Ottawa's SEO scene ranges from Glebe storefronts to firms with three-decade histories and offices across the country. This list was put together by reading public review platforms including Clutch, Google Reviews, Trustpilot, DesignRush, and each agency's own site, and pulling together the ones with a real, verifiable presence serving Ottawa businesses right now.
1. Azuro Digital
Area: Downtown Ottawa (150 Elgin St) with clients across Canada · Rating: 4.9 on Google (66+ reviews)
Azuro Digital is a web design, development, and SEO/AEO shop based on Elgin Street with additional offices in Toronto and Calgary. Reviewers consistently point to fast turnaround on edits and improvements in search rankings and traffic after projects launch. It suits businesses that want SEO bundled with a full website rebuild rather than as a standalone service.
2. seoplus+
Area: Ottawa (head office) with a Toronto office and US clients · Rating: 4.9 on Clutch (52 reviews) · Since: 2012
Headquartered on Exhibition Way, seoplus+ has built its reputation on SEO and PPC work for mid-sized and enterprise clients.

It's a fit for businesses that want an agency-sized team without a boutique's informality.
3. WSI eStrategies

WSI eStrategies is the Ottawa franchise of the WSI digital marketing network, offering SEO, PPC, and web design. Reviews highlight professionalism and a genuine lift in sales tied to their campaigns, with an A+ Better Business Bureau rating backing up the client feedback. Good for smaller local businesses that want a long-established process rather than a boutique's custom approach.
4. Mediaforce Digital Marketing Agency
Area: Ottawa, with additional teams in Toronto and London, ON · Since: 1996
Mediaforce is one of Canada's older full-service digital marketing shops, founded by Joe Bongiorno and now running SEO, PPC, social, and web design out of three Ontario cities including Ottawa. Client reviews on Clutch cite strong cost-to-value scores and, in at least one case, triple-digit percentage traffic growth in the first year of a campaign. Suits businesses that want SEO folded into a broader, multi-channel marketing retainer.
5. EDKENT Media
Area: Ottawa branch of a Toronto-headquartered agency · Rating: 4.9 on Google · Since: 2014
EDKENT Media runs an Ottawa-specific SEO practice as part of a larger Canadian agency network. A client review describes moving from page four or five of Google results into the top three of page one after working with the team, and reviewers describe the agency as fast, focused, and available. A reasonable pick for a business that wants a national agency's resources applied to a local ranking problem.
6. MARSWorks Inc.
Area: St. Laurent Blvd, Ottawa · Rating: 4.8 for quality on Clutch · Since: 1997
MARSWorks has been operating in Ottawa since 1997, combining SEO and PPC with web and app development. Clutch reviewers give the firm high marks for responsiveness and technical range across platforms, with a 5.0 willingness-to-refer score. It leans toward larger projects, with typical engagements in the tens of thousands of dollars, so it suits established businesses more than very small ones.
7. Notionhive
Area: Ottawa, with a second office in Dhaka, Bangladesh · Rating: 4.8 on Clutch (14 reviews) · Since: 2019
Notionhive pairs SEO with brand strategy, design, and broader marketing technology work, and has grown to serve several hundred client brands.

A fit for businesses that want SEO handled alongside a rebrand or design refresh.
8. Marwick Marketing
Area: Ottawa, serving clients across Canada · Since: 2012
Marwick Marketing is a Google Partner agency built around search marketing, SEO, and paid search. Reviews across Clutch, Google, and the Better Business Bureau describe the team as responsive and organized, with specific praise for boosting organic traffic through technical fixes and content optimization. Suits businesses that want a Canadian-owned agency with a straightforward focus on search rather than a wide menu of unrelated services.
9. Digitly
Area: Ottawa and multiple other cities · Rating: 4.5 TrustScore on Trustpilot (8 reviews) · Since: 2022
Digitly is a newer, smaller digital marketing agency offering SEO, PPC, and social media management, with an Ottawa presence among several other markets it serves. Clients cite strong communication and technical proficiency, and improvements in click-through rate and bounce rate on their sites. As one of the newest firms on this list, it has a shorter track record than the others, so ask for recent case studies before committing.
10. PeakSpire
Area: Ottawa, service-business focused · Rating: 5.0 on Google · Since: 2021
PeakSpire is a founder-led shop that pairs local SEO with WordPress web design specifically for Ottawa service businesses, such as trades and professional services aiming for the Google Map Pack. Reviews describe clients landing on page one after a rebuild and ongoing local SEO work. It's a fit for a single-location service business rather than a company chasing national search volume.
How We Built This List
This list was compiled entirely from public sources, including Clutch, Google Reviews, Trustpilot, DesignRush, and each business's own website. Ottown did not test, hire, or independently verify the work of any agency named here. It is not a paid placement and no business on this list paid for inclusion or ranking. Ratings and review counts reflect what was visible at the time of research and can change. This list was last reviewed in August 2026.
