10 Best Advertising Agencies Worldwide

Choosing among the best advertising agencies means matching confirmed services and markets to your brief. This global shortlist helps you compare capabilities and choose whom to contact.

1. Ogilvy

Best for: Businesses seeking advertising alongside related brand, content, public relations, or experience services. Ogilvy lists capabilities across these disciplines, making it a broad fit for briefs that extend beyond advertising. Its listed location is global, but confirm the offices and markets relevant to your needs. Ask which services would be handled together and which teams would support each market. Confirm the current scope and team availability before comparing proposals. Pricing is not public; request a quote.

2. McCann

Best for: Businesses looking for an agency that identifies advertising as a service and publishes a worldwide office network. McCann has a direct fit for advertising briefs, and its listed offices provide a starting point for discussing work across markets. The available service information does not detail a wider offering, so confirm any other disciplines your campaign requires. Ask which teams cover your target markets and what work they can take on. Verify current availability and scope, then request a quote.

3. Grey

Best for: Businesses focused on advertising that want to explore an agency with locations in multiple countries. Grey identifies itself as an advertising agency and lists its locations, supporting its fit for internationally oriented briefs. Its documented services focus on advertising, so confirm directly if you also need content, media, or other related services. Ask about the markets relevant to your plans, the team responsible, and its proposed scope. Check current availability and request a quote.

4. 72andSunny

Best for: Brands considering a global creative agency and willing to confirm whether its services fit an advertising brief. 72andSunny describes itself as a creative agency serving brands and lists offices in several countries. Its available information confirms creative agency services but does not specifically identify advertising as a service. Ask which services it can provide for your brief and which markets its teams can support. Confirm scope and team availability before deciding whether to request a quote.

5. Havas Creative

Best for: Businesses exploring creative work connected with media and brand experiences across markets. Havas Creative describes a global agency network combining creativity, media, data, and technology for brand experiences. This offering may suit a brief spanning several of these areas, though the information does not describe it simply as an advertising service. Ask which network agency and team would suit your needs, and confirm market coverage, current scope, and availability. Pricing is not public; request a quote for the defined work.

6. Havas

Best for: Businesses considering advertising as part of a wider communications or marketing brief with international scope. Havas states that it offers advertising, communications, and marketing services to local and global clients, with operations across continents. This combination may suit needs that extend beyond advertising. Ask which team or service area would lead your work and whether it covers your intended markets. Confirm current capabilities and availability for your brief. Pricing is not public; request a quote.

7. BBDO

Best for: Businesses exploring an agency office network that are prepared to verify advertising capabilities directly. BBDO provides an official office-search page, establishing a network of agency offices. The available information does not confirm specific advertising services, so the office network alone does not establish fit for your brief. Ask which agency or office handles the work you need, what services it offers, and whether it covers your markets. Verify current team availability and scope before requesting a quote.

8. WPP

Best for: Businesses seeking a route into a global marketing-services organization and willing to identify the right agency for advertising work. WPP describes a global network of companies and provides a contact route for its services. The available information establishes WPP as a marketing-services organization, not as a distinct advertising agency. Ogilvy is identified as one company in its network, but your brief may call for a different provider. Ask which agency fits your services and markets, then confirm its current scope and availability. Request a quote from the relevant provider.

9. Havas People

Best for: Businesses exploring brand and business support across regions, provided they first establish whether advertising is included. Havas People describes a global network supporting brands and businesses, with locations listed in North America, the UK, India, and Australia. This supports its geographic reach, but does not confirm advertising as a service. Ask what services it offers for your brief and which regional team would handle the work. Confirm current availability and scope; request a quote if appropriate.

10. Publicis Groupe

Best for: Businesses investigating a group-level connection to advertising agencies and ready to identify the provider they need. Publicis Groupe has an official document referring to advertising agencies within the group. The available information does not identify a distinct agency for your brief or establish its services and market coverage. Ask which agency is relevant, whether it provides the advertising work you need, and which locations its team can support. Confirm current capabilities, scope, and availability before comparing proposals. Pricing is not public; request a quote from the relevant agency.

How to choose an advertising agency

• Define the brief. Specify whether you need advertising alone or related work in brand, content, communications, media, or experiences.
• Match confirmed services. Check that the agency explicitly offers the work you need. Ask directly about capabilities that are not clearly described.
• Check market coverage. Confirm the relevant office or team for each market instead of relying only on a global network description.
• Verify availability and scope. Ask which people or teams would handle your brief, what they would deliver, and whether they are available.
• Compare proposals consistently. Give agencies the same brief and compare services, responsibilities, market coverage, and pricing. If pricing is not public, request a quote.

FAQ

What should I look for when choosing a global advertising agency?

Start with confirmed advertising services and the markets you need to reach. If your brief includes other disciplines, check whether the agency documents those capabilities and can support them with an available team.

Do all agencies here explicitly confirm advertising services?

No. Some identify advertising directly, while others document creative, marketing, brand support, or an agency network without confirming advertising as a specific service. Verify the current scope with the relevant agency.

How can I find out what an agency will charge?

Request a quote based on your brief, required services, and target markets. Ask for the proposed scope and responsibilities alongside pricing so you can compare offers consistently.
