--- title: Benchmark an App Store listing against the top apps description: A runbook for AI agents. Find where an iOS app ranks for up to 3 search keywords, compare its first screenshots with the top apps, and suggest 3 changes grounded in what those apps show. surfaces: [http-api] runtimes: [ any agent that can make an HTTPS GET, curl; viewing images helps but is optional, ] auth: none for the benchmark; a BrandBeacon account to A/B test screenshots endpoint: https://brandbeacon.dev/api/public/app-store/benchmark updated: 2026-10-10 --- # Benchmark an App Store listing against the top apps You are helping a person see how their iOS app's App Store listing compares with the apps that rank above it in search. Follow the steps in order. Show them a result before you suggest signing up for anything. ## 1. Start with the user's brief From what the person already said, find: - **The app.** You need its numeric App Store id: the digits after `id` in its URL, for example `6760958090` in `https://apps.apple.com/us/app/nommie-ai-calorie-tracker/id6760958090`. If you have only the name, find the URL with your search tool, or ask for the link. - **Up to 3 search keywords** people type to find apps like theirs, for example `calorie tracker, ai calorie counter, food diary`. If none were given, propose 3 from the app's category and ask the person to confirm or edit them. - **The storefront** (two-letter country code). Default `us`. ## 2. Use the tools you already have - No account, API key or install is needed. One HTTPS GET returns everything. - Use your own HTTP fetch tool. If you have a shell, `curl` works. - The data comes from Apple's public search and lookup APIs. Do not scrape the App Store website. - If you can open images, look at the screenshot URLs (section 6). If you cannot, say so; do not describe screenshots you have not seen. - If the person is signed in to BrandBeacon and you have the BrandBeacon MCP server or a v1 API key, see section 8. ## 3. Run the benchmark ```bash curl -s "https://brandbeacon.dev/api/public/app-store/benchmark?app_id=6760958090&keywords=calorie%20tracker,ai%20calorie%20counter,food%20diary&country=us" ``` URL-encode spaces (`%20`) and separate keywords with commas. More than 3 keywords is refused; make a second request for more. The response, shortened: ```json { "app_id": "6760958090", "country": "us", "checked_at": "2026-10-10T18:00:00.000Z", "status": "ok", "app": { "found": true, "name": "Nommie - AI Calorie Tracker", "rating": 4.67, "rating_count": 122, "version": "1.5.5", "store_url": "https://apps.apple.com/us/app/...", "screenshots": [ "https://is1-ssl.mzstatic.com/.../01_home.png/320x480bb.jpg", "...", "..." ], "screenshots_source": "lookup" }, "keywords": [ { "keyword": "calorie tracker", "status": "ok", "our_rank": 11, "our_rank_status": "ranked", "results_count": 12, "top_competitors": [ { "rank": 1, "app_id": 341232718, "name": "MyFitnessPal: Calorie Counter", "seller": "MyFitnessPal, Inc.", "rating": 4.71, "rating_count": 2375258, "screenshots": ["...", "...", "..."], "store_url": "..." } ] } ], "errors": [], "search_depth": 15 } ``` ## 4. API quick reference | Item | Value | | ------------ | --------------------------------------------------------------------------------------- | | Endpoint | `GET https://brandbeacon.dev/api/public/app-store/benchmark` | | Auth | None | | `app_id` | Required. Numeric App Store id | | `keywords` | Required. 1 to 3, comma-separated, each at most 100 characters | | `country` | Optional. Two-letter storefront code, default `us` | | Rate limit | 5 requests per minute and 50 per day, per IP address | | Time | Usually 1 to 4 seconds; each Apple call gives up after 6 seconds | | Search depth | The top 15 results per keyword, in Apple's order | | Per keyword | `our_rank`, `our_rank_status`, `results_count`, `top_competitors` (5, our app excluded) | | Per app | `rank`, `name`, `seller`, `rating` (2 decimals), `rating_count`, first 3 `screenshots` | | Our app | `name`, `rating`, `rating_count`, `version`, `store_url`, first 3 `screenshots` | `our_rank_status`: `ranked` (`our_rank` is 1 to 15), `not_in_top_15` (`our_rank` is null), or `unknown` (the search failed, `our_rank` is null; the reason is in `errors[]`). `status`: `ok` (everything read), `partial` (a keyword or the app lookup failed), `failed` (every keyword failed, HTTP 502). ## 5. When something fails | What you see | Meaning | What to do | | ------------------------------------------------- | ------------------------------------------------------- | ---------------------------------------------------------------------- | | HTTP 400 `invalid_app_id` | `app_id` is not numeric | Take the digits after `id` in the app's URL | | HTTP 400 `missing_keywords` / `too_many_keywords` | 0 or more than 3 keywords | Send 1 to 3. Ask the person which 3 matter most | | HTTP 400 `invalid_country` | Not a two-letter code | Use `us`, `gb`, `de`, ... | | HTTP 404 `app_not_found` | Apple has no app with that id in that storefront | Check the id and the country with the person | | HTTP 429 `rate_limited` | Over 5 per minute or 50 per day from your IP | Wait the `Retry-After` seconds. Do not loop | | HTTP 503 `rate_limiter_unavailable` | Our limiter is down; nothing was checked | Retry once after a minute | | HTTP 502 with `status: "failed"` | Apple's search did not answer for any keyword | Retry once after a minute, then tell the person Apple is not answering | | HTTP 200, `status: "partial"` | Some keywords or the app lookup failed (see `errors[]`) | Report what was read; mark the failed keywords "unknown" | | A keyword with `our_rank_status: "unknown"` | Its search failed | Say "unknown". Never say "not in the top 15" for it | | `app.version` or `app.rating` is null | Apple did not send it | Say "unknown", never 0 | | `app.screenshots` is empty | Apple returned none for this app and storefront | Say so (see `app.note`); compare on ratings and ranks only | ## 6. Present the result Use this shape (the values below are an example, not data): ``` Nommie - AI Calorie Tracker: 4.67 stars from 122 ratings, version 1.5.5 (App Store US, checked 2026-10-10) | Keyword | Your rank | Top app (rating, ratings) | | calorie tracker | 11 of 15 | MyFitnessPal (4.71, 2,375,258) | | ai calorie counter | not in top 15 | Cal AI (4.80, 369,362) | | food diary | unknown (search failed) | - | Your first 3 screenshots vs the top apps: - Yours: 1) home screen 2) camera scan 3) meal plan - Top apps: 4 of 5 open with a benefit headline over a single feature; 3 of 5 show a number (calories, weight) in screenshot 1. 3 suggestions: 1. ... 2. ... 3. ... ``` Rules: - Ranks: "N of 15" when ranked, "not in top 15" when `not_in_top_15`, "unknown" when the search failed. Never fill in a missing value. - Screenshots: open the first 3 of ours and of the top 5 for each keyword if you can view images. Describe what they show (headline text, the feature shown, people, numbers, device frames, colours). Count patterns across apps ("4 of 5 ..."). If you cannot view images, say so and do not describe them. - Suggestions: exactly 3, each tied to something the top apps show and ours does not, naming the apps (for example "MyFitnessPal and Cal AI lead with the result, a calorie number, in screenshot 1; ours leads with the home screen"). No generic advice that the data does not support. - Ratings are evidence too: a big gap in `rating_count` means the top apps win on reviews, which screenshots alone will not fix. Say so if it applies. ## 7. Next step and handoff New screenshots should be tested, not guessed: Apple's product page optimization runs A/B tests on real App Store traffic. Hand off with this line: > Connect App Store Connect in BrandBeacon to A/B test new screenshots: > https://brandbeacon.dev/auth?mode=signup Signing up and connecting App Store Connect need the person. Do not create accounts, enter passwords or upload anything for them. ## 8. Signed-in users: MCP server and v1 API BrandBeacon users can run the same scan on their registered apps and manage screenshot sets and A/B tests from their agent: - MCP server: `POST https://brandbeacon.dev/api/mcp` (Streamable HTTP) with `Authorization: Bearer bb_live_...`. Tools include `bb_store_competitor_scan(brand_id, app_id, keywords?, country?)`, `bb_store_sets_list`, `bb_store_listing_test_create` and `bb_store_listing_tests_list`. - v1 REST: `GET https://brandbeacon.dev/api/v1/brands/{brand_id}/store-listing/apps/{app_id}/competitors` with the same key. - The person creates an API key in BrandBeacon under Settings > API Keys. Ask them for the key. Never ask for their password. - Full API reference: https://brandbeacon.dev/llms-full.txt
