The verdict in three sentences
Ranking first on Google is no longer enough: what counts is the click rate on your link. Schema.org structured data in JSON-LD surfaces review stars, prices, stock and questions straight into the results, which can lift CTR by 20 to 35% at the same position. In Senegal in 2026, it is one of the cheapest and most underused SEO levers.
Which schemas for which rich result
Each schema type unlocks a specific display in the SERPs (results pages). Here are the most profitable for a local SME:
| Schema type | Rich result unlocked | Estimated CTR gain |
|---|---|---|
| Product + Offer + AggregateRating | Price, stock, stars | +25 to +35% |
| Review / AggregateRating | Stars in the snippet | +20 to +30% |
| FAQPage | Expandable questions under the link | +15 to +25% |
| BreadcrumbList | Readable breadcrumb trail | +5 to +10% |
| Event | Date, venue, ticketing | +20 to +30% |
| LocalBusiness | Hours, map, phone | Local baseline |
| HowTo / Article | Steps, image, author | +10 to +15% |
Eligibility is never guaranteed: Google decides whether to show the snippet. But without the markup, you have no chance of appearing enhanced.
The JSON-LD mistakes that lose rich results
Most markup fails validation for avoidable reasons. Here are the classic traps and their fixes:
| Common mistake | Consequence | Fix |
|---|---|---|
| Rating without visible reviews on the page | Penalty / snippet refused | Show real reviews |
| Price in schema ≠ displayed price | Snippet ignored | Sync the values |
| FAQPage with promotional content | Non-compliance | Real Q&A |
| Missing required fields (image, name) | Not eligible | Complete the schema |
| Multiple conflicting LocalBusiness | Google confusion | One coherent block |
Always validate with Google's Rich Results Test and Search Console (the "Enhancements" report). Markup that passes the test is not yet shown, but markup that fails never will be.

Mini case study
Moussa runs an online hardware store in Dakar. His "drill" product page ranked 3rd on Google with a 6% CTR. After adding Product + Offer + AggregateRating schema (4.6 stars, 23 real reviews, price 38,500 FCFA, "in stock"), Google shows the stars and price in the result. CTR climbs to 8.1%, i.e. +35%. Out of 4,000 monthly impressions, he goes from 240 to 324 clicks, about 84 extra qualified visitors per month, without moving from 3rd place or paying for ads.
FAQ
Does structured data improve my ranking? Not directly: it does not raise your position, but it boosts click rate (up to +35%), which sends Google a positive engagement signal that helps over time.
JSON-LD or microdata? Google explicitly recommends JSON-LD: it sits in a separate script block, is easy to maintain and does not clutter your visible HTML. It is the 2026 standard.
How long before the stars appear? After validation, expect generally a few days to 3-4 weeks, the time for Google to recrawl and decide to show the rich snippet.
Can I invent reviews to get the stars? No, that violates Google's guidelines and can trigger a manual action. Reviews must be real and visible on the marked-up page.
Which schemas to prioritize for a local Dakar business? Start with LocalBusiness (baseline), then Product/Offer if you sell online, FAQPage for your service pages and Review to display your stars. It is the best effort-to-gain combination.
