In short:

- TheTool, listed in a previous version of this ranking, was bought by App Radar in 2021: App Radar is the one assessed.
For a mobile app, visibility is won first in the stores, then in web search and AI answers. This ranking assesses six players, agencies and platforms with a consulting team, against the same criteria and based on the information they publish. The scoring grid and detailed results are in the “Ranking methodology” section.

Its SEO and GEO expertise is led by a Team Lead SEO/GEO named on its website, and the group organises its own events: a conference on the shift from SEO to GEO on 5 May 2026, a morning session on ChatGPT Ads on 16 September 2026.
For apps, datashake publishes Google App campaigns (Search, YouTube, Display, Discover) to grow installs and engagement, paid social campaigns and an app tracking offer (installs, in-app events and purchases). Its Cheerz case study is quantified: +233% app installs and a customer acquisition cost brought from 184 to 42 euros, after moving the Meta campaigns to the AEM protocol. For this ranking, datashake states that it also offers App Store and Google Play listing optimisation.

The agency publishes an app case study, Trainsweateat (+11% App Store downloads, +8% subscription revenue), organises its own conferences and has a 4.8 out of 5 rating on Trustpilot.
3. AppTweak, the platform and its consultants

Its consulting offer combines “an in-house team of app growth consultants” with its tool, and covers keyword research, listing optimisation and Apple Ads campaign management. ASO strategy is led by Simon Thillay, Head of ASO Strategy and Market Insights.
AppTweak publishes its tool pricing (from 79 euros per month), a tool tracking app visibility in AI search and quantified case studies: +140% daily installs from search in three months for iVisa, almost +60% App Store listing conversion for The North Face. In 2026 it runs its AppTweak Amplify event tour (Tokyo, Seoul, New York, Berlin, London, San Francisco).
4. Phiture, the mobile growth frameworks
Founded in 2016 in Berlin, with offices in New York, London and Barcelona, Phiture is a mobile growth agency of more than 100 people, known for its published frameworks, the Mobile Growth Stack and the ASO Stack. Its ASO offer relies on PressPlay, its proprietary platform for creative testing across app stores, its paid search offer covers Apple Search Ads and Google App Campaigns, and its acquisition campaigns extend to social networks (Meta, TikTok).
Phiture publishes quantified case studies: +61% downloads on iOS and +53% on Android for Deezer after a first keyword optimisation round, +18% installs via search for Headspace. It hosts the Growth Phestival in Berlin (15 September 2026) and launched its Phield Notes webinar series in 2026.

TheTool’s website now redirects to App Radar, which combines an ASO platform (from 69 euros per month) with an app marketing agency, including paid acquisition on Apple Search Ads, Google App Campaigns and social networks (Meta, TikTok, Snap).
App Radar publishes quantified case studies, such as Kingdom Rush (installs more than tripled) or ProCamera (+28% listing conversion, +25.8% revenue).
6. Noiise, ASO within an SEO agency
With seven offices in France, Noiise offers ASO to “gain lasting visibility” in the stores, complemented by Google Ads campaigns for apps, Apple Search Ads and Facebook Ads and Twitter Ads campaigns optimised for installs. Its services start from 900 euros per month.
Mobile SEO and ASO: two complementary disciplines
App discovery goes through two channels.
ASO optimises the stores: title, keywords, description, icon, screenshots, reviews. It is iterative work, where each element of the listing affects its ranking and conversion rate.
Mobile SEO optimises web search: app landing pages, structured data, deep links into the app. It is the entry point from Google to the listing.
Paid acquisition (Apple Ads, Google App Campaigns) often complements both, and app visibility in AI answers is becoming a subject in its own right.
Ranking methodology
Each player is assessed against the same eleven criteria, based on public information about it (its official website, its offer, pricing and case study pages, its legal notice, the trade press) and on reviews published on Google and Trustpilot, collected on 22 October 2026; criterion 9 (paid social for apps) was collected for all players on 25 October 2026. datashake, the parent company of the site’s publisher and a sponsored feature, was assessed on 25 October 2026 based on its public information and on information it provided for this ranking. The first three criteria are common to all Journal Marketing agency rankings; the other eight are chosen for this ranking, including the last four, specific to ASO and app acquisition. Players publishing an ASO offer are included, as well as datashake, whose ASO offer was provided for this ranking. TheTool, bought by App Radar in 2021, is assessed under the name App Radar.
Scoring grid. Each criterion is worth 1 point if it is met (Yes); all other criteria are marked N.A (not applicable, as the data was not found by the editorial team) and are worth 0 points. All criteria have the same weight, 1/11 of the overall score each. The position follows from the overall score. In case of a tie, the player benefiting from a sponsored feature, indicated in the article, comes first and holds its own rank alone; then the player with more points on the ASO criteria, then alphabetical order. Among the other players, two players with the same overall score and the same points on the ASO criteria are ranked as tied at the same rank, and this is shown next to their rank.
