Serrurier Paris Express: a locksmith site that leads with the price

Someone searching for a locksmith in an emergency decides fast, under stress, in a trade known for surprise bills. The usual answers — badges, star widgets, “cheapest in Paris” — are exactly what make people suspicious. The site had to earn trust with something the customer can check.

So the headline is the thesis: “Serrurier à Paris : le prix d'abord, l'outil ensuite” — the price first, the tools second. Service pages show their price, the full grid is public on the pricing page, and the copy repeats one promise the artisan can keep: the price is agreed by phone and confirmed in writing before any work starts.

The price grid lives in one file and feeds every page that shows a price, so a change is made once. Prices are stored including VAT, the pre-tax figure is derived from them, and they are rounded up to the nearest ten, never down.

The figures started from a market reference grid the client supplied, and they were challenged where they did not hold: an €80 door-reinforcement price that contradicted market evidence was reopened and corrected to €1,070 including VAT before launch. A price grid is only a trust signal if it survives a customer's comparison.

The site is in French and English, with 68 pages in each: seven services (five for households, two for businesses — securing commercial premises and maintenance contracts), five emergency pages written around what people actually type, five guides, and 41 location pages, plus pricing, quote, contact, about and legal pages.

The location pages follow a hub structure — the 20 Paris arrondissements, the seven Île-de-France départements and eight nearby towns — with real local references on each page rather than one template with the name swapped. Six pages for other French cities are explicitly labelled as covered through a network, so the site never implies the Paris artisan travels there. Pages are prerendered to static HTML; the only server code is the form endpoint.

The quote form posts to a single server route that emails the request through Resend to the artisan, with a monitored copy. The customer's confirmation email is sent only once the team's copy has gone out, so nobody is told “we received your request” when nobody did. After submitting, the customer is offered WhatsApp as a faster channel — offered, not forced.

At the client's request the form has no CAPTCHA; it is protected instead by a hidden honeypot field, a same-origin check, a limit of 15 requests per minute per IP address and a cap of three emails per hour per recipient. A postcode check tells visitors straight away whether they are in Paris, in Île-de-France or outside the zone, and a “use my position” button finds the address through IGN's Géoplateforme, the French national mapping service; the position is used once and not stored.

Every page carries structured data: a Locksmith business entity, each service with its price as an Offer, FAQ answers and breadcrumbs, plus a sitemap with French and English alternates. The robots file explicitly allows AI crawlers such as GPTBot, ClaudeBot and PerplexityBot, so an assistant asked what a locksmith costs in Paris can read the real grid.

What the structured data leaves out matters as much: there is no AggregateRating and no review markup, because there are no verified reviews yet — and the reviews section on the page says exactly that instead of filling the space.

Eight conversion events are wired — call clicks, WhatsApp clicks, form submissions, location lookups and others — and they fire only after the visitor accepts cookies, in line with CNIL rules. The tag manager is not connected yet, so nothing is collected today; when it is, the events are already in place.

No invented reviews, no rating stars without ratings, no “cheapest in Paris”. Legal details the business has not supplied yet are shown as pending rather than filled with plausible-looking numbers.

When the client asked to soften the anti-scam tone of the marketing copy, the guides kept their practical advice on avoiding locksmith scams. That content is there to help the reader, not to sell.

For a local service business, the most persuasive thing a website can show is what competitors hide. Here it is the price. Publishing it forces the rest of the system to be honest: the grid has to be defensible, the written quote has to match it, and the form has to reach a real person.

That is also why the build started from content and structure — services, emergencies, locations, prices — before visuals. Pages that answer one specific question are the pages search engines and AI assistants send people to.
