Compare the scope, named specialist, deliverables, implementation support, reporting and commercial goals. A provider should explain what is included, who performs the work and how progress connects to qualified leads or operational value.
Ask three things before you sign: which parts are included, which stay your responsibility, and how priorities change when the data reveals a better opportunity than the one in the proposal. A provider who cannot answer the third question is selling a package, not a plan.
Clear ownership, visible evidence and consistent measurement are what separate a working engagement from a monthly report. Ask who performs the work, where you can see it, and against which period the result will be judged.
Companies targeting more than one language or country should also review the multilingual SEO approach. It separates translation from localized search intent, technical language signals and market-level measurement.
