2. App Store SEO Checklist - iOS & Android
STEP 1: META DATA
1) Define target audience keywords
Use plural forms whenever possible
Longer phrase vs. many keywords
Avoid articles and prepositions, if possible ("a" "the" "and" are ignored, but content too SPAMMY
will cause Apple to reject)
2) Mobile App Title Longer phrase beats one-off keyword here, but iOS search visibility is now much smaller
3) App Description
Above the fold, 2 sentences w/ consistency in keywords, don't forget plurals
4) Optimize URL
5) Create Keyword Field (max 100 characters)
When choosing your keywords, just like on the web, focus on relevancy, search volume, and
difficulty.
Don't use multiple word phrases; break out to individual words (Apple can combine them for you).
Don't repeat keywords that are already in your title
(put the most important ones in your title, leaving the keyword field for your secondary keywords).
Separate keywords with commas, and don't use spaces anywhere.
6) Avoid mixing publisher name (unfunnel) with keywords (rewards)
User who searches "unfunnel rewards" will not see a result for your app
7) Choose the Right App Category
8) Separate Keywords with commas

3. STEP 2: OFF-STORE SEO
1) Rating Quality (esp in iOS)
2) Build inbound links to the App's URL
3) Encourage User Reviews
4) External Review sites

4. App Store Optimization - Imagery & UX
1) Screenshot in SERP:
Does the visual tell the user what the mobile app does?
Readable when scaled down to ~200pt?
Social sharing functionality - i.e., Facebook "Like" Button
2) Include multiple screenshots & Video Trailer (when possible)
3) Icon - scale, simplicity, brand consistency
