Google Ads or SEO: how to allocate your budget

Allocate your budget around the sales or qualified enquiries you want to generate, the time available and your resources. Google Ads can help you test an offer through paid advertising. SEO involves improving pages, content and technical implementation to develop organic search visibility. You can use both, but a fixed budget split will not suit every business.

Compare costs and timing

Spending

Google Ads Search — Media, management, creative and landing pages

SEO — Audit, development, content and monitoring

Starting

Google Ads Search — Delivery after approval and activation; commercial results need checking

SEO — Discovery, indexing and the effects of improvements to monitor over time

Control

Google Ads Search — Budget, targeting and exclusions to set; volume depends on demand and auctions

SEO — Pages and content to improve; the search engine determines rankings

You do not pay Google for each organic click. You still fund the work needed to create, maintain and improve your website. Include your team's or provider's costs and the pages needed for acquisition when comparing channels.

Avoid promising an SEO result after six months. Google states that some changes can take effect in hours, others after several months, and some will have no noticeable impact. Competition, website condition and demand make commercial forecasts less certain. Google SEO guide.

Choose your first investment

You need to test an offer or page

A Search campaign limited to relevant queries can help you observe enquiries for an offer. Before paying for visits, check the form, payment process, contact details and tracking. A page that prevents visitors from completing the intended action can consume your budget while telling you little about demand.

Define the offer, service area, language, spending limit and decision you will make after the test. Use Keyword Planner forecasts to establish assumptions, then compare them with observed results. An estimate of clicks does not predict your sales.

You have useful pages with limited visibility

Examine indexing and queries in Search Console. If a page supports an important offer, choose a specific improvement: help crawlers access it, answer a missing question, clarify its title or improve links leading to it. Monitor changes within a defined scope. Our SEO strategy guide explains this approach.

Your team has limited time

Include production and review time in the budget. Campaigns require monitoring of spending and enquiries. Content needs someone who knows the offer, verifies information and organises updates. Start with a scope your team can maintain rather than several channels without ongoing attention.

Calculate the cost of an enquiry and a customer

Fictional example, not a market benchmark. A business spends CHF 2,000 on media and CHF 500 on campaign management. It receives 25 enquiries, ten meet its qualification criteria, and two become customers.

Cost per enquiry: 2,500 / 25 = CHF 100.

Cost per qualified enquiry: 2,500 / 10 = CHF 250.

Observed acquisition cost per customer: 2,500 / 2 = CHF 1,250.

Profitability then depends on margin and the other costs included. If several channels contribute to the journey, these ratios do not prove that advertising generated every additional sale.

For SEO, count spending and outcomes over the same period. Do not compare one favourable month of traffic with one month's costs if you invested in the pages earlier. Also separate enquiries from branded searches from those of people discovering your business.

Measure before reallocating budget

Agree on a common definition: confirmed order, qualified enquiry or signed contract. Reconcile advertising and analytics data with your CRM or orders. Our marketing attribution guide explains models and differences between tools; our marketing KPI guide connects measures with decisions.

1. Define the test

Record how much you can spend, the outcome to monitor, the usual sales cycle and stopping conditions. A long sales cycle requires following enquiries after the campaign ends.

2. Keep a comparable scope

Avoid changing the offer, prices, page and targeting at the same time. Record promotions, stock shortages or events affecting the period. If you can establish a comparable control group, a test can help estimate additional outcomes; with limited data, draw a limited conclusion.

3. Revisit the decision

Increase, maintain or reduce the budget based on commercial outcomes and observed limitations. A high CTR or improved ranking does not establish a profit. A disappointing channel can also expose an offer, page or tracking problem.

Match languages and service areas

Choose languages in which you can sell and support customers. Connect each ad to a complete page in the same language and review enquiries by region. Google supports geographic targeting but states that its signals do not guarantee 100% accuracy. Review presence or interest settings according to your business. Google Ads location targeting.

Prepare for 2027: review your DSA campaigns

In its June 11, 2026 update, Google announces that automatic upgrades of Dynamic Search Ads (DSA) to AI Max will begin in February 2027. Campaigns using Automatically Created Assets (ACA) or campaign-level broad match follow a separate timetable, with upgrades announced to begin in September 2026. Official announcement and updated timetable.

If you use DSA, identify affected campaigns and settings to preserve: landing pages, exclusions, brands and tracking. Review account notifications and test changes within a controlled scope. This announcement does not justify changing every company's SEO/advertising budget split.

Prepare a budget you can explain

Gather priority offers, complete costs, confirmed outcomes and available time. Choose the first obstacle to address and set the next review date. To plan your paid advertising or search engine optimisation, we can help define the scope and measures to monitor.
