Feature Comparison

LinkMyAgency

Wave goodbye to lengthy, confusing setup calls. LinkMyAgency generates a unique, professionally branded link for your agency.

This seamless process eliminates all technical hurdles for the client, making you look like a tech wizard and saving hours of support time per client onboarded.

Enterprise-Grade Security with OAuth

Stop the reckless practice of sharing passwords and login credentials forever. LinkMyAgency uses secure OAuth protocols to connect to platforms like Google Ads and Meta Business Suite.

Scaling a Growing Digital Marketing Agency

For agencies adding multiple new clients each month, the traditional onboarding process is a major bottleneck.
