Sources: official agency, pricing and product pages, fetched October 4, 2026. US prices in USD. “Not listed” means we did not find it on the pages we fetched.

How did we pick these agency SEO tools?

We looked for tools that make multi-client SEO and GEO work practical: separate client workspaces, client-ready reporting, and enough tracking capacity to cover a roster. We ranked them on how much client work they automate, reporting options and price at agency scale. Every fact is from vendor pages fetched on October 4, 2026.

Our rules:

1. Multi-client by design. Each pick has workspaces, client seats or agency plans.
2. Official pages only. Prices and features come from each vendor’s own site.
3. Ranking is editorial. We did not run client accounts through every tool.
4. Agency prices when published. Where an agency price is not published, we point to the vendor’s page instead of guessing.

What are the best SEO tools for agencies in 2026?

1. Mentionova: best for agencies adding AI search to SEO retainers

Why it’s #1: Mentionova’s agency reporting covers your entire client roster from one login: one workspace per client, white-label reports under your logo, and role-based access so each client sees only their own results. Its agents handle the recurring client work, such as competitor research, answer engine monitoring, content briefs and the weekly report, and nothing ships without approval.

• Best for: SEO and GEO agencies that want per-client AI visibility reporting and drafted fixes without adding headcount.
• Price: brand plans start at $99/mo billed annually ($125 monthly). Mentionova’s pricing page has a separate “For agencies” view; check it for current agency plan prices.
• SEO automation: scheduled workflows, such as a weekly content refresh from Search Console decay, draft the work and pause for an editor before anything is published.
• Trade-off: it is not a backlink or keyword database, so most agencies pair it with an SEO suite.

2. Semrush: best classic SEO suite for agency teams

Verdict: Pick Semrush if your agency needs one deep SEO dataset. The SEO plan is $117.33/mo billed annually ($139 monthly) for 5 websites and 500 tracked keywords; Advanced ($455.67/mo billed annually) covers 40 websites with API data integration.

• Agency extras: a Lead Generation add-on ($90/mo) gives you a branded profile on the Semrush Agency Partners platform; extra users start at $45/mo.
• Trade-off: per-user and per-website limits make large rosters expensive.

3. SE Ranking: best low-cost white-label SEO reporting

Verdict: Pick SE Ranking for white-label client reporting on a budget. The Agency Pack starts at $69 per month billed annually and is an add-on with white-label reporting, client seats and unlimited scheduled reports, on top of Core ($103.20/mo billed annually) or Growth ($223.20/mo billed annually).

• AI search: the AI Search add-on costs $89/mo ($71.20 billed annually) for 200 prompts.
• Trade-off: the full agency setup is several line items: plan, Agency Pack and AI add-on.

4. Peec AI: best AI search tracking for growing agencies

Verdict: Pick Peec AI if AI visibility is a core client service. Agency plans offer per-client tracking and white-label reporting: Essential $245/mo (10,000 credits), Growth $495/mo for boutique agencies with 3 to 10 clients, and Scale $795/mo for 11 to 25+ clients.

• Trade-off: Peec focuses on AI search; it does not replace an SEO suite.

5. Otterly.AI: best for unlimited client workspaces

Verdict: Pick Otterly.AI if you want many client workspaces at a low price. Standard is $189/month with unlimited workspaces, unlimited brand reports, a Looker Studio connector and API access, and Otterly runs an Agency Partner Program.

• Trade-off: Standard includes 100 search prompts in total; each extra 100 prompts costs $99.

• Trade-off: ongoing client tracking costs from $150 per project per month.
