How to Choose Between Architects SEO Companies and a General SEO Agency

At some point every practice that wants more enquiries from search runs into the same fork. Do you go with one of the architects seo companies that only works with architecture firms, or with a general agency that has a long client list across every industry you can think of? Both sell the same word, SEO. They don't always deliver the same thing.

There's no universal right answer, which is annoying, but there are some fairly clear signs about which one suits which kind of practice. Here's how we'd think it through, with one caveat up front: we run one of the specialist agencies ourselves, so weigh our view accordingly.

What a Specialist Brings

The biggest advantage of a specialist is that they already know how your clients behave. They know a homeowner thinking about a rear extension doesn't search for "architect" on a whim. They search for permitted development limits, Article 4 directions and how long a council takes to decide, often for weeks before contacting anyone. A specialist builds pages around those questions without needing it explained.

They'll also know the content that works. Project pages that name the property type, the planning route and the outcome. Borough pages that reflect real local rules. A Google Business Profile that's updated with actual project activity. That knowledge saves you months of explaining your own industry to someone who's learning it on your budget.

The trade-off is narrowness. A specialist may have a fixed way of working, and it may not fit a practice that does something unusual, like heritage work, large commercial schemes or a very specific regional niche. You're also relying on their pool of examples, which can be thin if they're a small outfit.

What a General Agency Brings

A general agency usually has broader capability under one roof: technical SEO, web development, paid search, content, reporting. If your website is a mess, or you need a rebuild and ads running alongside the SEO, one team handling all of it can be convenient. Larger agencies also tend to have more process and more people to cover absences.

The weakness is exactly the opposite of the specialist's. They may treat your practice like any other local service business and run the same checklist they'd use for a dentist or a plumber. Keyword lists, a few blog posts, some citations, a monthly report. None of that is wrong, but it often misses what makes architecture searches different, and the budget goes on activity instead of the questions your clients actually ask.

Where the Line Actually Falls

It helps to ask what your biggest problem is right now. If it's that nobody who's ready to hire finds you, and your work isn't showing up for planning-stage searches, a specialist is usually the better fit. That's a content and local visibility problem, and it rewards industry knowledge.

If instead your site is slow, broken on phones, or built in a way that stops search engines reading it, you've got a technical problem first. A regular SEO agency with solid technical and development skills may be the more sensible starting point, as long as they're willing to learn how your clients search and don't just apply a template.

Plenty of practices need both at different times. Some begin with technical repair and move to specialised content later. Others do the reverse. It isn't a marriage.

What This Looked Like for One London Practice

Extension Architecture is a London firm that specialises in house extensions, conversions and new builds, and they've been a client of ours since early 2016. When they first came to us, impressions were flat, organic visitors barely moved from month to month, and they had almost no presence in AI answers. Enquiries were patchy, so the pipeline dried up between projects.

The first three months went roughly like this. Month one was technical: crawl errors fixed, the site sped up, schema added across every service and project page. Month two was content and structure, with service and project pages mapped to what people actually search for, linked properly to each other. Month three was authority work and the start of optimising for AI citations. Paid campaigns on high-intent extension searches ran alongside, to bring in leads while organic caught up.

Today their authority score sits at 31 and 148 pages are cited across AI platforms, including Google AI Overview, AI Mode, Gemini and ChatGPT.

The useful part for this question is where the specialist knowledge mattered. Month one's technical work would have been much the same for any business with a slow, messy site. Month two was different. Deciding which pages to build, around extension and conversion searches rather than generic "architect" terms, is exactly the judgement a template doesn't give you. If your main problem is technical, that's the general agency's home ground. If it's deciding what to say and to whom, specialist experience earns its keep.

Questions That Separate Good From Average

Whichever type you speak to, a handful of questions tells you quickly how they think.

Ask for an example from a business with a long, considered buying process, not a restaurant or a shop. Ask how they'd decide which pages to build first for your practice, and listen for whether the answer involves your actual boroughs and project types or just "keyword research". Ask how they measure success. If enquiries aren't in the answer, keep looking.

Ask what happens in the first three months in plain terms. A decent provider can tell you what gets fixed, what gets written and what gets measured. Be careful with anyone who talks only about strategy and never about tasks.

Ask who writes the content. Planning content written by someone who doesn't understand what permitted development actually covers can be quietly wrong, and wrong advice on a site like yours is a credibility problem, not just an SEO one.

Price Tells You Less Than You'd Think

It's tempting to assume the specialist costs more because they're a niche, or that the general agency is cheaper because of scale. Sometimes that's true. Often it isn't. What matters is what's inside the quote. Compare scope instead of the headline number: how many pages, what kind of content, what reporting, what term. Two proposals at the same price can hide very different amounts of real work.

Contract terms matter too. A long lock-in before you've seen any work is worth a second look with either type of provider.

A Sensible Way to Test Without Committing Big

If you're not sure, start small. A paid audit or a short initial project lets you see how a provider thinks before you commit to a long retainer. You'll learn a lot from what they notice about your site, how clearly they explain it, and whether they ask good questions back.

Pay attention to the audit itself. Does it mention things specific to architecture, like project documentation and local planning content? Or could it have been written for any business with a website? You'll know within a few pages.

Keeping Your Own Records

Whoever you choose, keep a simple log of where each enquiry came from. A single question on the contact form is enough. After a few months you'll have your own data, independent of any report, and it will tell you whether the arrangement is working. It also makes you a better client, because you can point to real enquiries when you talk to your provider.

So, a specialist if your gap is reaching homeowners who are mid-research, a general agency if the problem is technical or you need several services at once. Either can disappoint if they treat you as a template.
