A mid-sized Danish IT consulting agency had tried several SEO agencies and freelancers. Still, the website rankings and organic traffic did not respond to any initiative; it was like the website was frozen into a fixed position.It turned out that the main problem was a competitor, who had been doing negative SEO in terms of link bomb continuously over a few years. This was holding the agency’s website down and put it at risk of being penalised by Google for the aggressive flow of new low-quality links coming to the website.The initial scan of the domain showed a very high risk-level:The competitor was also using anchor-texts that had absolutely no relevance to this website, thereby diluting the website anchor-text profile. I also noticed a high level of links coming from porn site. I have only rarely seen this level of aggressive, negative SEO. See a cloud of anchor texts aimed at the website below.I took care of the technical problems, disavowed the spammy links. The results came quickly as the organic traffic increased. After the clean-up, I started ‘normal’ link building and on-page optimisation.The final result of my work was a 10X higher visibility in the search engines.But in the end, it’s the conversions that count, and here I managed to push the conversion rate up by short of 1.100% and the number of transactions in the shop by 2.800%.
