About LinkResearchTools®

LinkResearchTools (LRT) was founded in 2009 in Vienna, Austria by our CEO Christoph C. Cemper. However, the core idea for the company was born much earlier, in 2006 when Christoph and his team started developing software for accurate SEO consulting and link building services for their online marketing agency - which was founded back in 2003. That's more than 15 years of experience with links. No wonder our company name starts with the word "Link". We just love links. We enjoy discovering new ones. We'd like to become your link to online success!




Christoph C. Cemper

Founder & CEO


LinkResearchTools (LRT) is a software solution built to help you increase your web traffic and get more customers.


We envision a world in which every webmaster has full control and overview of his backlink portfolio at any moment!

The Purpose

Challenging the status quo is hard but inevitable if one wants to improve even a smallest piece of the Universe. We all know that the only thing that is constant is change. However, discovering what that change might look like is the toughest part of the equation. This is the exact same issue we dealt with when started thinking how to help our company to save time and optimize its processes. Time is the only resource you can never compensate. That's the reason why it's so important to us. Doing things the way you always have is easier.

On the other hand, finding new ways of doing things and thinking outside of the box is a pain. But this pain is also a secret ingredient of every invention, of every great product ever created. Being aware of the reasons why we do what we do, have helped us to focus on creating some amazing stuff. We're excited to share them with the world and help others to solve the problems we were facing as well.

The Process

We used to be link builders. We were an agency for link building. And as every other agency in this industry, we wanted to achieve great results, that is, high rankings in SERPs with minimum efforts invested. Easier said than done. Especially 10 years ago when there were not many specialized tools and software for links and SEO. Of course, we started like everyone else by pulling data together manually in Excel. Needless to say, we weren't satisfied with the results and with too much manual work involved. It was interesting in the beginning but soon enough we realized that it's almost impossible to continue doing things the old way. It started to become too slow and too inefficient. We had to change something and make some parts of our procedures a bit more automatic.

And this is the moment when our founder Christoph started LinkResearchTools (LRT) - the software company (SaaS). LinkResearchTools was built for link builders by link builders. We do not offer search engine optimization services anymore, but we enjoy helping SEOs and making their lives easier by providing and developing all the necessary tools for faster and more efficient link building. Even Google admits it - ranking without links is really, really hard!

The Product

Have you ever wondered why is it so important to do a full link audit and to have a clean backlink portfolio of your website? Ever heard of backlink disavow in Google Search Console? OK, we know these terms might sound little odd if you just have started your journey to learning everything about SEO. So, let's explain this in plain English.

Every website on the internet has its own backlink portfolio. When website A has a link pointing to a website B, that is called a backlink for the website B. Backlinks are amongst most relevant ranking factors for Google. Simply because they are connections between websites like rails are between metro stations - without them, search engine spiders wouldn't be able to find and visit other websites (stations). The more backlinks a website has, the higher the possibility to rank better in Google search. However, sometimes website A which is associated with a website B - could be hurting (on purpose or not) website B because of various reasons. This is called Negative SEO. Not all links are equal. There are good and bad, there are strong and weak links. Our mission is to detect their status.

Being a leader in backlink analysis isn't that hard - it only takes

15 years of experience and over 40,000 registered users.


We could compare backlink checking with bookkeeping. It's like bookkeeping for your website. This is constant checking of your assets (good, quality links) and your liabilities (bad, toxic links). If you ignore your liabilities, you could get into trouble with Google very soon. You could be penalized for having too many toxic links pointing towards your website. And this is the reason we invented (in 2012) - Link Detox - our most popular product. It helps you recover and protect your site from Google Penalties by cleaning up your backlink profile i.e. by doing the complete website bookkeeping for you.

With better-looking backlink profile, your site will rank higher. As simple as that. But we also developed several other tools which can help you optimize your link building. These are actually sets of tools for accurate Backlink Analysis, Link Audit and Penalty Recovery, Link Quality Checks, Competitor Analysis, Backlink Monitoring, Link Prospecting and Free Browser Extensions.

“We started using LRT for the Detox function after a negative SEO attack on our site. Not only was LRT instrumental in helping us clean up the links and recover the site but it has become critical to the way we do all of our marketing efforts. Most of our processes today are built around LRT and its tools and everything that we have learned from the LRT team. A must have tool for anyone serious about traffic”
