Visibility in the TOP10 More Than Tripled: Mobile Vikings SEO Case Study
When we started working with Mobile Vikings, the brand had the fewest visible keywords in the TOP3 and TOP10 among the MVNO operators it was compared with. A year and a half of consistent SEO work was enough to build visibility at the level of the leader in that comparison.
(01) PROJECT OVERVIEW
Building visibility from an underdog position
We began working with Mobile Vikings in April 2025. At the start, mobilevikings.pl was in an underdog position – compared with close competitors such as virginmobile.pl, njumobile.pl and plushbezlimitu.pl, it had clearly the fewest keywords in both the TOP3 and the TOP10. Our goal was to build organic visibility that could genuinely compete with these brands in the same niche.

(02) Challenge
Three overlapping problems
At the start of the collaboration, we faced several overlapping problems.
The first was how content was organized on the domain. The Mobile Vikings blog lived on a separate subdomain, and Google treats a subdomain as a separate domain. In practice, this meant the blog content did not fully support the visibility of the main website, even though the main website was the one driving conversions.
The second was the risk that comes with technical changes. During the collaboration, we migrated the entire website and then moved the blog from its subdomain to the main domain – and any migration of this kind carries a real risk of losing visibility if it is not carried out carefully.
The third and most long-term challenge was the competition itself. Mobile Vikings was competing not only with the three MVNOs featured in this case study, but also with the Big Four – Orange, T-Mobile, Play and Plus – for the same highly competitive mobile-offer keywords.
An additional obstacle was that some competitors, including all three MVNOs we compared, offer subscriptions with a phone on an installment plan. This gives them access to a much broader area of device-related and how-to keywords, which Mobile Vikings – in line with the profile of its offer – deliberately does not cover on its blog.
(03) Action plan
Strategy: systematic visibility building instead of isolated actions
Goal: build Mobile Vikings’ organic visibility at a level comparable to or higher than that of its direct MVNO competitors, despite a weak starting point and strong competition for the same keywords.
Actions:
- Migrating the entire website
- Migrating the blog from the subdomain to the main domain
- Regularly publishing content that is valuable to users and keeping the offer content up to date
- Growing the domain’s link profile
- Consistently building Topical Authority through topic clusters and external links from industry sources
- Continuously monitoring the site’s technical health and responding to issues quickly
- Ongoing search for new areas of competitive advantage and testing of new solutions

Step by step
Step 1: Website migration
The first step was migrating the entire mobilevikings.pl website. A change like this always carries the risk of a drop in visibility, so we planned the process to keep that risk to a minimum – the migration went through without any loss of existing search positions.
Step 2: Moving the blog off the subdomain
The next step was moving the blog from its separate subdomain to the main domain. As a result, the blog content – instead of building the visibility of a separate address that Google treated as a distinct entity – began to fully support the visibility of the main website.
Step 3: Continuous, parallel work on visibility
Since the website migration was completed, we have been carrying out the remaining activities continuously and in parallel, without dividing them into separate stages: regularly publishing and updating content, growing the link profile, building Topical Authority through topic clusters, monitoring the site’s technical health, and testing new areas where an advantage over the competition can be built.
(05) The result
Visibility growth in the TOP10 and TOP50
A comparison of Senuto data from April 1, 2025 (the start of the collaboration) and October 21, 2026 shows the scale of the change:
TOP3 (number of keywords ranking in the top three results)
| Domain | 1.04.2025 | 21.10.2026 |
|---|---|---|
| mobilevikings.pl | 624 | 1,980 |
| virginmobile.pl | 1,260 | 1,612 |
| njumobile.pl | 1,907 | 1,992 |
| plushbezlimitu.pl | 1,838 | 2,252 |
TOP10 (number of keywords ranking in the top ten results)
| Domain | 1.04.2025 | 21.10.2026 |
|---|---|---|
| mobilevikings.pl | 2,709 | 8,311 |
| virginmobile.pl | 4,739 | 6,762 |
| njumobile.pl | 5,556 | 4,512 |
| plushbezlimitu.pl | 5,935 | 6,428 |
TOP50 (number of keywords ranking in the top fifty results)
| Domain | 1.04.2025 | 21.10.2026 |
|---|---|---|
| mobilevikings.pl | 17,186 | 18,957 |
| virginmobile.pl | 27,696 | 16,902 |
| njumobile.pl | 32,180 | 11,130 |
| plushbezlimitu.pl | 21,161 | 16,746 |
In the TOP3, Mobile Vikings more than tripled its number of visible keywords (from 624 to 1,980) and reached a level close to njumobile.pl, while overtaking virginmobile.pl. In the TOP10, the number of keywords also grew more than threefold, from 2,709 to 8,311, which put Mobile Vikings in first place among the compared domains in that category. The TOP50 shows a similar picture: mobilevikings.pl was the only one of the four compared websites to increase its number of visible keywords over this period, taking the lead.
We achieved this result despite deliberately giving up a whole segment of how-to and device-related keywords, on which competitors offering phones on installment plans build their visibility. Mobile Vikings’ visibility is therefore the result of systematic work in a narrower area, more closely matched to the brand’s offer – not the result of covering a wider range of topics than the competition.
