Robots.Txt Shopify Apps — Frequently Asked Questions
1. Which robots.txt app has the highest market share on Shopify?
GPTLab: ChatGPT Claude AEO SEO ranks #1 by share among robots.txt apps at 49.0%, 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 robots.txt Shopify apps?
For robots.txt (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 robots.txt apps are gaining market share on Shopify?
GPTLab: ChatGPT Claude AEO SEO is gaining robots.txt app market share fastest this month, up +48.50pp versus 30 days ago. Switch the table sub-tab to "Market Share Changes" to see all gainers ordered by movement.
4. Which robots.txt apps are losing market share on Shopify?
SEOWILL: AI SEO & AI Blog Post has lost the most market share this month among robots.txt apps (-0.75pp). Sort the table by Change (Low to High) to see the full list of decliners.
5. Which countries drive the most robots.txt Shopify app installs?
United States drives the largest share of robots.txt app installs at 35.5%, followed by United Kingdom at 9.2% and India at 7.0%. Use the country picker on the third card to compare market leaders by country.
6. How many robots.txt apps does ShopDigest track on Shopify?
ShopDigest tracks 95 robots.txt 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 robots.txt app differ from the #1 ranked app?
Rank reflects an app's current position in the Shopify App Store under robots.txt (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 robots.txt, GPTLab: ChatGPT Claude AEO SEO leads on share; see the rankings tab for who currently holds #1 position.
