Should One Agency Do SEO and PPC?

Bundling SEO and PPC under one agency is pitched constantly as an efficiency win, “one team, one strategy, unified data.” Whether that pitch holds up depends less on the bundling itself and more on whether the agency actually has deep expertise in both, or is treating one as an afterthought to win the other.

The genuine case for one agency handling both

SEO and PPC share real, valuable overlap: PPC campaigns generate exact-match search volume and conversion data that can sharpen SEO keyword prioritization, and understanding which terms you’re already paying to rank for helps avoid wasting organic effort on keywords you’ve already got covered through ads. In practice, that looks like pulling the Google Ads search terms report against your Search Console query data every month: any term converting well on paid that’s absent from your organic queries is a real content gap, not a guess. It also means both channels can report against the same conversion rate and revenue numbers in GA4, instead of two teams presenting different attribution models for the same sale. When one team has visibility into both, these insights flow naturally instead of getting lost between two separate vendors who never talk to each other.

The genuine case for keeping them separate

SEO and PPC are different disciplines with different skill sets, timelines, and success metrics. PPC rewards fast iteration and immediate, measurable results. SEO rewards patience and long-term authority building. An agency built primarily around one often treats the other as a secondary offering, competent enough to sell as a bundle, but not where their actual best talent and attention sits.

The real question: which one is the agency actually built around?

Ask directly which discipline the agency was originally founded around, and how long they’ve offered the other. An agency with 10 years of deep SEO expertise that added PPC as a service line 18 months ago is telling you something different than one built with genuinely equal depth in both from the start. Neither answer is automatically disqualifying, but it should shape your expectations for which side gets senior attention.

Check who specifically works on each channel

Ask whether the same person handles both your SEO and PPC, or whether they’re genuinely different specialists who happen to work at the same agency and coordinate on your account. A single generalist handling both is a meaningfully different offering than two dedicated specialists sharing data and strategy, even though both get marketed as “we handle SEO and PPC.”

Look at case studies or examples from each discipline independently

Rather than accepting a combined pitch, ask to see SEO results and PPC results as separate examples, applying the same skepticism covered in how to read between the lines of case studies. If one side’s examples are noticeably thinner, less specific, or less impressive than the other, that’s a fairly reliable signal of where the agency’s actual depth sits, regardless of how the bundled pitch is framed.

A quick example of how this plays out

Picture a mid-size e-commerce brand spending $8,000/month on Google Ads and $4,000/month on SEO through the same agency. Six months in, PPC conversion rate has climbed steadily thanks to weekly bid and creative testing, but the organic blog hasn’t published a new article in two months and rankings for the brand’s core category terms haven’t moved. That’s not automatically a red flag on its own, but paired with an account manager who can speak fluently about Quality Score and ad group structure but goes vague on backlink profile or content gaps, it’s a fairly clear signal of where the agency’s real bench strength sits. The fix isn’t necessarily firing them, it’s asking directly for the SEO lead’s name, their recent work samples, and a monthly content cadence in writing.

A reasonable way to decide

• Choose one agency for both if: you’ve confirmed genuinely dedicated specialists on each side, with real, comparable examples of strong results in both disciplines.
• Consider separating them if: one side of the agency’s work clearly outshines the other, or the same person is expected to run both without dedicated depth in either.
• Either way: insist on data sharing between the two functions even if run separately, the same coordination discipline covered in splitting responsibilities cleanly, since the coordination benefit is real even without a single vendor holding both contracts.

The efficiency argument for bundling is real, but it only pays off if both sides are genuinely strong. A single mediocre vendor handling two channels isn’t more efficient than two excellent specialists who simply share their data, it’s just fewer invoices.

Frequently asked questions

Is it cheaper to bundle SEO and PPC with one agency?

Sometimes. Agencies often discount a bundled retainer by 10-15% compared to hiring two separate vendors. That discount is only a genuine saving if both sides of the bundle are actually strong, paying less for two mediocre services isn’t a deal.

How do I tell if an agency’s SEO team is just an afterthought to their PPC business?

Ask how long they’ve offered SEO as a service, how many dedicated SEO specialists (not account managers) they employ, and for two or three SEO-only case studies with specific ranking or traffic numbers. Vague answers or a single generalist covering both channels are the clearest signs.

Can I switch from a bundled agency to separate specialists later?

Yes, and it’s a common move once a business scales enough to justify the coordination overhead. The transition works best when you keep the same reporting cadence and insist the outgoing agency hands over full account access and keyword or campaign history to whoever takes over, the same handoff discipline described in how to fire your SEO agency without tanking your rankings.
