Frequently Asked Questions
Not necessarily in the short term, but usually in the long term. PPC has a linear cost: if you want more traffic, you must pay more money. SEO has a front-loaded cost: you invest significantly in technical infrastructure and high-quality content early on.
Over time, as your organic visibility grows, your cost-per-visit in SEO tends to decrease significantly, whereas in PPC, it often increases due to competition. In high-trust industries, the 'cost' of SEO is often the cost of expertise, whereas the cost of PPC is the cost of the auction.
Measuring SEO ROI requires looking at a combination of Search Console data, branded search volume, and assisted conversions in GA4. While Google hides much of the keyword-level data for organic search, you can still measure the growth in 'Reviewable Visibility' by tracking how many of your target pages are appearing for relevant queries. You should also monitor your 'Share of Voice' in your specific niche.
By comparing your organic traffic growth against your total lead volume, you can establish a reliable correlation that serves as a quantifiable metric for ROI.
PPC is the better starting point for a new business because it provides immediate data. Without an existing reputation or backlink profile, SEO will take time to generate measurable results. By starting with PPC, you can buy the data you need to understand which messages resonate with your audience.
This 'purchased insight' can then be used to inform your SEO strategy, ensuring that when you do invest in content, it is targeted at keywords that are already proven to convert in your paid campaigns.
It is rarely advisable to stop PPC entirely, even with strong SEO. Maintaining a presence in both paid and organic results allows you to occupy more 'real estate' on the search engine results page. This dual presence increases the likelihood of a click and prevents competitors from bidding on your brand name.
A better approach is to optimize your spend: use SEO to capture the high-volume, educational traffic and use PPC to defend your brand terms and target high-competition, high-intent keywords where organic competition is too fierce.
