The 30-second answer
- You need leads in the next 30 days? Google Ads.
- You want a lead machine that compounds? SEO.
- You have $2K+/month and want both? Run Ads while SEO matures, then taper Ads as organic takes over. This is what works for most small businesses.
Now the math.
Three numbers you need first
You can't choose intelligently without these:
1. Average lifetime customer value (LTV) 2. Closing rate from lead → customer 3. Cost per click in your industry/market (Google Keyword Planner gives a fast estimate)
A roofer with $12,000 LTV, a 30% close rate, and $25/click economics looks completely different from a yoga studio with $600 LTV, 50% close rate, and $4/click.
Google Ads: the case for
- Speed. Live tomorrow, leads this week.
- Predictable. Spend $X, get roughly Y leads. Easy to scale.
- Testable. You learn which keywords, headlines, and offers convert in days, not months.
- Geo-targeted. Show only to people in your service area.
Google Ads: the case against
- Stop paying = stop leads. It's rent, not equity.
- Costs rise every year. Many industries have seen CPCs double in 4 years.
- Conversion-rate sensitive. A bad landing page burns budget fast.
- Click fraud and bot traffic quietly eat 5–15% of every campaign.
SEO: the case for
- Compounds. Rankings earned today still pay 24 months later.
- Higher trust. Organic results outperform Ads on click-through rate by 3–5x.
- One-time work. A great service page can generate leads for years.
- Defensive moat. Hard to dislodge once you're top 3.
SEO: the case against
- Slow. 3–6 months minimum to see real movement.
- Front-loaded effort. Lots of work before any lead.
- Algorithm risk. Google updates can shift rankings overnight.
- Hard to predict. "Spend $X get Y leads" doesn't apply.
The honest framework
If your monthly marketing budget is under $1,000
- Do only one thing well.
- If you need leads now → all into Google Ads on a tight 5–10 keyword set with a focused landing page.
- If you can wait 6 months → all into SEO on Google Business Profile, citations, and 3 well-targeted service pages.
If your budget is $1,000–$3,000/month
- Best play: 60% Ads / 40% SEO.
- Ads keep the pipeline full while SEO ramps. After 6 months, slowly shift the ratio toward SEO.
If your budget is $3,000+/month
- 40% Ads / 40% SEO / 20% retargeting + content.
- This is where compound growth kicks in. By month 12, organic should be your largest single channel.
The mistake to avoid
The most common mistake we see: a business spends $2,000/month on Google Ads for 18 months, then realizes they have zero organic traffic and zero brand assets to show for $36,000 of spend.
Even if you choose Ads first, allocate at least $300–$500/month toward SEO foundations (Google Business Profile, reviews, basic content, technical fixes). That tiny line item is what gives you optionality 12 months from now.
A sanity check on any quote
Whether you're hiring an Ads manager or an SEO, ask:
- "What's the target cost per lead you're aiming for?"
- "What's the breakeven based on my LTV?"
- "When should I expect to see ROI?"
If they can't answer those three questions in plain numbers, find someone who can.
