The 5 things that move the needle for building contractors
If you only had a fortnight to invest in your online presence, do these in this order.
Project portfolio (extensions, renovations, new builds, conversions)
Before/after photos of real projects. Categorise by type. 'House extension portfolio', 'Loft conversion before/after'.
Service-specific pages (extensions, renovations, new builds, conversions)
Each service gets its own URL. 'House extension builder [town]', 'Renovation contractor [town]'.
Building control + warranty badges
Insurance, NHBC, or LABC badges with links. Trust signal for high-value projects.
Transparent pricing + timeline examples
'Average 2-storey extension £40-80k, takes 4-6 months.' Sets expectations.
Before/after case studies with details
Include project scope, budget range, timeline, materials. Story-based = conversions.
What we see in the wild
Common builder-site SEO failures we find in real audits.
Portfolio missing or outdated. One generic 'Building Services' page. No insurance or warranty badges visible. Pricing missing (biggest hesitation for £50k+ decisions). No project timelines stated. Website looks cheap compared to competitors. Phone number or quote form buried.
What happens when you run a Flatline audit on a builder site
We score your homepage
Performance, on-page SEO, mobile, security, social, crawlability and structured data graded into a single Visibility Score 0-100.
You re-run on a service / specific page
Audit a service-specific page (treatment, menu, area). Service pages usually score 10-15 points lower than homepage — that's where the work is.
We surface the builder-specific gaps
Missing schema, no service-specific landing pages, NAP inconsistency, weak structured data — every finding is mapped to what a builder loses by ignoring it.
Track monthly
Re-audit on the 1st of every month. Watch the score climb as you ship fixes. Show the trend in budget conversations.
"After rebuilding our portfolio with case studies and adding transparent pricing, qualified enquiries increased 65% and close rate improved 25%."

Common questions
Should we publish indicative pricing by project scope?+
Yes. 'Single-storey extension £30-50k, two-storey £50-100k.' Removes guess-work anxiety.
How important is showing NHBC or LABC coverage?+
Critical. High-value projects need reassurance. Display badges prominently.
Should extensions and renovations have separate pages?+
Absolutely. Different search intent, different timelines, different customer profiles.
Is the score the same nationwide?+
Visibility Score itself is universal. What it predicts (rankings) varies by competition. A 70+ in a smaller town often means top of local pack. The same 70 in central London might still be page 2 — competition is the multiplier.
