Custom Registration Shopify Apps — Frequently Asked Questions
1. Which custom registration app has the highest market share on Shopify?
UpPromote Affiliate Marketing currently holds the highest market share for custom registration apps at 71.9%, but the category is competitive — Affiliate Marketing ReferrLy is close behind at 13.2%. The right choice depends on your specific store needs.
2. How is market share calculated for custom registration Shopify apps?
For custom registration (a keyword page), market share is rank-weighted — apps at position #1 carry roughly 40× the weight of apps at position #22, and apps beyond #22 are excluded. Each app's weighted score is divided by the total weighted score across the keyword to give the share %. This reflects Shopify search behaviour: most installs come from the top of the results.
3. Which custom registration apps are gaining market share on Shopify?
Affiliate Marketing ReferrLy is gaining custom registration app market share fastest this month, up +6.02pp versus 30 days ago. Switch the table sub-tab to "Market Share Changes" to see all gainers ordered by movement.
4. Which custom registration apps are losing market share on Shopify?
Hulk Contact Form Builder has lost the most market share this month among custom registration apps (-12.60pp). Sort the table by Change (Low to High) to see the full list of decliners.
5. Which countries drive the most custom registration Shopify app installs?
United States drives the largest share of custom registration app installs at 42.7%, followed by United Kingdom at 8.6% and Germany at 7.8%. Use the country picker on the third card to compare market leaders by country.
6. How many custom registration apps does ShopDigest track on Shopify?
ShopDigest tracks 96 custom registration apps on the Shopify App Store. Market share, rankings, and review data refresh weekly so you can track competitive shifts as they happen.
7. Why does the highest-share custom registration app differ from the #1 ranked app?
Rank reflects an app's current position in the Shopify App Store under custom registration (driven by Shopify's own algorithm), while market share on ShopDigest is estimated from review counts and other factors as a proxy for active installs. The two metrics move on independent dynamics, so the highest-share app and the #1-ranked app are not always the same — and a divergence between them is worth noting rather than assuming one will pull the other along. For custom registration, UpPromote Affiliate Marketing leads on share; see the rankings tab for who currently holds #1 position.
