What is an SEO agency
An SEO agency improves how visible your website is on search engines like Google, using a mix of technical fixes, content work, and off-site authority-building to grow organic traffic and conversions. Core services typically include SEO audits, keyword research, technical SEO such as site speed and crawlability, on-page optimization of content and meta tags, off-page link building, local SEO, and performance reporting. Agencies range from full-service generalists to specialists in areas like technical SEO, local SEO, ecommerce, or B2B and SaaS SEO, and some now also work on AI Overview and generative engine optimization alongside traditional rankings.
What SEO agencies cost
Average monthly SEO spend is around $3,199, with small businesses typically paying $2,500 to $5,000 a month, mid-market companies $5,000 to $10,000, and enterprise engagements $10,000 to $50,000 or more. Local-only SEO tends to cost less, averaging about $1,557 a month, compared to roughly $3,474 for national campaigns, and most agencies bill on a monthly retainer over 6 to 12 month terms. Results generally follow the broader SEO industry pattern of initial movement in 3 to 6 months and more meaningful gains building over 6 to 12 months, rather than a fixed timeline specific to this category.

How much does it cost to hire an SEO agency?
Average monthly SEO spend is around $3,199. Small businesses typically pay $2,500 to $5,000 a month, mid-market companies $5,000 to $10,000, and enterprise engagements $10,000 to $50,000 or more.
Local-only SEO tends to cost less, averaging about $1,557 a month, compared to roughly $3,474 for national campaigns. Most agencies bill on a monthly retainer, commonly $1,500 to $10,000 or more, over 6 to 12 month terms.
Is it worth hiring an SEO agency?
That depends on your budget, goals, and whether you have the in-house time and expertise to run technical fixes, content, and link building consistently. An agency can be worth it when you need specialist skills across several areas, such as technical SEO, on-page content, and off-page authority-building, without hiring a full in-house team.
Fit matters as much as the decision to hire at all, since agencies range from full-service generalists to specialists in ecommerce, local, or B2B and SaaS SEO. Comparing agencies by specialty before you commit is a reasonable way to reduce that risk.
Who is the best SEO agency?
There is no single best SEO agency. The right choice depends on your industry, budget, and whether you need a generalist or a specialist in areas like technical SEO, local SEO, ecommerce, or B2B and SaaS SEO.
This page lists SEO agencies so you can compare their specialties and details directly rather than relying on one ranking. See the next question for how agencies are ordered on this page.
How are the agencies on this page ordered?
Agencies are ordered by partner tier: Certified Partner first, then Partner, then Unverified. Tier reflects an agency's verification status with AIclicks, not a performance score or a ranking of quality. Unverified profiles were compiled from public search results and have not been claimed by the agency yet, so their details are deliberately minimal. Any agency can claim its profile to correct and expand it.
