Do I need a developer to act on this?
Not for most of it. Findings are tagged quick win or dev project, and the quick wins are usually copy and layout changes you can make in the theme editor in under an hour. The dev projects come with a written handoff so you can pass them on cleanly.
Will installing this slow my store down?
No. ShopGrade is a browser extension, not a Shopify app. Nothing is added to your storefront, the scan runs on your own machine, and your customers are unaffected either way.
Is my store data safe?
ShopGrade only reads your public storefront, the same pages any visitor sees. It has no access to your Shopify admin, so it cannot see orders, customers or payment information. It never reads form values or passwords, and it never writes to your store.
How is the score calculated?
The 0 to 100 score combines weighted checks across performance, page structure, script load, trust signals and SEO. Every finding shows the evidence behind it, so you can see what moved the score rather than taking the number on trust.
My score changed and I did not change anything. Why?
Scores are directional and measured live, so results vary with your connection, the device, third-party scripts loading differently and the state of the page at scan time. Treat a few points of movement as noise; treat a resolved finding as real progress.
Can I check a competitor's store?
Two ways. ShopGrade works on any publicly accessible Shopify storefront, so you can simply run the full audit on a rival and read the two reports side by side. Separately, on Pro and Agency you can type a competitor domain into the report’s own setup bar, and its Google chapter then carries a head-to-head benchmark: their Lighthouse performance score and lab LCP printed beside yours.
Can it watch my store between audits?
On Pro and Agency, yes. Add your store to weekly monitoring and ShopGrade re-checks it against Google PageSpeed every seven days, keeps the previous score beside the new one and emails you if it drops by five points or more. It is a light watch on the performance score rather than a full re-audit, so it costs no report generation. Run a rescan when you want the whole document again.
Can I change how strictly it grades?
Yes, on every plan including Free. The extension carries an audit recipe: a focus (balanced, speed, SEO or conversion) and a grading strictness. Pro and Agency add custom benchmarks, your own target score and target LCP. Whichever profile and targets produced a report are printed in its methodology chapter, so the conditions behind the grade are always on the page.
What do I get without paying?
Unlimited live scores on the toolbar, plus one report. It is owner-only and watermarked, and it is deliberately a sample of the real thing: you get the score, the verdict, the store health summary, the ten crawl and SEO checks and the page-weight breakdown. The conversion and trust signals, the ranked roadmap, the rollout plan, the implementation brief, the shopper timeline, the AI conversion review and its screenshots, the Google data, the business context and the technical appendix all show as locked, and it cannot be shared, emailed or exported.
What happens if I only fix some of it?
That is the normal case, and it is why the list is ranked. Work from the top, rescan, and the report tells you what actually moved rather than leaving you to guess.
