The SEO industry is full of empty promises and vanishing agencies. Here is the exact due-diligence framework serious business owners use to find a genuine, results-driven growth partner.

"Better rankings" is not a business goal. "20 additional inbound leads per month at a cost-per-lead below $80" is a business goal. Questions to ask yourself: How many new customers/month would transform my business? What is my current cost-per-acquisition? What is my realistic budget and what ROI justifies it?
Demand verifiable case studies with specific data (industry, baseline, strategy, outcome, timeline). Ask to speak directly with 2-3 current clients. Any agency that balks at this request is one you should not hire.
Search "SEO Agency [their city]" — are they in the top 5? Run their site through Google PageSpeed. Check their GBP and their own backlink profile. If they can't rank themselves, they can't rank you.
Green flags: Month-to-month contracts, clear deliverables, transparent dashboards, you own all created assets.
Red flags: 12-month minimum contracts with early exit fees, vague monthly management fees, locked out of your own GBP.
Sample monthly report should answer: "Did this month's investment move my business forward?" Activity should be connected to outcomes — not just traffic graphs.
$1,500–$3,500/mo for single location. $3,500–$8,000+/mo for national or high-competition.
No. Start with 3-6 months to evaluate results.
Check Google Search Console for trending impressions and position improvements.
White-hat = Google-approved, sustainable. Black-hat = shortcuts that cause penalties.
