The challenge was that the online card games space was already dominated by strong competitors, established domains and high-volume keywords.
The project had one important limitation: we could not rely on onsite changes or new content. The entire growth strategy had to be delivered through off-site SEO.
That meant every link, anchor and publishing source had to be selected with precision.
Instead of running one generic international campaign, we prepared separate off-site strategies for each market. We analyzed competitors’ backlink profiles, selected local publishers and focused on links from trusted domains with .de, .pl and .fr visibility.
The strategy was designed to strengthen the exact URLs that needed growth and support rankings for high-volume keywords such as “solitaire”, “solitär spielen”, “pasjans online” and “spider solitaire”.

SolitaireAvailable globally through app stores and web environments.As part of our cooperation, we supported Easybrain’s Solitaire with international link building on three competitive European markets: Germany, Poland and France.
After 6 months, the campaign delivered strong results across the key markets. What makes this result especially important is that the growth was achieved entirely through off-site SEO, without onsite changes or new content.
The German market delivered the strongest traffic growth. Several highly competitive keywords moved into or closer to TOP 10 positions, including “solitär spielen”, “solitär spielen kostenlos”, “spider solitär kostenlos” and “freecell spielen”.
In Poland, the strategy strengthened visibility for high-volume keywords such as “darmowy pasjans”, “pasjans pająk”, “pasjans online”, “freecell” and “pasjans klasyczny”. Some keywords moved into TOP 2, TOP 3 and TOP 5 positions.
In France, the campaign helped build momentum in a difficult market and improved visibility for “spider solitaire” related queries, including “spider solitaire”, “spider solitaire gratuit” and “spider solitaire classique”.
In this project, we had to prove that link building alone can move the needle, even in a highly competitive global gaming category. The key was not volume for the sake of volume, but local relevance: the right publishers, the right anchors and a different strategy for each market.
This case shows that off-site SEO can still drive measurable growth, even without onsite changes or new content.
For Easybrain’s Solitaire, the key was not one international link building template. It was a separate strategy for each market, built around local domains, local search behavior and the competitive landscape of each country.
In a category dominated by global players and extremely high-volume keywords, precise link building helped Solitaire grow visibility, strengthen rankings and increase organic traffic across multiple markets.
