Eskimoz (1,000+ clients, Google Partner Premier) offers mobile SEO: site optimization, Core Web Vitals, content strategy for mobile queries. Its pure ASO expertise remains limited, but its ability to industrialize mobile SEO at scale makes it relevant for large enterprises.

Noiise (Lyon/Paris, 80+ employees) combines technical optimization (responsive, mobile Core Web Vitals) and content strategy for mobile queries, adding a link-building dimension. Ideal for comprehensive SEO support with a mobile component.
Mobile SEO and ASO: two complementary disciplines
App discovery via mobile travels two distinct paths.
ASO optimizes app stores via title, keywords, description, icon, screenshots and reviews. It’s an iterative process where each element influences ranking.
Mobile SEO optimizes search results: Google App Packs, in-app indexation, landing pages and Schema.org markup. This is the web gateway to the app.
Key figures: 70% of installations come from store searches (ASO), but 27% of store traffic comes from web search. “Best app for…” queries surged 65% between 2024 and 2026. A siloed strategy leaves opportunities unexploited.
Budgets and concrete results
Investments vary by program scope:
| Program type | Monthly budget | Timeline for results |
|---|---|---|
| ASO audit with recommendations | 2,000 to 5,000 € | 2 to 3 weeks |
| ASO support on 1 app/1 store | 1,500 to 3,000 € | 2 to 4 months |
| Advanced ASO strategy multi-stores | 3,000 to 6,000 € | 3 to 6 months |
| Mobile SEO + ASO combined | 4,000 to 8,000 € | 4 to 8 months |
| Complete international program | 8,000 to 15,000 € | 4 to 10 months |
| ASO SaaS tool (platform access) | 300 to 1,500 € | Immediate |
ROI is measured in store rankings on target keywords, conversion rate from store listing to installation, web-to-store traffic (Google visits to store listings), and increasingly, in citations by generative AI (ChatGPT, Perplexity, Google AI Overviews).
