Running Google Ads without someone watching the account closely is a fast way to burn a budget on the wrong keywords. Ottawa has a real cluster of agencies that specialize in paid search, from small shops working out of Preston Street to national players with an Ottawa-specific team. This list was put together from Clutch rankings, agency websites and case studies, and Google review counts, all checked in August 2026.
1. seoplus+
Area: Ottawa (head office), with a Toronto team and US clients · Specialty: Google Premier Partner paid ads management · Rating: 4.9 on Clutch (53 reviews)
seoplus+ is headquartered on Exhibition Way in Ottawa and holds Google Premier Partner status through 2026, a certification tier reserved for agencies that hit Google's ad-spend and performance thresholds. Their Clutch review count, 53, is the highest of any Ottawa-based paid search shop found for this list, which suggests a large and fairly steady client roster rather than a handful of showcase accounts. They suit businesses that want an agency big enough to have dedicated specialists per channel, not just one generalist running the account.
2. Mediaforce Digital
Area: Ottawa, with additional offices in Toronto, Vancouver and New York · Specialty: Certified Google Ads management alongside SEO and web design · Rating: 4.9 on Clutch (30 reviews)
Mediaforce runs its Ottawa operation out of an Elgin Street office and describes over two decades in internet marketing, with self-reported awards including a Top SEO Agency in Canada mention. Because they bundle PPC with SEO and web design under one roof, they're a fit for businesses that would rather have one agency own the whole acquisition funnel instead of coordinating separate vendors for ads and organic search.
3. WSI eStrategies
Area: Ottawa (Canotek Road) · Specialty: Pay-per-click management as part of a broader online marketing practice · Rating: 4.8 on Clutch (3 reviews)
WSI eStrategies calls itself Ottawa's most experienced online marketing agency and points to roughly 30 years of operating history. The Clutch review count is thin at three, so the rating carries less statistical weight than seoplus+ or Thrive, but it's one of the few agencies on this list with a physical, long-standing Ottawa address rather than a satellite presence. Best suited to businesses that value continuity and a local office over the newest ad-tech stack.
4. Encipher
Area: Ottawa · Specialty: PPC across Google and Bing, plus Meta advertising for lead generation and e-commerce · Since: 2016
Encipher is an Ottawa-based shop founded in 2016 that leans hard into lead generation and e-commerce clients, claiming over 300,000 leads and $50 million in client revenue generated across its history. They position themselves as an extension of a client's in-house marketing team rather than an outsourced vendor, which tends to suit service businesses that want frequent, direct contact with whoever is actually managing the account.
5. Ottawa Marketing Guys
Area: Ottawa (Preston Street) · Specialty: Search and display ads for local brick-and-mortar businesses
Ottawa Marketing Guys works out of a Preston Street office and specifically caters to physical storefronts, going as far as capping how many businesses in the same niche and city they'll take on at once, a deliberate move to avoid competing against their own clients. They report average click-through rates well above the typical industry range, though that figure is self-published rather than third-party verified. A reasonable pick for a local retailer or service business wary of being lumped in with a dozen competitors at the same agency.
6. POP INC
Area: Ottawa and Gatineau (offices in both) · Specialty: Google Ads management with in-house creative production
POP INC operates on both sides of the river, with a Bank Street office in Ottawa and another in Chelsea, Quebec, and reports more than 13 years managing accounts for over 150 businesses. Having design and video production in-house is the standout here, useful for businesses that don't already have creative assets ready to plug into a Google Ads or YouTube campaign.
7. Zwebra
Area: Ottawa · Specialty: Google Ads management across Search, Shopping and Local Services Ads
Zwebra is a Google Partner agency running a dedicated Ottawa PPC page with tiered packages built around specific monthly ad-spend ranges, from small local budgets up to established $4,000-plus spenders. They cite Google-certified specialists and about a decade of experience. The tiered, spend-based packaging makes it easier for a business to know roughly what they're signing up for before a first call.
8. Thrive Agency
Area: Serves Ottawa (one of 25 cities the agency operates in) · Specialty: Google Ads and Bing Ads management, plus social and eCommerce PPC · Rating: 5.0 on Clutch (100+ reviews)
Thrive is a national agency rather than an Ottawa storefront, but it maintains an Ottawa-specific service page and was named a 2026 top Ottawa PPC agency by Clutch with a perfect 5.0 rating across more than 100 reviews, plus a UpCity 2026 National Excellence Award. The scale here, offices in 25 cities, means more bench strength across ad platforms, which can suit a business running Google Ads alongside Bing and Nextdoor campaigns at once.
9. ThinkProfits
Area: Serves Ottawa remotely (headquartered in Vancouver) · Specialty: Google Search, Shopping, Display and remarketing campaigns · Rating: 5.0 on Google (48 reviews) · Since: 1996
ThinkProfits isn't based in Ottawa, but it has an Ottawa-specific landing page and a Google rating of 5.0 across 48 reviews, along with a founding date stretching back to 1996 and a claim of managing campaigns for over 3,000 businesses across North America. Worth including for businesses comfortable with a fully remote agency relationship in exchange for a long operating history and transparent flat-rate-style pricing starting around $1,000 a month.
A tenth agency, Clickwave, came up repeatedly in Ottawa PPC roundups as a small, well-reviewed local shop, but its website could not be reached during research for this piece, so it was left off rather than guessed at.
