SEO or PPC: How to Plan a Marketing Test

Search optimisation and paid campaigns involve different work, costs, and responsibilities. A useful budget starts with a business objective and a plan for evaluating progress.

There is no single spending split that fits every business. Work through the following questions before deciding where to begin.

What are you trying to learn or achieve?

Define the audience, offer, and action you want to support. Are you introducing a new service, helping customers find an established location, or testing demand for a particular product?

Set a review period and a limit on the money and staff time you can commit. Include the work needed to answer enquiries or fulfil orders.

Is the destination ready?

Review the page people will reach. It needs accurate information, a clear next step, and a working enquiry or purchase process. Test the journey before using it as the destination for a campaign.

For local services, check the consistency of business details and the usefulness of service-area information. See our local SEO checklist for a starting review.

What work can you maintain?

Search-focused work may include technical fixes, improving existing pages, and answering relevant customer questions. Identify who will maintain that information and how you will review its usefulness.

A paid campaign needs its own owner for setup, targeting, spending limits, creative, destination pages, and ongoing review. If you use Google Ads, its custom experiments guidance explains an option for comparing proposed changes with existing campaigns. Include those responsibilities when comparing proposals or tools.

How will you assess the test?

Define a useful enquiry or sale and check how it will be recorded. Review lead quality and handling effort alongside the number of responses. Keep direct campaign costs separate from preparation and maintenance work.

If attribution is incomplete, say so in the review. Avoid treating an apparent change as proof that one channel caused it when the offer, season, or customer journey also changed.

Start with a bounded plan

Choose the work that addresses the most immediate uncertainty. For example, a business could first test whether visitors understand a new service page, or whether a campaign reaches the intended audience. These are possible test goals, not fixed budget recommendations.

Review the evidence at the agreed point, then decide whether to continue, revise the offer, improve the page, or move effort elsewhere.
