Related Posts Shopify Apps — Frequently Asked Questions
1. Which related posts app has the highest market share on Shopify?
SEOWILL: AI SEO & AI Blog Post ranks #1 by share among related posts apps at 85.4%, but the market is fragmented — multiple apps capture meaningful share. Compare the top 5 on features and pricing before deciding.
2. How is market share calculated for related posts Shopify apps?
For related posts (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.

6. How many related posts apps does ShopDigest track on Shopify?
ShopDigest tracks 96 related posts 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 related posts app differ from the #1 ranked app?
Rank reflects an app's current position in the Shopify App Store under related posts (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.
