How BestAdAgency ranks
Every listed company gets a score out of 100 from four criteria. The score sets the editorial order. Sponsored spots are sold separately, labeled, and never change a score.

Score calculator
Each criterion is scored 0 to 100. The total is the weighted average.
How a ranking gets made
- Sourcing. We build a long list from search results, marketplace partner directories, Clutch and Google listings, client referrals and free profile requests.
- Vetting. We check the website, team, location, founding date, public pricing, case studies and review profiles. Companies that can't be verified are not listed.
- Scoring. An editor scores each criterion from 0 to 100 using the evidence on file; the weighted total sets the order. Ties go to the company with more verified reviews.
- Publishing. Every list shows the date it was last updated. Lists are reviewed every quarter, and sooner when a company changes pricing or service.
- Corrections. Companies and readers can send corrections through the contact page. We reply within two business days.
Reviews
Ratings from Clutch, Google and Trustpilot link to their source, and the weighted average counts each source by its number of reviews. Reviews written on BestAdAgency are published only after the reviewer confirms a work email and an editor checks it. We show the most helpful critical review next to the most helpful positive one, and we never remove a genuine review because it is negative.
Sponsored spots
Up to three Sponsored spots sit above each ranking. They are labeled, priced in public, last 30 days, and anyone can take one by paying $1 more than the current holder. Payment never changes a company's score or editorial position. Full details are in the Sponsored spot rules.
Affiliate links and ownership
Some outbound links are affiliate links, marked with rel="sponsored". They never affect the order. BestAdAgency is owned by Exclusiva Inc, an ecommerce growth agency. Exclusiva may appear in agency rankings; when it does, it is marked and scored under the same methodology as every other agency. Exclusiva can't buy Sponsored spots on lists where it is ranked.
