Delta Surveillance
Delta Surveillance installs CCTV and security systems in London. The site carries LocalBusiness markup alongside a separate Service node for each thing the company installs, plus FAQPage structured data built from the questions customers actually ask before committing to a security install.

The problem
Security installation is a considered purchase made by people who do not know the vocabulary. They search for the problem rather than the product, and they want their questions answered before they will give anyone their phone number, which makes a page of marketing copy almost useless.
What we built
- A Service node per offering, so each installation type can be understood and ranked separately
- FAQPage markup built from genuine pre-sale questions, eligible to appear directly in search results
- LocalBusiness structured data with opening hours, coordinates and postal address
- PropertyValue markup for the specification details that buyers compare between installers
They search for the problem, not the product
Someone wanting cameras does not search for the model. They search for the worry - a break-in nearby, a delivery going missing, a business insurer asking for coverage. Pages that answer those questions get found; pages describing product lines do not.
So the structured data treats each offering as its own Service rather than lumping them into one
page about what the company does.
Questions before contact details
Nobody books a security survey without first wanting to know what it costs, how long it takes,
whether it needs planning permission and what happens if it breaks. Those questions are marked up
as FAQPage entries, which makes them eligible to be shown directly in search results and quotable
by an AI assistant.
Honest note
This is a React application, and at the time of writing it ships more to the browser than the other sites on this page. The structured data work here is the strongest part of the build; the payload is the part we would revisit.
