We audited Sample Store across 5 pages and 20 checkpoints covering speed, search visibility, and conversion trust signals. We found 2 critical issues, 3 warnings, and 3 further opportunities — alongside 12 checks the store already passes.
The five highest-impact fixes are listed in the action plan below. Most are theme-level changes a developer can complete in under a day total.
Measured with Google Lighthouse on a simulated mid-range phone — the same methodology Google uses for ranking signals.
Example: 25Q2_BAU_Site_MenApparel-Tile_Desktop_2x3_a33afc6a-0d4a-4ff6 is 1134 KB and not served as WebP/AVIF. On a phone over LTE this single image can take seconds. Images are the #1 cause of slow store pages.
How to fix: Serve responsive sizes (srcset), compress to WebP/AVIF, and keep hero images under ~200 KB.
Largest Contentful Paint is 19.9s on a simulated mid-range phone — Google's "poor" threshold is 4.0s and its ranking systems use this number. Shoppers on phones are staring at an incomplete page for ~19.9 seconds.
How to fix: Compress/resize the hero image, preload it, and cut render-blocking scripts. This is usually the single highest-impact fix.
Heavy HTML usually means inlined app code or huge menus; it delays everything that comes after it.
How to fix: Audit installed apps and theme sections; remove what you no longer use.
Total Blocking Time measures how long taps/scrolls go unresponsive while scripts run — usually app scripts.
How to fix: Remove or defer heavy third-party scripts; load chat/review widgets after interaction.
Alt text is how Google Images indexes your products (a real discovery channel for e-commerce) and how screen-reader users shop your store.
How to fix: Add descriptive alt text to product and lifestyle images: "{product name} – {key attribute}".
Estimated saving ≈ 1.9s on mobile (homepage).

Multiple H1s dilute the topical signal of the page.
How to fix: Keep the hero headline as the only H1; demote the rest to H2.
