It’s rare that another SEO app conflicts with JSON-LD for SEO, so that’s not usually a concern I have. There are lots of JSON-LD for SEO customers who use other SEO apps.
Despite what other apps or SEO consultants say, having more than one set of product data is normal and a common misconception that there should be only one. Google Search will pick the best set of data to use for its analysis. That’ll be the set from JSON-LD for SEO. They’ll ignore the other Product data.
I’ve found over time that Shopify is adding to the platform many of the core features found in most Shopify SEO apps. So the apps have been adding features that aren’t all that effective or helpful, more buzzwordy. At best they are automation tools to get ‘okay’ results, at worst they’ll hurt your SEO.
I have a large guide on Shopify SEO with a ton of details on how to improve your SEO without using another app in Shopify. If you specifically scroll down to the Shopify SEO Apps section, I also mention SEO tools outside of Shopify that don’t impact your site load times.
I just have a hard time with monthly costs when most of the features are built into Shopify directly.
