IN SHORT
Choose the agency.Check the evidence.
A Google Ads company should explain how search intent, the landing page and conversion measurement fit together. Start with your own cost per enquiry, not a growth percentage borrowed from another account.

What should you ask before signing?
Ask for a baseline before changes, demonstrable conversion measurement and a monthly explanation of what changed, why and what it did. Ask about direct competitors too: this source states that TheSEO does not serve yours. These are selection questions, not claims about another named agency.
The page after the click belongs in the review.
Keywords and exclusions follow services, products or regions. Adverts need a matching landing page. Clarity heatmaps and recordings help locate friction; the review also covers speed, mobile use, forms and buttons.
Baseline, structure, test, adjust.
Agree the offer, margins and audience first. Build the measurement plan and campaign structure, then test against actual conversions. Weekly adjustments use search terms and cost per result; monthly reporting returns to your baseline.
Management by location. Ad spend separate.
The English source gives the following monthly fees and one-off setup amounts. Setup covers structure, research, advert copy and conversion measurement. The advertising budget is paid directly to Google.
