What Is Dr. Link Check and What Does It Do?
Updated
Dr. Link Check is a web-based broken-link and malicious-link checker. You give it a start URL, and its bot crawls the HTML and CSS of your site to find internal page links, outbound links, and links to images, style sheets, and other resource files. It then runs each link through several checks and produces a report of the links that need attention. It fits best when you want to audit a whole site rather than test one URL at a time, and when you want problems surfaced in a report you can sort, filter, and export.
What it checks
Each link the crawler finds passes through multiple checks, so a "working" link that actually points somewhere unintended still gets flagged.
| Check | What it looks for |
|---|---|
| Broken link check | Malformed URLs, servers that respond too slowly, invalid SSL certificates, and error return codes such as 404 (missing page) or 500 (server error) |
| Blacklist check | Whether the link appears on blacklists for hosting malicious content |
| Soft error check | Servers that return a 200 OK success code while the page content indicates something is wrong with the link |
The site frames the stakes plainly: non-working links are annoying and reflect poorly on professionalism, can drive visitors away, and can negatively affect search engine rankings. Links to malware or phishing sites are worse than dead ones, which is why the blacklist and soft-error checks sit alongside the basic 404 hunt.
How a check runs
- Enter a start URL. The bot begins there and crawls the HTML and CSS of the entire site.
- It collects every link it can find — internal pages, outbound links, images, style sheets, and other resources.
- Each link goes through the broken-link, blacklist, and soft-error checks.
- You get a report ranging from a high-level summary down to the exact locations of the found links in the code.
The report is the part that makes the tool practical for fixing things: results can be sorted and filtered in various ways and exported to CSV for further processing in Microsoft Excel. That means you can hand a filtered list of 404s to whoever owns the content, or work through outbound links separately from image resources.
Scheduled checks and customization
You can configure checks to run automatically on a monthly, weekly, or daily basis and receive status reports by email. This is the feature that turns the tool from a one-off audit into ongoing monitoring — it lets you detect link rot early, before visitors do. The site also notes that it allows control over various aspects of a link check, though the specifics of that advanced customization aren't detailed in the available material.
When it's the right fit
- You're auditing an existing site and want every link checked in a single pass instead of clicking through pages manually.
- You care about outbound link safety, not just 404s — the blacklist and soft-error checks target links that resolve but shouldn't be there.
- You need to hand off fixes, since CSV export and code-level link locations make the report actionable for other people.
- You want recurring monitoring, via daily, weekly, or monthly scheduled runs with email reports.
If you only need to confirm that one specific URL loads, a full site crawl is more than you need. And note that the check interface requires JavaScript enabled in your browser — the page states this explicitly, so a script-blocked browser won't get you to the results.
