Technical tutorial: how to add a real SEO counter (60 title / 160 description) under PrestaShop 8 meta fields without touching the DB or theme. Module code, field detection in V2 + legacy, MutationObserver for lazy tabs, color-coded CSS.
Real case: PS8 store with 1,800 SKUs audited its metas, installed Zeyvro Meta Counter and rewrote the 41 products with title >60. Result at 30 days: +25% organic clicks, +19.5% CTR. 11 person-hours invested. Full data.
PrestaShop 8’s native counter shows 128/512 — those are DB maxlengths, not SEO targets (60 title / 160 description). The trap: no one notices the problem until SERPs are audited one by one. How to measure whether it applies to you.
