Our website scanner detects and helps you remove outbound and broken links from your site. It detects all types of links — iFrame, image, hidden and encrypted links — that may hurt your SEO and damage your search rankings.
Sites that link to low-quality websites send a clear signal to visitors and search engines that they don't care what they recommend. Sometimes hackers use your website to plant outbound links to their poor-quality resources, dragging your domain authority down and damaging the trust signals Google relies on for rankings.
Not only users hate broken links — Google and other search engines penalize them too. Broken links chase your visitors away and hurt your SEO rankings. When you lose your SEO rankings, you lose your customers along with them. Regular link audits are essential for maintaining a healthy site.
Our smart spider finds all types of hidden links that may hurt your website and your customers. Whether it's an image link, iFrame, or hidden encrypted link, our scanner will help you detect and remove them. These hidden injections often slip past visual inspection but get fully indexed by search engines.
Spammers actively look for compromised websites and use various exploits to insert hidden spam links into trusted web pages — boosting their own SEO at your expense. Our spider can help you detect and remove these stealthy injections before they trigger Google penalties or blacklisting.
Hackers typically make their hidden links invisible to administrators and visitors but fully visible to search engine spiders. Our outbound link detector acts like a search engine spider and detects all possible links on your website. It's extremely important to control external links from your domain — otherwise you can lose your SEO rankings and get banned by search engines.
Hackers and spammers can use your website to plant hundreds of links pointing to their poor-quality websites. This way they get better rankings in search engines while your website is punished for hosting low-quality outbound links — a double loss for your domain authority.
Not only users hate broken links — Google and other search engines treat them as a quality signal. Even a single broken link can impact your search engine rankings. This is why you have to take broken-link audits seriously and run them regularly as part of your security monitoring.
If a spammer gets access to your website, they typically plant hidden iFrame links pointing to their resources. This way they use your website to push their own pages to the top of Google. When Google detects such links on your site, you risk being banned because Google then classifies your website as low quality.
Many web design companies and developers insert images into website templates with a link back to their own website. There's nothing inherently wrong with it, but we'd suggest removing these links for SEO purposes — every outbound link counts toward how search engines evaluate your domain's link profile.
Did you download a free template or install a plugin from a third-party website? You should definitely scan your website for poor-quality links. Hackers commonly use free templates and plugins to inject encrypted links that are only visible to search engines, harming your domain authority without you ever noticing.
Our Smart Link Scanner can also identify other types of potentially harmful content such as malicious iFrames, redirect chains, poor-quality outbound links and cloaked URLs. It helps you keep your website clean and safe for visitors, customers, and search engines — combining SEO protection with advanced web protection.

Usually hackers make their hidden links invisible to administrators and visitors but visible to search engine spiders. Our outbound link detector acts like a search engine spider and detects all possible links on your website. It is extremely important to control external links from your website — otherwise you can lose your SEO rankings and get banned by search engines, even when your visible content remains intact.
Outbound links are one of the strongest signals search engines use to evaluate your site's quality. When Google crawls your domain and finds dozens of hidden links pointing to pharmacy spam, replica goods or low-quality affiliate offers, it concludes that your website is part of a low-quality link network — and your rankings drop accordingly. Recovery from this kind of penalty can take weeks or months even with professional malware removal, which is why proactive link auditing combined with continuous security monitoring is always cheaper than reactive cleanup.
Our Smart Link Scanner identifies all types of potentially harmful content — malicious iFrames, encrypted SEO links, doorway pages, cloaked URLs, broken links, poor-quality outbound links and obfuscated JavaScript redirects. It helps you keep your website clean, protects your search engine rankings, and ensures a safe experience for your visitors and customers. Combined with our enterprise website security suite, advanced web protection, WAF and 24/7 monitoring, you get a complete corporate website protection solution that defends your domain against link injection, malware, DDoS attacks and blacklisting.
