domains. Know exactly what you're linking to, verify it's all still live, and identify risky outbound link patterns before they affect your site's reputation.

What You Link to Reflects on Your Site's Trustworthiness

External links are a trust signal in both directions. Linking to high-authority, relevant sites strengthens your content's credibility and provides users with valuable references. Linking to spammy, penalized, or dead websites sends the opposite signal β€” and tells search engines your editorial standards are low.

Most sites accumulate broken external links invisibly over time. A cited study that moved. A partner site that went offline. A resource that's now a parked domain. These broken outbound links degrade user experience without any visible symptom until you audit them. Users who follow a broken external link don't just lose the resource β€” they lose trust in your site.

TechySEO checks every external link destination at crawl time β€” so you always know exactly what you're linking to and whether it's still live.

External Link Auditing Across Site Types

Content Sites

External Link Analysis β€” FAQs

Does TechySEO crawl external websites?
No. TechySEO only crawls your own site. For external links, it makes lightweight HTTP HEAD requests to verify the external URL is still returning a valid response β€” without crawling the full external page or any of its linked content. This keeps the verification fast and respects the external site's resources.
How often are external links rechecked?
External links discovered during a crawl are verified immediately. During subsequent recrawls, external links are rechecked at intervals based on your plan configuration. You can also manually trigger a recheck of specific external links or domains from the TechySEO dashboard without waiting for a full recrawl.
What file types are included in external link analysis?
TechySEO categorizes all outgoing links by the type of resource at the destination: HTML pages, images (.jpg, .png, .gif, .webp, .svg), JavaScript files, CSS stylesheets, PDFs and documents, audio files, video files, and other content types. This full categorization helps you understand your site's complete external dependency profile.
Should I use rel=nofollow on external links?
rel=nofollow is required for paid links and recommended for untrusted user-generated content β€” and links you don't want to editorially endorse. For editorial links to trusted, authoritative sources, standard dofollow links are fine and actually beneficial. TechySEO shows you which external links already have nofollow attributes so you can review your current implementation.
Can excessive external linking hurt my rankings?
Extremely high numbers of external links on a single page can dilute the link equity passed to your internal pages and may appear spammy to search quality reviewers. However, normal editorial external linking to relevant, authoritative sources is not penalized and can actually help. The key metrics are relevance of the linked domains and whether the linking pattern looks natural and editorial.
