We solve the link data puzzle for you

Every link database has only a piece of the world’s link graph. Even Google. Only by combining them all together you have a chance to get a 360-degree view of your backlink profile.

LinkResearchTools combines link data from 25 link data sources. We then clean, re-crawl and verify the link data for you. You get a new crawl with every report you create. No other SEO software or online marketing tool provides you with as rich, and accurate data in one single central system as LinkResearchTools (LRT) does. The completeness and accuracy of LinkResearchTools are not only legendary but also the reason why Christoph C. Cemper built LRT®. Every other product just presents you the fragments of your backlink profile that it has in their index, we combine and clean all data pieces for you.

Remove a Google Penalty fast

Google Penalty Recovery

Have you been hit by a Google? Are you dropping in rankings for your main keywords? Did you receive a Google Manual Action Penalty notification in your Google Search Console account? Run a comprehensive backlink audit to regain your lost visibility and organic traffic quick and easy. We can even make the disavow file work faster by helping links getting crawled to help you speed up the recovery process.

Google Penguin now part of the Google Core, so our features for analysis per directory, per page, per keyword group are the perfect solution to the “more granular” Google Penguin signals, filters and penalties.

We have technology and a machine learning system that helps you simulate a link before it’s built. Only LRT has this in the Link Assessment Tool LORT. Because in the post-Penguin era, every link building mistake can lead to a the Google algorithm (with Penguin algo in the core) holding you back on those keywords you want to rank for, or even a manual action, that you need to fix later, at least using a disavow or link removal. To avoid these issues, you need to make sure that your new backlinks are strong and have a low risk.

Monitor new backlinks to any domain

Monitor new inbound links

Link Alerts (LA) automatically scans the web for new links; collects link data from 25 link sources and sends you an e-mail notification when it detects new links. It’s the best way to protect your site from negative SEO and monitor your competitor’s new backlinks. You will be surprised to find great link building opportunities and interesting business development ideas.
