An accountant Google Ads budget should be based on client economics, search demand and conversion data rather than a generic monthly figure. A bookkeeping campaign, a contractor-accounting campaign and a tax-advisory campaign can have very different click costs, lead quality and client values.
Build the budget from the numbers that matter
Start with four inputs: expected cost per click, landing-page conversion rate, enquiry-to-client rate and expected client value.
Clicks = media budget ÷ CPC
Enquiries = clicks × landing-page conversion rate
New clients = enquiries × enquiry-to-client rate
Use your own account data as soon as it becomes available. Broad industry averages can hide major differences between services, locations and search intent.
Separate services instead of running one generic campaign
- Bookkeeping and monthly accounts
- Limited-company accounting
- Contractor accounting
- Ecommerce accounting
- Tax planning and advisory
- Payroll or VAT support
Each service should have its own economics and, where appropriate, its own landing page and keyword set. Someone searching for an ecommerce accountant has different needs from someone looking for help with a self-assessment return.
Budget for the full conversion journey
- Service-specific landing pages
- Call and form tracking
- CRM or source tracking
- Negative keyword management
- Fast lead routing and follow-up
- Ongoing search-term and lead-quality review
Sending every click to the homepage and measuring only form submissions makes it difficult to know which services and searches are actually producing worthwhile clients.
Use negative keywords aggressively
Accountancy searches can include jobs, courses, software support, free templates and general tax questions. Review search terms regularly and exclude queries that do not match the firm’s commercial intent.
Treat seasonality as a planning input, not a rule
Demand can shift around tax deadlines, year-end activity and business cycles, but a seasonal spike does not automatically justify more spend. Increase budget only when the campaign can absorb more traffic without sacrificing lead quality or conversion efficiency.
Optimise for new clients, not cheap leads
Track qualified enquiries, consultations and new clients by campaign and service. A more expensive lead may be preferable if it becomes a higher-value recurring client.

Common Google Ads budgeting mistakes for accountants
- Using one campaign for every service
- Relying on broad match without search-term control
- Optimising for form volume instead of client quality
- Failing to track calls
- Using automated bidding before conversion data is reliable
- Increasing spend before fixing weak landing pages or slow follow-up
How much should an accounting firm start with?
Start with the smallest budget capable of generating enough clicks and conversions to produce useful data in the chosen service and location. If the available budget is too thin across several campaigns, narrow the scope rather than spreading it across everything.
