The client

Property diagnostics in France is a market where everyone searches for the same things: which diagnostics are mandatory, what they cost, how long they stay valid. The head query alone draws 27,100 searches a month. Diagnostics Immo started from nothing: no site, no brand, no history. The brief: a site designed to capture that market, not a brochure to fill in later. It is our website creation offer in its most complete form.

The problem

The competition here is large directories and national networks of certified diagnosticians. A brand-new site has no chance on the head term. So the strategy was architecture: one regulatory guide per diagnostic type, one local page per major city, and a quote comparison tool tying everything together and turning visits into leads. SEO was not added afterwards: it drew the site map.

Project roadmap

1
Week 1

Keyword research and architecture

Full market mapping: every diagnostic type, every sale-or-rental combination, every city where demand justifies a page. The site structure came out of that research, not out of a mockup. Regulation checked guide by guide.

2
Weeks 2-3

Design and regulatory content

Custom mobile-first design. The 34 regulatory guides cover obligations, validity periods, observed prices and penalties: the content visitors look for and Google rewards.

3
Weeks 3-4

Development and local pages

Custom-coded, fast, structured data on every guide. The 60 city pages each carry their own local context, avoiding the duplicate content that sinks programmatic sites.

4
