Most businesses treat PPC and SEO like two different departments with two different goals. One team runs Google Ads, while another handles search engine optimization on a completely separate track. Somewhere in between, the same keywords get targeted twice. That overlap leads to landing pages competing against each other, and ad spend going toward traffic that organic search already covers.

We've seen this play out with dozens of clients at Oikos Project, and the fix is almost always the same. Stop treating paid and organic as separate efforts and start running them as one search strategy.

This guide walks you through how to find keyword overlap and build a keyword strategy that covers both channels. From there, you'll learn how to allocate your budget based on the full customer journey, and why pairing organic SEO with paid ads builds lasting brand authority.

SEO vs PPC: Why Treating Them Separately Costs You

The debate around SEO vs PPC usually frames them as an either-or choice. But they both target the same search results on the same search engines, which means your PPC ads and organic results often compete for the same clicks.

Unlike SEO, which builds visibility over time, PPC delivers immediate visibility through paid search. That speed helps drive traffic fast, but without shared data between channels, it creates a problem.

And that cost shows up in specific ways. When your SEO and PPC strategies run separately, you end up bidding on keywords your site already ranks for (which is basically paying for traffic you were already earning).

Once both channels feed off the same performance data, that budget goes toward new keywords and gaps in your search results instead of duplicated effort.

Start with Keyword Research to Find the Overlap

Finding where your paid and organic keywords overlap is the fastest way to cut wasted ad spend. When we've run these audits, the gap between what teams think they're spending wisely and what the data shows is almost always bigger than expected.

Here's how to run the comparison yourself.

• Pull Data from Both Channels: Open Google Search Console alongside your Google Ads keyword report. Compare which search terms drive organic clicks to your site and which ones your PPC campaigns bid on. Seeing them side by side makes the duplication hard to miss.
• Spot Where SEO Efforts Already Cover Paid Keywords: Check your PPC data for any keyword where your site already ranks on page one. If you're paying for clicks on those terms, that budget could shift toward new keywords with no organic visibility. Pairing this with analytics tools helps you spot trends in search volume, so you catch seasonal shifts before they drain spend.
• Assign Each Keyword a Clear Role: Some search terms convert better through PPC ads, while others drive more value as organic content. These SEO insights help your SEO and PPC campaigns stop doubling up and start targeting the keywords each channel handles best.

The goal of this step is to walk away with a clear picture of where your paid and organic efforts duplicate each other and where the real opportunities sit.

From there, the focus shifts to organizing those keywords into a strategy.

Build a Keyword Strategy That Covers Google Search and Google Ads

A solid keyword strategy starts by sorting every keyword based on its search intent and where your site currently ranks. Here's how that breaks down by intent type.

As the above table shows, commercial and transactional search terms perform better through Google Ads with targeted ad copy and dedicated landing pages. These users are closer to buying, so PPC strategies that match the user's search intent convert at a higher rate.

Informational keywords bring a different kind of value. These relevant searches pull visitors to your website early in their research phase, and a strong content strategy turns those visits into lasting traffic through organic Google Search results.

Once you lay it out like this, the gaps stand out quickly. Your PPC data shows which Google search results your PPC teams are paying for that SEO could handle.

Combining SEO with Paid Campaigns and Why Both SEO Signals Help

Your paid and organic landing pages share more ranking signals than most marketers realize. Combining SEO fundamentals with your PPC campaigns means both channels reinforce each other.

And it all starts at the page level.

• Page Speed and Relevance Affect Both Channels: Search engines evaluate every web page for load time, relevance, and seamless user experience. A slow landing page hurts your ability to rank higher organically and drags down your Quality Scores in Google Ads. Fixing that page improves both SEO and PPC performance on your site.
• Organic Pages Can Handle PPC Work Too: We've seen organic pages outperform brand-new PPC landing pages more than once, mostly because the trust signals were already baked in. A web page with high-quality content and a strong click-through rate already has what search engines reward. Small ad copy adjustments turn that same page into a paid landing page without starting from scratch.
• Aligned Signals Lower Your Cost Per Click: When both SEO signals align with your paid campaigns, PPC quality scores improve and cost per click drops. Google rewards quality content and fast load times, which directly lower costs. This also lifts your click through rate and conversion rates across the website over time.

One set of strong pages serving both channels saves time, keeps messaging consistent, and means every keyword on your site works harder.

Now, let's look at where all of this plays out: the customer journey.

Map the Customer Journey to Your Search Strategy

Most conversions take multiple touchpoints, and each one calls for a different balance of paid and organic. A deeper understanding of that flow helps you place the right channel at the right moment.

Early on, people search for answers, not the products themselves. They type broad keywords into Google, and organic content like blog posts and guides works best here. SEO drives traffic to your website at this stage without costing a cent per click.

As those visitors move into consideration, their relevant searches get more specific. PPC delivers targeted paid ads right when these users are comparing options. And pairing those PPC ads with comparison-style SEO content on your site creates a seamless user experience across search engine results pages.

By the bottom of the funnel, a paid ad through Google Ads with a strong call to action closes the deal (skipping the organic side here usually means higher CPCs and lower conversions). And that's exactly why a single-channel view of your SEO and PPC falls apart at this stage.

Once that's established, the question becomes how to fund it.

Budget Allocation and Why Last Click Attribution Misleads You

Budget allocation between SEO and PPC should reflect how both channels contribute to conversions. But most teams rely on a default attribution model that hides half the picture. Here's what that looks like in practice.

• Last Click Attribution Only Credits the Final Touchpoint: Most Google Ads setups use this model by default, giving full conversion credit to the last interaction before a sale (that one blog post three weeks ago? It gets zero credit). For PPC teams running campaigns alongside SEO, this means organic touchpoints disappear from the data entirely.

• The Real Cost Shows Up in Specific Scenarios: Say a customer finds your website through organic search results after typing in broad keywords. They read three posts over two weeks, then click a paid ad and convert. Under this model, the ad gets full credit even though SEO content guided that customer through every earlier stage of search. It sounds like a small thing, but it shifts entire budgets in the wrong direction.

• Multi-Touch Models Fix the Blind Spot: Instead of crediting one interaction, these models spread credit across every touchpoint, from the first search engine visit to the final click. Your PPC teams get a clearer view of how each channel affects conversion rates and click-through rates. With that deeper understanding, you allocate budget based on full traffic distribution across your digital marketing efforts, not a single last click.

When your SEO and PPC strategies share one attribution model, your PPC ads and organic search terms compete less and cover more ground.

Align Your Search Strategy with Your Business Goals

At its core, this comes down to one thing. A unified search strategy only works when every channel points toward the same business goals.

Start by auditing where your SEO and PPC efforts currently overlap or conflict on your website. Once you have that picture, set shared KPIs that reflect those goals, like total SERP visibility across Google and blended cost per acquisition on your site.

These benchmarks keep your PPC strategies and SEO strategy aligned so your budget goes toward keywords that fill gaps, not keywords both channels already cover.

That alignment is what turns a successful SEO strategy into a full digital marketing engine for business growth. If you're ready to connect your paid and organic campaigns under one roof, get in touch with our team.
