How do you access Google Keyword Planner API data?

You need a Google Ads account with active campaigns (or a test budget). API v23 provides Historical Metrics (volume, bids) and Forecast (projected clicks at different budgets). Free accounts show rounded ranges instead of exact figures.

What's the difference between Local Services Ads and regular Search?

LSA is pay-per-lead, not pay-per-click. You pay for calls or messages, not impressions. For home services, LSA CPL ($30–$50) is typically several times lower than Search CPA ($400–$600). But you need a Google Business Profile with reviews.

Should you run ads without a website?

Technically yes — you can even link to an Instagram profile. But without your own landing page there's no conversion tracking, no click-to-call, and no funnel control. Start with at least a single-page site: project gallery, pricing, CTA. LSA works without a website — it only needs your Google Business Profile.

How to Evaluate Google Ads Potential: An LA Case Study

Published: February 17, 2026 · 6 min

TL;DR: Evaluated Google Ads potential for a permanent LED lighting installer in LA. Google Search alone doesn't scale — tops out at 75–89 clicks/month on a $3K budget, ROAS 1-2.7x. Multichannel (Search + LSA + YouTube + Meta) delivers 5-24x. Here's the methodology with real Keyword Planner API data.

A client asked me: "Should I invest in Google Ads?" Simple question, but the right answer requires data, not guesswork. I ran Keyword Planner API forecasts at 11 bid levels, pulled industry benchmarks, and built actual CPC curves. Here's what I found.

The Business

A company installing permanent LED facade lighting for residential homes in Los Angeles. Smart systems controlled via app — for holidays, everyday ambiance, and security.

Average ticket: $3,000–$8,000 per project (HomeGuide, HomeAdvisor benchmarks)
Target: upper-middle class homeowners, homes $800K–$3M
Niche: permanent outdoor lighting, growing 9.8% annually
Current presence: Instagram with 1,000+ followers. No website

Key blocker: you can technically run Google Ads to an Instagram profile, but without your own landing page there's no conversion tracking, no click-to-call CTA, and no funnel control. And LSA requires a Google Business Profile regardless.

Methodology: Two Data Types

I explicitly separate data sources in every analysis — and you should too:

KP — actual Google Keyword Planner API data: search volume, bid estimates, click/impression forecasts
bench — industry benchmarks (LocaliQ, WordStream, Grand View Research): conversion rates, close rates, cost per lead

Why separate them? So the client knows where you have hard data versus informed estimates. KP shows demand and click costs. But conversion to lead and sale — that's where benchmarks come in.

Keyword Analysis

Data pulled for the LA metro area, grouped by priority:

Priority 1 — hot installation queries:

Query	Vol/month	Bid range	Competition
christmas light installation	320	$181–$577	HIGH
permanent outdoor lighting	210	$63–$189	HIGH
christmas lights installation near me	140	$206–$655	HIGH

Priority 2 — consideration (comparison shoppers):

Query	Vol/month	Bid range	Competition
christmas light installation cost	70	$136–$492	LOW
best permanent outdoor lights	50	$75–$200	HIGH
permanent christmas lights cost	10	$42–$145	HIGH

The "cost" query at LOW competition is the best opportunity here — 70 searches/month with less bidding pressure.

Priority 3 — branded Govee queries (dominant brand in the niche): 720 searches/month. But these are mostly DIY buyers. For a professional installation service, it's a conquest play with lower conversion.

Total volume: ~2,900 searches/month, surging to 6,000–8,000 in peak November. Impression ceiling in LA: ~1,430/month.

The CPC Curve: What Keyword Planner Hides

Keyword Planner hides the real cost per click. Top-of-page bid and actual CPC are two very different numbers:

Top-of-page bid — $110–$655. That's the price for position #1. NOT the average CPC
Actual avg CPC — always lower thanks to second-price auction mechanics

I ran Forecast at 11 bid levels ($1–$500). Results for November (peak season):

Bid	Clicks	Avg CPC	Spend
$10	11	$9	$99
$15	13	$14	$171
$50	89	$40	$3,567
$100	143	$78	$11,248
$200	176	$134	$23,533

Three takeaways:

There's a ceiling. You can't buy more than 1,430 impressions in LA at any bid
Growth is nonlinear. Doubling the bid from $50 to $100 gets +60% clicks but +215% spend
Sweet spot at $3K/month: bid $40–$50, avg CPC $35–$40, 75–89 clicks

In the off-season (June), traffic drops 5–10x. Impression ceiling: ~200/month. CPC also drops — $28 at a $50 bid.

Why Search Alone Won't Scale

Here's the Search-only funnel for peak November:

Budget: $3,000
Clicks: 75–89 (KP)
Leads (CVR 3–5%): 3–4 (bench)
Customers (close rate 30%): 1 (bench)
Revenue: $3,000–$8,000
ROAS: 1x–2.7x

One or two customers a month. You can't build a business on that. Now compare with multichannel:

Google Search: 1–2 leads
Google LSA (Local Services Ads): 10–20 leads at $30–$50 CPL
YouTube + Meta retargeting: 5–10 leads
Total: 16–32 leads/month → 5–9 customers → ROAS 5–24x

An order of magnitude difference. Same $3,000/month budget, but distributed across channels.

Media Split and Seasonal Strategy

Recommended split for $3,000/month:

Channel	Budget	Role
Google Search	$800	Hot demand, installation queries
Local Services Ads	$800	Best ROI for local services
YouTube	$600	Before/after videos, awareness
Meta (Instagram)	$500	Visual content + retargeting
Nextdoor/Yelp	$300	Local presence

During peak season (Oct–Dec) — shift 70% to Search + LSA. Off-season — shift to YouTube + Meta to build remarketing audiences for the next peak.

Phased Roadmap

Phase 1 (Mar–Apr) — foundation. Ad spend $500–$1,000/month. Build landing page, set up Google Business Profile, launch LSA. Goal: first data and 1–2 customers.

Phase 2 (May–Jul) — SEO + awareness. Ad spend $1,000–$1,500/month. SEO for low-competition queries, YouTube and Meta for audience building. Goal: top-3 rankings, remarketing pool of 1,000+.

Phase 3 (Aug–Sep) — ramp up. Ad spend $2,000–$3,000/month. All channels at full capacity, geo-targeting premium zip codes (Beverly Hills, Bel Air, Calabasas). Goal: 10–15 leads/month.

Phase 4 (Oct–Dec) — peak season. Ad spend $3,000–$5,000/month. Revenue $15,000–$72,000/month. ROAS 5–24x.

Annual ad spend: $17,000–$27,500. Payback: 1–2 customers cover a month's budget.

Key Takeaways

Don't trust top-of-page bids. Actual CPC is 2–3x lower. Run Forecast at multiple bid levels
Search has a ceiling. In a niche local market, you're looking at dozens of clicks, not thousands
Multichannel isn't a buzzword — it's a necessity. LSA delivers 5–10x more leads at the same budget
Seasonality is an advantage. 6 months before peak = time for SEO, reviews, and channel testing
At $3K+ average ticket, one customer pays for a month of ads. The barrier to entry is low
