How we chose
We compared agency fit by budget, industry, and AI-search readiness, not just size or awards. We also weighed contract flexibility, since a no-lock-in agency like Thrive reduces risk for first-time buyers compared with long minimum terms. We favored agencies with named case studies, transparent deliverables, and reporting that covers AI citations as well as rankings. We noted where large-agency scope exceeds small-buyer needs and where specialist focus requires other partners. We did not hire any agency hands-on, and prices are custom, so check each agency current proposal before signing.
Buying guide: what to ask before you sign
Start with fit: a $480 per month productized package and a $30,000 per month enterprise engagement are different products solving different problems, so match the agency to your budget and industry. A small local business does not need an enterprise team, and an enterprise brand will outgrow a productized package fast. Ask for named case studies with traffic, ranking, and revenue outcomes, and request the source period and KPI definition for every metric. Vague case studies without dates, baselines, or named clients tell you little about what the agency will do for you. Ask how the agency measures AI search, since rankings alone miss AI Overviews and chatbot citations. Request a sample AI visibility report, so you can see whether citations are tracked or only promised. Ask about contracts, since Thrive offers no long-term lock-in while others require minimum terms. Read the exit clause before signing, since switching agencies mid-program can cost months of momentum. Ask who actually works on your account, since seniority and account load affect results more than agency size. Meet the strategist who will run your account, not just the salesperson who closes the deal for you each month from now on. Finally, avoid any agency that guarantees rankings, since no agency controls Google results. Walk away from guaranteed timelines too, since algorithm updates can shift results without warning at all times.
Frequently asked questions
Can an SEO agency guarantee number one rankings?
No, no agency controls Google results, and any guarantee of a number one spot is a red flag. Reputable agencies report on traffic, leads, revenue, and AI citations, not guaranteed positions.
How much do SEO agencies cost?
Costs range from around $480 per month for productized packages to $30,000 per month for enterprise engagements, with most mid-market programs between $1,000 and $10,000 per month. Confirm scope and deliverables before signing.
How long does SEO take to show results?
Most SEO programs need three to six months for measurable movement, with content-led programs taking longer. Agencies that promise instant rankings usually rely on tactics that risk penalties.
What should an SEO agency report on in 2026?
Rankings, traffic, leads, revenue, and AI citations across Google AI Overviews, ChatGPT, and Perplexity. An agency that reports only on keyword rankings measures half the picture.
Should I hire an SEO specialist or a full-service agency?
Hire a specialist like Victorious if SEO is your main need, and a full-service agency like Thrive or SmartSites if you want SEO alongside PPC, design, or content. Specialists need other partners for paid media or CRO.
