The verdict in three sentences
Schema markup (structured data in JSON-LD) describes your content to Google to trigger rich snippets: review stars, price, expandable FAQ, breadcrumb. Done right, it lifts click-through rate by 20 to 30 % without gaining a single ranking position. It is one of the most cost-effective SEO levers in 2026: a few lines of code, no recurring cost, a direct effect on SERP visibility.
Schema types by sector
Each page type has its priority schema. Here are the useful mappings for Senegal in 2026.
| Sector | Priority schema | Target rich result | Estimated CTR impact |
|---|---|---|---|
| Restaurant | LocalBusiness + Menu | hours, reviews, menu | +20 to 30 % |
| E-commerce | Product + Offer + Review | price, stock, stars | +20 to 35 % |
| Clinic / health | LocalBusiness + MedicalOrg | address, hours, reviews | +15 to 25 % |
| Blog / media | Article + BreadcrumbList | date, author, breadcrumb | +10 to 20 % |
| FAQ page | FAQPage | expandable questions | +15 to 30 % |
| Hotel | Hotel + AggregateRating | rating, price, availability | +20 to 30 % |
| Event | Event | date, venue, tickets | +15 to 25 % |
FAQPage and Product are the most rewarding: they take more space in the SERP and capture the click ahead of competitors.
Common errors and validation
Badly placed schema is ignored — or even penalized. 2026 checkpoints.
| Error | Consequence | Fix |
|---|---|---|
| Invalid JSON-LD (syntax) | rich result not shown | validate with Rich Results Test |
| Data not visible on page | Google non-compliance | markup must mirror visible content |
| Fake reviews / false AggregateRating | manual penalty risk | only show real reviews |
| Wrong type | eligibility refused | pick the official schema.org type |
| Missing required fields | partial snippet | fill name, price, ratingValue... |
| Duplicate schema | crawler confusion | one coherent block per entity |

Mini case study
Ibrahim runs a restaurant in Abidjan with 1,200 impressions/month on his listing and a 4 % click-through rate, i.e. 48 clicks. By adding LocalBusiness + AggregateRating schema (real reviews, 4.6 rating), his snippet shows stars and his CTR rises to 5.2 %: 62 clicks/month, i.e. +14 visits without spending a franc on ads. Over a year that is ~170 extra visits for a few lines of JSON-LD.
FAQ
Does schema markup improve my ranking? Not directly, but it boosts click-through rate by 20 to 30 % via rich snippets, sending a positive engagement signal. At equal position, a marked-up page captures more clicks than a bare one.
JSON-LD or microdata? Google recommends JSON-LD: injected in a separate script block, easier to maintain than microdata mixed into HTML. It is the 2026 standard.
Can I add fake ratings to get stars? No: AggregateRating must reflect real reviews visible on the page, or you risk a Google manual penalty. Twelve real reviews at 4.6 beat an invented rating.
How do I check it works? Run the URL through Google's Rich Results Test, then track the Search Console Enhancements report. Rich results usually appear within a few days to two weeks after indexing.
