DeepLumen: AI Sales & AEO

15% of gross, broad access, and they kept our data after uninstall

Uninstalled after three days. Jewelry is charged 15% — not on product price, on the whole order total including shipping, taxes and tips. Their attribution counted an order as theirs with no way to tell whether the customer came through an existing wholesale or store relationship. The app wants deep access — products, 60 days of orders, theme and pages, device data, owner contact details — from a company launched in May 2026 with no references to offer when asked. We raised all of this in writing; the reply answered none of it and just re-offered three free orders. They also say store data is deleted on uninstall, yet weeks later emailed that our pages were 'still recoverable' and would restore exactly as left. Uninstalling left dead code in our theme we had to remove ourselves.

After uninstalling DeepLumen, I discovered that my product pages had canonical URLs pointing to DeepLumen’s `/a/shop/` paths instead of their actual Shopify URLs. Those paths redirected back to the original product pages while the canonical tags continued pointing to the DeepLumen paths, creating a redirect-and-canonical loop with conflicting signals for Google. Important product pages were consequently not discoverable or indexed.

Uninstalling the app did not fully correct the problem. I had to manually remove DeepLumen’s canonical code and references from my Shopify theme and robots.txt, restore Shopify’s proper canonical URLs, and request indexing again through Google Search Console.

I do not believe this was intentional, but it is a serious technical issue. Even while the app is installed and running, it should not override a store’s existing SEO structure or replace valid canonical URLs. Canonical tags must identify the original public pages—not redirecting app paths that point back to those same pages.

The AI traffic I received appeared to be primarily training-related traffic, not meaningful search indexing or customer discovery. Losing visibility on major search engines is not an acceptable tradeoff for that traffic.

The DeepLumen team needs to investigate this thoroughly, stop the app from interfering with canonical URLs and Google indexing, and ensure uninstalling removes all injected code and references. Until this is resolved, merchants should be warned that the app may significantly harm their organic search visibility.

We installed Deep Lumen 1 week ago, I thought all was well, but today I noticed an issue on one of our product pages. It was going to cartsure.top. They added Cartsure code onto the header and footer of our website to steal customer information. Luckily we caught it in time and spoke with a Shopify agent. Who instructed us delete the app and how to remove the coding. Moving forward we will be careful of what we download. I thought it could be trusted since it was an option in the Shopify App store.
