Why ROI from Google Ads matters

Every budget line must deliver outcomes. ROI is about more than clicks—it ensures that traffic is relevant, visitors convert, and campaigns scale profitably.

Example: A Toronto plumbing company reduced wasted spend by 60% by switching from broad to high‑intent keywords and tightening geo‑targeting.

Step 1: Build the right foundation

• Structure by service or product. Keep tightly themed ad groups.
• Use high‑intent keywords. e.g., Google Ads management services, local PPC consultant, paid search agency.
• Target only where you serve. Set strict location inclusion and exclusions.

Step 2: Choose the right bidding strategy

• Manual CPC: Best for new accounts with limited data and a need for control.
• Automated bidding (Target CPA / Maximise Conversions): Shift once you have 30–50 conversions per month for reliable learning.

Step 3: Write ads that convert

• Use clear calls to action: Book a Free PPC Audit Today.
• Highlight differentiators: Family‑owned Canadian business, Award‑winning UK agency.
• Add extensions: call, location, and sitelinks for trust and visibility.

Step 4: Optimise landing pages

• Speed: Aim for under 3 seconds.
• Clarity: Strong, relevant headlines and focused copy.
• Forms: Keep to essentials (name, email, phone).
• Proof: Testimonials, reviews, and trust badges.

Step 5: Track conversions properly

Install Google Tag Manager and set up conversion actions for forms, calls, purchases, and store visits. Monitor Cost per Lead (CPL) and Return on Ad Spend (ROAS).

• Canada: phone calls often matter most.
• UK: in‑store visits are common for retail and furniture.
• USA: track both ecommerce sales and lead generation.

Step 6: Refine and scale

• Pause underperforming keywords and add negatives weekly.
• A/B test ad copy monthly.
• Only scale budgets once ROI is steady.

Step 7: When to hire a PPC agency

An experienced Google Ads agency helps reduce wasted spend, applies advanced tactics like remarketing and audience layering, and frees you to run the business.

FAQs

How much should a small business spend on Google Ads?

Start with 5–10% of monthly revenue. Increase budgets only after cost per lead and ROAS are stable.

How soon will I see results?

Initial improvements can appear within weeks. Expect 3–6 months for full optimisation due to testing, learning periods, and landing page changes.

Should I manage campaigns in‑house or hire an agency?

DIY is fine for early testing. Most SMEs gain consistency and better ROI by engaging a specialist PPC agency.
