What we learned fixing 325+ stores.
Practical write-ups from the Blinc team. Speed, migrations, Shopify Plus, checkout, and how we work with agencies. Every post ends with something you can do this week, and most of them have a tool you can use right now.

Written by the people who do the work.
Not a content team. The developers and the founder who fix these stores every week write these posts between builds. That is why they are short and why they have numbers in them.
- Every post has a check you can run yourselfUsually under five minutes, usually in the Shopify admin or a browser tab. Most posts also carry a calculator or checklist built for that job.
- We show the mistake, not just the fixIf we name a pattern, it is because we have removed it from a real store, more than once.
- No affiliate links, no app roundupsWhen we recommend a tool it is because we install it for clients and get the support tickets after.
