Before using any benchmark to set expectations, it helps to understand where the numbers come from and what they can — and cannot — tell you.
The figures in this guide draw from three sources: patterns observed across SEO campaigns we've managed for architecture and professional services firms, published data from third-party tools including Google Search Console benchmarks, BrightLocal's annual local search reports, and Semrush industry studies, and publicly available conversion research from HubSpot and Demand Gen Report covering B2B professional services.
Where we cite a range rather than a single number, that range reflects genuine variation across firm types, market sizes, and service mixes. A boutique residential firm in a mid-size market will see different numbers than a commercial architecture practice in a major metro competing against established brands with decade-old domains.
What these benchmarks are good for:
- Setting realistic expectations before committing to an SEO budget
- Identifying which metrics to track and in what sequence
- Benchmarking your current performance against typical starting points
- Building an internal business case for organic search investment
What they cannot do: guarantee outcomes for your specific firm, replace a proper audit of your current site and market, or substitute for a strategy built around your actual competitive landscape.
Treat every figure here as a directional target. The disclaimer that applies throughout this page: benchmarks vary significantly by market, firm size, specialty, and starting domain authority.
