What a well-built Google Ads account looks like in London
The first thing to check in any agency proposal is the campaign structure. A good agency splits your services into separate campaigns so each one gets its own budget, ads and landing page. A weak one puts everything in one campaign and lets Google decide. Here is the structure we would start with (example: roofing companies in London).
Roof replacements are among the highest-value home services, and homeowners usually get several quotes. Google Ads gets you into that shortlist, and tracking quotes to signed contracts shows which keywords actually pay.
Budget math: what you can afford to pay per lead
A good agency starts with your numbers, not a package price. The question is simple: how much gross profit does one job bring, and how many leads become customers? That gives you the most you can pay per lead and still make money. Below is a worked example for a residential roof replacement. Your own numbers will differ.
Use our cost per lead guide to work out your own target, and see what Google Ads costs in Canada.
Recommended from your numbers: $4,500 profit per job × 25% of leads that become customers = $1,125 breakeven. We start around half of that.
Worked example: a residential roof replacement
- Gross profit per job
- $4,500
- Leads that become customers
- 25%
- Breakeven cost per lead
- $1,125
- Starting Target CPA
- $563
Example numbers only. We calculate yours from your real job values and close rate before launch.
When to spend: the roofing marketing calendar
Demand for roofing is not flat through the year. The best agencies raise budgets before the busy season, not during it, and cut spend in slow months instead of wasting it.

Audit and tracking
Review past campaigns, set up and test call, form and booked-job tracking. Nothing else matters until this works.
- Weeks 2–3

Scale what works
Move budget to the campaigns with the lowest cost per booked job, and add Facebook and Instagram for offers and retargeting.
By day 90 you should know your cost per lead and cost per booked job for each service. If an agency cannot tell you those numbers, that is a warning sign.
Example account, illustrative figures. This is the view we report from: leads and cost per lead, not clicks.
How to score agency proposals side by side
Give each agency you speak to a score out of 5 on each line, multiply by the weight, and compare totals. It keeps the decision about results, not sales presentations.
| What to score | Weight | What a 5/5 looks like |
|---|---|---|
| Tracking plan | ×3 | Calls, forms and booked jobs tracked and imported into Google Ads |
| Understanding of roofing | ×3 | Talks about your job values, seasons and rules without being prompted |
| Account ownership | ×2 | Ad accounts in your name from day one |
| Contract terms | ×2 | Month-to-month or a short trial period |
| Reporting | ×2 | Monthly report on leads, cost per lead and booked jobs, with search terms shared |
| Who does the work | ×1 | You know the name of the specialist managing your account |
| Price transparency | ×1 | Management fee separate from ad spend |
What your monthly report should show
Every month you should receive numbers that connect ad spend to revenue. For roofing companies, these are the conversions and metrics that matter:
Ask to see these every month:
- Inspections booked
- Quotes sent
- Signed contracts and value
- Storm campaign leads
If your report only shows clicks, impressions and click-through rate, ask for more. See the conversion tracking checklist.
Example account structure: one prospecting campaign, one retargeting campaign, video only when it pays.
What marketing costs in London
London’s costs per click are lower than the GTA’s, which makes it one of Ontario’s most efficient large markets.
London budgets stretch further than Toronto’s. Most businesses can cover the city with focused campaigns per service, then add nearby towns.
Your total cost has two parts: ad spend, paid directly to Google or Meta, and the management fee you pay the agency. Keep them separate. For typical numbers, see how much Google Ads costs in Canada and try our cost per lead calculator.
What the best London agency should know about your market
London is Southwestern Ontario’s largest city, with Western University, major hospitals and a mix of older central neighbourhoods and new subdivisions in the north and south. Costs per click are lower than the GTA, which makes it a strong market for home services, legal and health businesses.
Searches that bring London customers
- “roofing london ontario”
- “furnace repair london”
- “personal injury lawyer london ontario”
- “dentist london ontario”
- “window replacement london”
A good agency will ask which of these services make you the most money, then build campaigns around those first. Nearby areas like St. Thomas, Strathroy, Komoka, Lambeth should be targeted only if you actually serve them.

How to choose the right marketing agency in London
Ask every agency these questions before you sign:
- Will the Google Ads and Meta ad accounts be in my name, and do I keep them if I leave?
- Is the contract month-to-month, and what is the notice period?
- Is my ad spend billed separately from your fee, so I can see what goes to Google and Meta?
- How will you track calls, forms and booked jobs, not just clicks?
- Who will actually manage my account day to day, and how many accounts do they handle?
- What will you report each month, and will you show me the search terms report?
- Can you show me work for a business like mine, with permission from that client?
- What happens in the first 30, 60 and 90 days?
Red flags to avoid
- They keep your ad account. If you leave, you lose years of data. Your accounts should always be in your name.
- Long lock-in contracts with high cancellation fees before they have shown any results.
- Guaranteed rankings or guaranteed lead numbers. Nobody controls Google’s or Meta’s auctions.
- Ad spend and management fee mixed together on one invoice, so you cannot see what Google was actually paid.
- Reports full of clicks and impressions but nothing about calls, leads or booked jobs.
- No questions about your business: margins, service area, capacity, which jobs you want more of.

Frequently asked questions
What is the best marketing agency in London?
For Google Ads, Local Services Ads and Facebook ads, our pick is PPC Pros Canada, and we wrote this guide. The best choice depends on your goal: a full-service agency may suit you better if you mainly need a brand and website.
How much does a marketing agency cost in London?
It depends on the scope. Paid ads management is usually a monthly fee, separate from the ad spend you pay Google or Meta. Full-service retainers that include websites, SEO and social media cost more.
Should I hire a local London agency or a Canada-wide agency?
What matters most is whether they understand your market, service area and province’s rules. Paid ads are managed online, so a Canadian agency that knows London well can serve you as effectively as one down the street.
Should I sign a long-term marketing contract?
Be careful. Month-to-month terms, or a short trial period, protect you if results do not come. Make sure you own your ad accounts either way.
What is the best marketing mix for London, Ontario?
Google Search as the base, Local Services Ads for trades, and Facebook for seasonal offers.
