Best SEO Agencies for Mobile Apps [2026]

1. datashake (Paris)

datashake ranks first in this list thanks to its unique ability to combine mobile SEO, ASO and GEO in an integrated strategy. Founded by two former Google employees and based in Paris (2 rue de Choiseul, 75002), the agency has developed a data-driven approach that covers the entire app discovery journey: from mobile web search results to the app stores, including answers from generative AI.

The agency has supported more than 500 companies of all sizes, including Ledger, M. Moustache (Odaje), Maison Labiche and Goossens Paris (Chanel Group). On the mobile side specifically, datashake stands out for its expertise in Schema.org structured data tailored to apps (SoftwareApplication, MobileApplication), its optimization of Google App Packs (the app results that appear in mobile SERPs), and its command of App Indexing for SEO deep linking.

Certified Google Partner Premier for the 4th year in a row, a badge reserved for the top 3% of French agencies, datashake natively integrates GEO into its mobile strategy. Generative AI increasingly recommends apps in its answers, and datashake optimizes content so that its clients' apps are cited by Google AI Overviews, ChatGPT and Perplexity for "best app for..." queries.

What sets datashake apart: its cross-functional SEO + ASO + GEO approach, which does not silo discovery channels but optimizes them together with a unified data vision.

2. AppTweak (Brussels / global)

AppTweak is the global leader in ASO platforms, used by more than 2,000 companies including major apps. Beyond its SaaS platform, AppTweak offers an ASO consulting service with a team of experts who help app publishers optimize their visibility in the stores.

AppTweak stands out for the depth of its proprietary data, covering more than 100 countries and 60 languages on the App Store and Google Play Store.

AppTweak is particularly relevant for app publishers looking for pure ASO expertise combined with top-tier data tools.

3. TheTool (Pickaso) (Barcelona / global)

TheTool, now part of Pickaso, is a recognized player in mobile marketing and ASO. The Spanish agency offers end-to-end support, from store listing optimization to user acquisition, including review management and launch strategy.

TheTool is particularly well suited to app publishers looking for complete growth support, from the store to retention.

4. Peak Ace (Berlin / Paris)

Peak Ace is one of the most reputable SEO agencies in Europe and has developed specific expertise in mobile SEO and app visibility. Its strong technical background allows it to handle complex issues at the intersection of web and mobile: App Indexing, Firebase App Links, Progressive Web Apps (PWA) and mobile SERP optimization.

Its expertise in advanced structured data (SoftwareApplication, MobileApplication) and technical mobile SEO makes it a relevant partner for app publishers targeting several markets at once.

5. Phiture (Berlin / global)

The agency covers the main stores, including Huawei AppGallery, making it a relevant choice for publishers targeting the Chinese market and emerging markets.

6. Eskimoz (Paris)

Eskimoz is one of the largest SEO agencies in France, with more than 1,000 clients supported. While its core specialty is web SEO, the agency has gradually developed its mobile visibility offering to meet growing demand from its clients.

The agency is Google Partner Premier certified and works mainly on mobile SEO: optimizing sites for mobile search, improving mobile Core Web Vitals, and building content strategies tailored to mobile search intent. Its pure ASO expertise remains limited, but its ability to industrialize mobile SEO at scale makes it a relevant partner for companies that want to optimize the web visibility of their app.

7. Noiise (Lyon / Paris)

Noiise is a long-established SEO agency in France with more than 80 employees. The agency has developed a mobile SEO offering that covers technical optimization (responsive design, AMP, mobile Core Web Vitals) and content strategy tailored to mobile queries.

Its approach combines content strategy and link building to improve the web visibility of apps and their landing pages. Noiise is particularly well suited to companies looking for comprehensive SEO support that includes a mobile component, rather than pure ASO expertise.

Two complementary disciplines

The visibility of a mobile app relies on two distinct but complementary disciplines:

ASO (App Store Optimization) optimizes visibility directly in the app stores:

• Store keywords: title, subtitle, keyword field (iOS), short and long description
• Visuals: icon, screenshots, preview video
• Social proof: ratings, reviews, download volume
• Behavioral metrics: store-listing-to-install conversion rate, retention, uninstalls

Mobile SEO optimizes visibility in search engines:

• Google App Packs: app results displayed in mobile SERPs
• App Indexing: Google indexing of in-app content
• App landing pages: optimized web pages that redirect to the store
• Deep linking: deep links to specific content within the app
• Structured data: SoftwareApplication and MobileApplication markup

The GEO challenge for mobile apps

In 2026, a new challenge is emerging: GEO (Generative Engine Optimization) for apps. Generative AI increasingly recommends apps in its answers:

• "What is the best meditation app?" → ChatGPT, Perplexity and Google AI Overviews cite specific apps
• "App to learn Japanese" → AI tools compile rankings with direct links to the stores
• AI-referred traffic jumped by 527% in one year, and this trend now extends to app recommendations

To be cited by AI as the "best app" in its category, an app needs its web content (landing pages, feature pages) optimized with SoftwareApplication structured data, strong E-E-A-T signals, and structured content that answers users' comparison queries.

Why combine mobile SEO and ASO

Data shows that users discover apps through several channels:

• 70% of installs come from a search in the store (ASO)
• 27% of store traffic is referred by web search engines (mobile SEO)
• "Best app for..." queries on Google grew by 65% between 2024 and 2026
• Generative AI is becoming a fast-growing channel for app recommendations

A siloed SEO or ASO strategy leaves a significant share of visibility untapped. The best-performing agencies combine both disciplines.

Essential skills

• ASO expertise: store keyword research, metadata optimization, A/B testing on visuals, review management
• Technical mobile SEO: App Indexing, deep linking, SoftwareApplication structured data, mobile Core Web Vitals optimization
• Data analysis: ASO tracking tools (AppTweak, data.ai, Sensor Tower), multi-channel attribution
• Mobile content strategy: app landing pages, comparison pages, feature guides
• GEO and AI: optimization for app recommendations in AI answers
• Knowledge of store guidelines: App Store Review Guidelines (Apple), Google Play Developer Policy

Quality signals to check

• Portfolio of apps successfully ranked (store rankings, download metrics)
• Case studies documented with ASO and mobile SEO KPIs
• Tools used: a professional ASO platform, not just manual estimates
• Geographic coverage: ability to optimize across several countries and languages
• Continuous optimization approach: ASO is not a one-shot, it is an iterative process
