Smart SEO & PPC Budgeting in 2025 for Maximum ROI

“We spent £2,000 on ads and got absolutely nothing in return.”

That’s exactly what a client told us during their on-boarding call. They had invested thousands into Google Ads without the right setup, no custom landing pages, no conversion tracking, no clarity on which keywords mattered. Their website wasn’t optimised. Their ad copy didn’t align with search intent. And their SEO? Non-existent.

They weren’t alone. Most small and growing businesses either:

Go all in on paid ads and hope for instant results,
Or focus solely on SEO, expecting to rank overnight.

Both approaches fall short without a strategy that accounts for timing, goals, and where your business is right now.

This post will walk you through how to balance your budget across SEO and PPC, how each channel delivers results, and when it makes sense to lean into one more than the other.

If you’re trying to make sense of digital marketing budgets in 2025 and want realistic expectations with measurable outcomes, this one’s for you.

First: Understand the Core Difference Between SEO and PPC

Let’s get something straight:

Channel	Speed	Cost	Sustainability	Ideal for
PPC (Pay-Per-Click)	Fast	Higher upfront	Short bursts	New products, fast testing, immediate leads
SEO (Search Engine Optimisation)	Slower	Long-term investment	Compounds over time	Sustainable traffic, long-term trust, lower cost per lead

SEO and PPC aren’t competitors. They’re teammates.

If PPC is your sprinter, SEO is your marathon runner. One gives you immediate visibility. The other builds authority over time.

At Juggernaut Technologies, we help clients budget across both channels strategically because using one without the other often leads to wasted time, wasted money, or both.

The 3-Phase Budgeting Framework That Actually Works

Here’s the SEO/PPC budget plan we use across a wide range of clients—from local trades to fast-growth eCommerce brands.

Phase 1:

The Launch (Months 1–3)

Focus: Speed + Testing

Budget Split: 70% PPC / 30% SEO

In the early stages, your priority should be getting traffic, fast, and learning from it. That’s what PPC is for.

You wouldn’t build a house without testing the soil.

Don’t build a long-term SEO plan without testing your keywords first.

What to do during this phase:

Run Google Ads with tight keyword focus (your main services + local area).
Create or refine landing pages that are focused on one goal only (e.g., a quote form, phone call, or booking).
Start foundational SEO work: fix technical issues, optimise key pages, and set up local SEO.

Check out our SEO Packages if you’re unsure where to begin. Even our Standard Plan gets the groundwork laid right.

Why this works:

You’re learning fast. You’re building a data-driven foundation. And you’re not sitting around waiting 6 months for Google to rank you.

Phase 2:

The Growth Curve (Months 4–6)

Focus: Optimisation + Momentum

Budget Split: 50% PPC / 50% SEO

Now you’ve got initial data. You know:

What keywords bring in leads
What pages convert (or don’t)
How much each lead costs you

Time to optimise your PPC based on what’s working, and double down on SEO by targeting keywords that already show intent.

What to do during this phase:

Tweak PPC ads and reduce spend on underperformers.
Build SEO content targeting mid-funnel keywords (e.g., “best local web design agency Belfast” instead of just “web design”).
Improve internal linking structure and build backlinks.

Want content that ranks and converts? Let us build a Custom SEO Content Strategy aligned with your ad data. (This is where many agencies drop the ball.)

Why this works:

You’re no longer guessing. You’re building on actual customer behaviour. And SEO starts to pick up steam less reliance on ads.

Phase 3:

The Flip (Months 7+)

Focus: Sustainability + Efficiency

Budget Split: 70% SEO / 30% PPC

By now, your SEO efforts should be generating organic traffic consistently.

That means you can scale back your PPC budget, reserving it for high-converting keywords, brand protection, and remarketing.

What to do during this phase:

Keep your top 3–5 best-converting PPC campaigns running (e.g., “emergency electrician Glasgow”).
Let SEO content and backlinks keep doing the heavy lifting.
Focus on conversion rate optimisation (CRO) to make the most of all that traffic.

Need help managing SEO AND PPC together? Our SEO + Paid Ads Packages do exactly that, under one roof with clear reporting.

Why this works:

You’re now in control. Your cost per lead drops. Your traffic is diversified. And your business can scale without being tied to ad spend.

Real-World Results: From Frustration to Flow

Let’s go back to our original client the one who wasted £2,000 on PPC with nothing to show.

Here’s what changed when they followed our SEO/PPC framework:

Metric	Before	After 6 Months
Leads per month	3–5	20+
Cost per lead	£110	£35
Organic traffic	Minimal	4,000+ visits/month
PPC ROAS	Untracked	4.2x

The only difference? Strategy. Not budget.

How Much Should YOU Spend?

This depends on your goals, your location, and your competition—but here’s a general rule of thumb for small to mid-size UK businesses:

Monthly Marketing Budget	Suggested Split (SEO / PPC)
£750–£1,500	60% SEO / 40% PPC
£1,500–£3,000	50% SEO / 50% PPC
£3,000+	Custom split based on results
