The best Google Ads agency can do more than set up your Google Ads campaigns. It can set them up to reach your target audience using remarketing and landing page optimization strategies to increase leads and conversions.
They’ll also have the expertise to run campaigns throughout Google’s entire ad network: Google Search Ads (formerly Google Adwords), Display Ads, and Shopping Ads, as well as its “spin-offs,” Discovery Ads, Local Services Ads, App Download Ads, and the AI-driven Performance Max Ads.
Finally, a good Google Ads marketing agency should be able to run end-to-end campaigns and maximize your ROI within your set budget and timeframe.
These are all my considerations for choosing the best Google Ads agencies for this guide. I rounded up and ranked the seven best agencies and the best use cases of each.

How I compared the best Google Ads agencies
I did a lot of research and drew from my experiences as a digital marketer to put together the list above. I wanted to include a wide range of agencies: Those experienced with small, growing, and enterprise businesses, as well as agencies that specialized in certain areas of Google Ads, like remarketing or conversion rate optimization.
For a fairer assessment, I scored them against a rubric with their pricing, quantity of services, quality of services, customer support, and my own expert score.
Service comprehensiveness: 30%
This scores the completeness of each agency’s Google Ads services, including whether they service the entire Google Ads network (Google Search, Shopping, Display, Local Services, Discovery, App Downloads, and Performance Max Ads), and if they offer services for retargeting, conversion rate optimization, and ad copywriting and design.
Quality of services: 30%
Aside from how many services they offer, I also scored the quality of their services, like whether they analyze competitors, run A/B tests, add negative keywords, do conversion tracking, and adjust your campaign’s keywords to improve its effectiveness even after it’s live.
Pricing: 15%
I gave higher scores to agencies with transparent pricing plans, month-to-month contracts, full-service campaign management, and customized plans for clients.
Customer support: 15%
Good client support is essential to any good agency experience. I gave higher scores to agencies with 24/7 customer support, more support avenues, and transparent reporting measures, like real-time ad campaign monitoring dashboards.
Expert score: 10%
Here, I took into account my own experience as a digital marketer. My expert score includes the overall quality of each agency’s services, value for money, reviews from former clients, and whether or not they’re a Google Partner.
5 considerations when choosing the best Google PPC advertising agency for your business
Ultimately, the best Google Ads services agency will be different for every business. A growing tech startup will have different needs from a multi-franchise business. But there are a few common things that should be top considerations when choosing the best agency for your business.
Consider the services you need most, the agency’s area of expertise, and the level of partnership you need, aside from your general budget and timeline. Then answer the following questions.
- What Google Ads services do I need most? This is always the foremost consideration when choosing an ad agency, because different agencies have different areas of specialization. This also depends on your business’s main objectives with Google Ads, whether it’s to increase conversion rates, leads, or something more comprehensive.
- What kind of partnership do I need? Most agencies offer full-service partnerships and custom ad campaigns for your specific needs, while some offer independent services on a pay-as-you-go basis. Clarify which type of partnership your business needs to help with your decision.
- What niche or vertical specializations do I need, if any? All the agencies on this list cover a wide range of industries, but some have more expertise in certain areas. For instance, WebFX is experienced in B2B marketing, and KlientBoost in ecommerce and SaaS.
- How do I want to track campaign results? Every agency should be able to provide regular reports on your campaign’s progress and how well it’s meeting targets and KPIs. However, if you want more consistent and hands-on tracking, agencies like Straight North and WebFX have client dashboards that let you track your campaign in real time.
- What data guidelines and accessibility compliance measures do I need in place? Data and accessibility are growing concerns in online advertising, especially with Google. While most agencies don’t explicitly discuss these on their website, it’s worth asking, during your initial call, how they track audience data and if they take accessibility measures like adding audio captions to videos and using descriptive ad copy.
Frequently asked questions (FAQs)
