The either/or question is the wrong question
Small budgets force choices, so 'should we do SEO or PPC?' feels like a sensible question. But the two channels compete on the same page of results under different rules, and each produces data that makes the other cheaper. PPC is rented visibility: instant, precise and gone the moment you stop paying. SEO is owned visibility: slow to build, then compounding. Run together, PPC buys you the months SEO needs, and SEO steadily reduces the amount of traffic you have to rent.
This article covers the four combined tactics that matter most for a UK small business, plus a way to think about splitting the budget that does not rely on a magic percentage.
Cover the gap while rankings build
A new website, or a new service page on an established one, usually takes months to reach page one for competitive terms, especially local ones where rivals hold review and link advantages. Rather than treating that period as dead time, run ads on precisely the keywords your SEO plan targets. You gain revenue immediately, and you learn which keywords actually convert before investing months of content effort in them.
The discipline is the taper. Review rankings monthly at keyword level. When a page holds a stable top-three position for a term, cut bids on that exact term and watch total combined clicks for a few weeks. If organic absorbs the demand, bank the saving and redeploy it to terms still climbing. Keep paying for terms stuck on page two, where organic earns almost nothing.

Share search-term data in both directions
This is the cheapest win of running both channels, and almost nobody does it systematically.
From PPC to SEO
- The search-terms report shows the real queries that led to conversions, not just clicks. Those exact phrases belong in your title tags, H2s and page copy.
- Question-style queries that triggered your ads make ready-made FAQ entries and blog topics.
- Responsive search ads are a laboratory for title tags: when one headline consistently wins the click-through battle, adapt it for the matching page's title.
From SEO to PPC
- Search Console terms with high impressions but an average position of eight or worse are proven demand you cannot yet reach organically: bid on them.
- Queries you rank well for but with poor click-through suggest weak messaging; borrow your best-performing ad copy for the meta description.
- Organic query data sharpens negative keyword lists, filtering out job-seekers, DIY queries and irrelevant locations before they waste spend.
Double-listing your money SERPs
When you hold both an ad and a strong organic listing for the same query, the two together generally collect more total clicks than either would alone, and you push one more competitor below the fold. You also get two messages on one page: the ad can carry a time-limited offer while the organic listing carries authority and reviews.
Paying for clicks you might have received free only makes sense selectively. Double-list where the economics justify it:
- Your highest-converting commercial keywords, where one extra enquiry pays for a week of clicks.
- Your brand name, whenever a competitor bids on it.
- Seasonal peaks, when demand and competition spike together.
- Launches, where the organic page is too new to rank but the offer cannot wait.
Splitting the budget without a magic number
Any fixed formula is a fiction, because the right split depends on where your rankings already are. A more honest approach is scenario-based:
- New site, few rankings: weight the majority of spend to PPC for immediate revenue, while the SEO budget goes into technical foundations and the handful of pages targeting your most valuable terms.
- Established site with solid rankings: reverse the weighting; PPC becomes a precision tool for gaps, brand defence and seasonal pushes.
- Seasonal business: keep SEO investment steady year-round, since content compounds, and concentrate PPC into the weeks when buyers actually buy.
Rebalance quarterly using one number: blended cost per lead across both channels. If shifting £200 a month from ads to content lowers the blended figure over two quarters, keep shifting. If it raises it, you have found the current ceiling for SEO's share and should hold there.
Key Takeaway
Run PPC on the exact keywords your SEO plan targets, then taper spend keyword by keyword as pages reach stable top-three positions. Feed converting search terms from ads into titles and page copy, and bid on high-impression queries Search Console shows you cannot yet reach organically. Judge everything on one blended cost per lead, reviewed quarterly, and double-list only your highest-value commercial and brand SERPs, where an extra click genuinely pays.
Measure it as one system
Separate channel reports hide the interactions you are paying for. Segment both channels into brand and non-brand: brand PPC should be judged on defence and pennies-per-click, not celebrated for conversions it merely intercepted from organic. In GA4, be aware that last-click views flatter paid search; look at conversion paths to see how often organic research precedes a paid click, and vice versa.
Two practical habits complete the picture. First, blend Search Console and Google Ads data in a free Looker Studio report so the same keyword's paid and organic performance sit on one row. Second, run an occasional brand-pause test to keep an honest estimate of how much paid traffic is genuinely incremental. Get those right and the budget conversation becomes arithmetic rather than argument.
