Extension Architecture in London currently sits at 11.6K monthly organic traffic, 8K ranking keywords, 1.5K referring domains and an authority score of 31. Google's AI Overview cites the firm directly.
That took years, not a quarter. The relationship started in 2016, which is the least marketable and most important fact in this article.
Their own summary of the decade:
"We've worked with Nik since 2016, and his SEO and Google Ads strategies have consistently generated quality enquiries for our business. As search evolved, he also helped us strengthen our visibility across AI-powered search, keeping us ahead of the competition." Eugene Kim, Extension Architecture
What follows is the sequence that produces numbers like those, drawn from how SEO for architect firms actually gets built rather than how it gets pitched.
Architecture Firms Lose Projects At The Portfolio Page, Not The Homepage
The first structural problem in almost every studio site is the portfolio.
Galleries are image heavy by definition, and image heavy pages load slowly, compress badly and carry almost no text for a search engine to read. A stunning project page with no alt structure, no schema and a four second render on mobile is invisible in exactly the moment it matters.
The fix is unglamorous. Compress and tag the galleries properly, add structured data that states what kind of firm you are and what kind of projects you run, and turn each completed project into a page that ranks for its own search terms rather than sitting inside one long scroll.
That last point is where most practices leave money. A completed loft conversion in Islington is a searchable thing. Buried in a gallery, it is nothing.
Residential And Commercial Enquiries Need Separate Paths
A homeowner and a developer are not the same buyer, and they should not land on the same page.
Homeowners search differently, decide faster, and care about planning permission and cost. Developers run longer cycles, care about delivery capability and precedent, and often arrive via a completely different keyword set. Commercial work involves institutional clients on timelines residential work never sees.
Site architecture should reflect that split. Separate service paths, pages organised by project type and budget range instead of vague service lists, and fewer clicks between a visitor and a brief request.
Worth saying plainly: this single change often lifts enquiry quality more than any ranking improvement, because you stop attracting the wrong brief.
Regional Pages Matter More Than National Rankings For Studios
Most architect searches carry local intent. "Architect in Manchester" and "architects near me" are the queries that convert.
That makes local visibility the fastest available win for most practices. Consistent listings across architecture directories and local platforms, a maintained Google Business Profile, and genuine pages for every market you actually take projects in.
There is a useful proof point here from an adjacent account. A multi city structural engineering campaign reached top three local pack positions across 18 target UK cities within six months. Different discipline, same mechanism, and a faster timeline than national organic ranking typically allows.
Planning and permit content sits in the same layer. Guides answering what clients genuinely search before hiring, permitted development limits, listed building consent, party wall procedure, pull in exactly the people about to commission work.
Authority For Architects Comes From Design Press, Not Generic Links
This is where architecture SEO diverges sharply from a generic SEO Company playbook.
Links from design publications with real standing in the sector carry weight that directory submissions never will. Coverage on the outlets architects actually read, award recognitions turned into citable proof points on your own site, and links from contractors, developers and industry associations you already work with.
The last one is routinely ignored. Most practices have existing relationships with builders, engineers and suppliers who would happily link to a project they collaborated on. Nobody asks.
Not Every Architecture Account Produces A Headline Number
Here is the part most agency content leaves out.
London Design and Build, also in London, shows organic traffic up 12 per cent to 281 visits a month, with 344 ranking keywords, 1.4K backlinks and early AI citations on ChatGPT and AI Mode. That is a different scale entirely from Extension Architecture's 11.6K.
Both are real accounts with the same team and the same disciplines. The difference is starting position, domain age and how long the work has compounded. Their view of it:
"Big Hunt Digital has helped us generate a steady flow of qualified enquiries through AI-powered SEO and Google Ads. They understand our industry, communicate clearly, and focus on delivering genuine business opportunities instead of vanity metrics." Youno, London Design and Build
Big Hunt's architecture page cites an average 430 per cent organic traffic lift over twelve months alongside 1,200+ ranking design keywords, and states three or more architecture studios served. Small sample, and the honest reading is that the range between accounts is wide.
If an agency shows you only their best account, ask for their most ordinary one.
AI Search Is Reshaping How Clients Shortlist Studios
Prospective clients now ask ChatGPT and Perplexity to recommend architects before they open a search results page, and AI Overviews often answers first.
Extension Architecture being cited directly in AI Overview is the outcome that matters here, and it did not come from a separate AI project. It came from the same technical foundation, clean schema, entity clarity, and years of genuine third party mentions the models can verify.
Run the test on your own practice tonight. Ask ChatGPT to recommend architecture studios in your city, then check whether your name appears and how you are described. Most principals have never looked.
What A Realistic First Six Months Looks Like For A Practice
Months one and two go on diagnosis and structural repair. Crawl health, orphaned project pages, portfolio speed, mobile gallery performance, click to enquire on every project page, schema across the site.
Months three and four build the missing pages. Project case studies, service type paths, regional pages, planning content.
Months five and six are authority and measurement. Outreach to design press and trade partners, award submissions written up properly, and the first meaningful ranking movement from the technical work shipped back in month one.
The pipeline figures Big Hunt publishes for this vertical, 122 project inquiries with 55 reaching qualified status and 3x ROI, describe a mature account rather than a starting one. Treat them as direction of travel.
The Metric Architecture Firms Should Actually Track
Not traffic. Briefs received, split by project type and budget band.
A practice receiving four residential enquiries a month at £80K project value has a different business than one receiving one commercial enquiry at £900K. The same traffic number can produce either, which is why traffic alone tells a principal nothing useful.
Track briefs, track which pages produced them, and track how many turned into fee proposals. Everything else is diagnostic.
Ten years of compounding is what produced the Extension Architecture numbers. There is no version of this that works in eight weeks, and any agency saying otherwise has not worked in this sector.
