The short answer
Google Ads produces solar leads within days at $80 to $300 each and stops the moment you stop paying. SEO produces leads at effectively no cost per lead but takes three to nine months to arrive. Most solar companies should run ads to carry the pipeline while the organic and local work builds underneath it.
- 01Ads rent demand. SEO owns it. Both are legitimate; they behave differently.
- 02Ads are the right answer in month one. SEO is the right answer in year two.
- 03The local profile and reviews sit between them: fast and free.
- 04Running both is cheaper than running either alone, because each improves the other.
This gets argued as a choice by people who sell one of the two. In practice they operate on different timescales and different cost structures, and the useful question is not which one but in what order and in what proportion.
How do they actually differ?
| Google Ads | SEO and local | |
|---|---|---|
| First leads | Days | 4 to 12 weeks for local, 3 to 9 months for pages |
| Cost per lead | $80 to $300, ongoing | Effectively $0 once established |
| Stops when | You stop paying, immediately | Slowly, over months of neglect |
| Scales by | Spending more | Publishing more and earning more reviews |
| Ceiling | Your budget | Search volume in your area |
| Control | High. Change it this afternoon | Low. You are a guest of the algorithm |
| Compounds | No | Yes |
The last row is the whole argument for SEO and the reason it survives being slow. Ad costs only go up as competitors bid; organic positions and review counts get harder for competitors to take the longer you hold them.
The sequence that works
- 01
Month one: both, but weighted to ads
Ads on, because you need leads this month. At the same time, the Business Profile corrected and review requests automated, which costs nothing and starts the slow clock. See local SEO for solar contractors.
- 02
Months two to four: ads carry, organic builds
Ads at full budget. Service area pages and core service pages written. Reviews accumulating. Nothing visible happening on the organic side, which is normal and is where most companies quit.
- 03
Months four to nine: the crossover
Map pack positions improve, service area pages start ranking, organic enquiries appear in the CRM. Ad spend can start being judged against a rising organic baseline rather than as the only source.
- 04
Month twelve onward: choose deliberately
With organic carrying a meaningful share, ad spend becomes a decision about growth rate rather than a survival requirement. Most companies keep both, at a different ratio.
The thing sitting between them
The Google Business Profile and reviews get discussed as SEO, and on the timescale they behave much more like ads: profile corrections often show within four to twelve weeks, and they cost nothing per lead.
For a solar company with a limited budget, that is the highest-return work available, ahead of both. It is free, it is fast by SEO standards, and it makes paid traffic convert better at the same time. See how to rank in the Google map pack.
Why is running both cheaper than either?
- Reviews lower ad costs. More reviews means a higher conversion rate on the same clicks, which lowers cost per lead and improves quality score.
- Ads inform SEO. The search terms report is real keyword data from your actual market, better than any tool. See solar SEO keywords.
- Brand familiarity compounds. Somebody who has seen your ads is more likely to click your organic result, and vice versa.
- Ads cover seasonal gaps. Organic is steady; ads can be turned up when the diary is thin and down when it is full.
When does one genuinely beat the other?
Ads alone make sense if you need leads within weeks, are testing a new territory before committing, or have crews idle now. SEO alone makes sense if you have no budget at all, or if your market has so little search volume that the ad auction is thin and organic is easy to dominate.
For everybody else, the honest answer is a ratio that changes over a year, starting heavily paid and ending more balanced. For what to expect from the slow side, see how long does SEO take for solar companies.
Ads are rent. SEO is a mortgage. Most businesses need somewhere to live while they are paying it off.

Common questions
- Should a new solar company do ads or SEO first?
- Both, in the same week, weighted to ads. Ads produce the leads you need this month; the Business Profile and review work cost nothing and start the slow clock immediately, which is the part you cannot buy later.
- Is SEO cheaper than Google Ads for solar?
- Per lead, dramatically, once established. In the first six months it is more expensive, because you are paying for work that has not produced anything yet. The crossover is usually somewhere between month six and month twelve.
- Can I stop ads once SEO works?
- You can, and most companies reduce rather than stop. Ads remain useful for filling seasonal gaps, testing new territories and defending your brand name, which is usually the cheapest campaign in the account.
