Start with ownership and visibility
A good Google Ads agency should make the account clearer, not more mysterious. Cambridge businesses should own their ad account, their landing pages, their conversion data, and their reporting. If an agency will not give you direct account access, that is a warning sign.
The goal is not to find someone who can make dashboards look impressive. The goal is to find a partner who can connect spend to qualified enquiries, booked calls, sales opportunities, and revenue.
Questions to ask before hiring
Who owns the Google Ads account if we stop working together?
How will phone calls, forms, booked appointments, and qualified leads be tracked?
Will campaigns send traffic to dedicated landing pages or the homepage?
How often will search terms, negative keywords, and budget allocation be reviewed?
Do reports explain decisions and next steps, or only show impressions and clicks?
How do you handle branded search, competitor terms, and low-quality leads?
What a strong agency should diagnose
Before making big promises, an agency should understand your margins, service areas, lead quality requirements, close rate, sales process, and website conversion path. For Cambridge businesses that serve both local consumers and regional B2B buyers, the targeting can change significantly depending on whether the campaign is built for emergency demand, scheduled services, ecommerce, manufacturing, or professional services.
Account access
You should retain ownership and visibility

Reports should separate good leads from noise

Campaigns need pages matched to buyer intent
Red Flags
No clear conversion tracking plan
No discussion of landing page quality
Reports focused only on clicks, impressions, and CTR
One campaign structure reused for every industry
No explanation of how budget changes will be decided
The best agency fit
The best fit is usually an agency that can manage the campaign and the conversion path together. Google Ads performance depends on the keyword, the ad, the landing page, the offer, the form, the phone call, and the follow-up process. If any one of those is weak, the account can look busy while the business still feels no growth.
