The Short Answer
A common, reasonable benchmark is 5-10% of gross revenue for an established Ottawa firm, with newer or growth-focused firms sometimes justifying a higher percentage temporarily to build initial momentum. The specific number matters less than making sure the budget is actually allocated deliberately across channels rather than spent reactively on whatever a salesperson pitched most recently.
How to Allocate the Budget Across Channels
A balanced allocation typically includes a foundation layer (website, SEO, content — the assets that keep working without ongoing per-click spend), a paid layer (Google Ads and Meta ads for immediate visibility), and a relationship layer (referral program development, community involvement). Firms that pour their entire budget into paid ads alone are renting all their visibility with nothing compounding over time.
For an Ottawa firm specifically, it's worth deliberately budgeting for underserved-opportunity content — federal-employment, bilingual, and Kanata-tech-sector-focused pages — since the competitive cost to establish authority in these specific niches is currently lower than in oversaturated general practice-area terms.

Adjusting the Number Based on Firm Stage
A newer Ottawa firm building initial visibility often justifies temporarily allocating more toward the foundation and paid layers to establish presence faster, then shifting the mix toward relationship-building and content as referral flow and organic authority build over time. Whatever the split, tracking ROI by channel is what actually tells you whether the allocation is working, rather than guessing based on industry benchmarks alone.
A marketing budget without a deliberate allocation isn't a strategy — it's just spending. The number matters less than knowing exactly what each dollar is supposed to accomplish.
