11 Best SEO Tools for Agencies Managing Multiple Clients

I’ve worked with SEO agencies of all sizes, and I’ve been in the thick of almost every SEO situation. Some agencies choose a set of specialized tools, while others prefer solutions that bring their entire workflow together.

The truth is there isn’t one software that works perfectly for every agency. Still, a few come very close.

In this post I present 12 tools that I believe are among the very best for SEO agencies. Each one stands out for certain tasks, although every tool tends to cover a wide range of SEO needs.

Here is a simplified overview of the 12 tools that I will be mentioning in this article:

Depending on your agency’s size, client type, or workflow, you might find some tools more useful than others. My aim is to share some insights on these tools and point out which tasks they perform best.

We made this review as part of a bigger analysis of the best SEO tools.

Why the Right Tools Matter for SEO Agencies

SEO agencies often handle many tasks:

• Keyword research
• Competitor analysis
• On-page and technical audits
• Backlink analysis
• Content optimization
• Reporting to clients

Choosing the wrong set of tools can mean duplicating work, missing key data, or dealing with unnecessary complexity. With the proper tools, the agency workflow is smoother. Teams can work together more easily, tasks are completed quicker, and you can rely on the data.

Using one platform for many tasks makes sense—especially for larger teams—but keeping a few specialized tools available is also wise. I’ve seen agencies try to use a single tool for everything, and while it sometimes works, it can also lead to frustration.

1. SEO.AI

I work at SEO.AI, so it’s no surprise I’m mentioning it first. Even so, I truly believe it’s one of the best AI-driven SEO platforms out there. Ranked as the #1 platform for AI SEO, it’s built to write and optimize content so that it appeals to both customers and search engine algorithms. From product feeds and articles to blog posts and metadata, SEO.AI offers a full suite of AI-driven features that help agencies create and optimize content at scale.

• Tasks It’s Great At
  • AI-Powered Content Creation: The AI SEO Assistant helps create descriptions, articles, and product feeds that align with Google’s algorithms and resonate with customers.
  • Real-Time SEO Scoring: Provides data-driven insights to show exactly which areas of your content need improvement.
  • Product Feed Optimization: Generates enhanced product attributes that often yield 15–30% more clicks in Free Listings and Google Shopping.
  • Built-In AI Chat: Avoid constant alt-tabbing or copy/pasting; the integrated chat and in-line assistant speed up the writing and editing process.

Agencies can get started with a free trial and quickly see how SEO.AI combines advanced data insights with AI-driven writing. It’s a powerful option whether you’re optimizing a few landing pages or overhauling thousands of product listings.

2. SEMrush

I’ve used SEMrush many times. Right out of the box it offers a wide range of functions that cover most SEO activities. This platform can serve as a hub for agencies because of its broad set of features.

• Tasks It’s Great At
  • Keyword research: Provides detailed data on search volume, keyword difficulty, and trends.
  • Competitor analysis: Gives insights into competitor traffic, organic keyword overlaps, and backlink profiles.
  • Site audits: Automated audits highlight errors, warnings, and suggestions for best practices.
  • Rank tracking: Regular tracking of keyword movements across different search engines.

3. Ahrefs

I can’t talk about SEMrush without mentioning Ahrefs. Both are frequently compared, and both are among the best. Ahrefs is especially known for its strong backlink data, which gives it a clear edge.

• Tasks It’s Great At
  • Backlink analysis: One of the largest backlink databases in the industry.
  • Keyword research: Offers in-depth keyword data, including click metrics and traffic potential.
  • Content gap analysis: Compares your site’s content with competitors to highlight missed opportunities.
  • Rank tracking & site audits: Solid modules that help keep your site’s health in check.

4. Moz Pro

When I think of a long-standing SEO SaaS, Moz Pro comes to mind. It is reliable, simple to use, and has an approachable feel that many teams appreciate. Agencies looking for a straightforward solution often choose Moz.

• Tasks It’s Great At
  • Keyword research: Offers a clear interface with an easy-to-understand difficulty score.
  • Site audits: Detects issues with site performance, indexing, or on-page configurations.
  • Rank tracking: Monitors keyword rankings on a daily or weekly basis.
  • Link building campaigns: Its link explorer is useful even if it isn’t as large as Ahrefs.

5. Screaming Frog SEO Spider

Screaming Frog is different. It is not a full-scale platform, but it is one of the most important tools for technical SEO. For agencies handling large websites, this tool can crawl thousands (or even millions) of pages and quickly identify errors.

• Tasks It’s Great At
  • Technical audits: Crawls the entire site to find status code errors, broken links, missing metadata, and more.
  • Redirection tracing: Points out redirect chains and loops.
  • Site structure analysis: Helps you get a clear picture of the site’s hierarchy and internal linking.

6. Surfer SEO

There is a growing trend for content optimization tools that give data-driven suggestions. Surfer SEO is one that stands out. It brings together keyword and on-page signals, making content optimization more systematic.

• Tasks It’s Great At
  • Content optimization: Offers recommendations for word counts, keyword usage, and relevant topics based on top-ranking pages.
  • Content briefs: Quickly generates guidelines for freelance writers or in-house content teams.

7. Google Search Console

Free and straight from Google, this tool is essential for every SEO agency. Not using Google Search Console (GSC) is like ignoring direct input from the biggest search engine available.

• Tasks It’s Great At
  • Performance tracking: Shows which queries bring in impressions and clicks.
  • Index coverage: Reveals how Google crawls your site and pinpoints any coverage issues.
  • Manual actions: Displays any penalties or warnings from Google.
  • URL inspection: Checks if a URL is indexed, blocked, or has rendering issues.

8. Google Analytics

Google Analytics (GA) answers the question of how visitors act once they land on your site. Not using GA is not an option for any serious SEO agency. Although it seems like just an analytics tool, it is key for making strategic decisions.

• Tasks It’s Great At
  • Behavior flow: Shows how users move from one page to another.
  • Goal tracking & conversions: Measures form submissions, e-commerce transactions, and lead generation.
  • Audience insights: Provides details on demographics, interests, and device usage.
  • Real-time monitoring: Displays traffic changes as they happen—very useful during campaigns or launches.

9. Majestic

For a closer look at link intelligence, Majestic is hard to ignore. Many teams use Majestic because its focus is on trust and citation metrics.

• Tasks It’s Great At
  • Link profile analysis: Its “Historic” and “Fresh” indexes let you see old versus new links.
  • Trust Flow & Citation Flow: Provides clear visual metrics that help gauge link quality.
  • Topical Trust Flow: Helps you understand how relevant the links are to a specific niche.

10. SE Ranking

SE Ranking may not be as well-known to everyone, but it offers a solid set of features for agencies. It covers the main aspects of SEO in one suite.

• Tasks It’s Great At
  • Rank tracking: Accurately tracks keywords across multiple regions.
  • On-page audits: Gives a quick overview of how well each page is optimized.
  • Backlink checking: Provides an overview of your external link profile.
  • Competitor research: Lets you compare the organic and paid strategies of your competitors.

11. All in One SEO (WordPress Plugin)

For agencies that work with WordPress sites, a dependable SEO plugin is a must. All in One SEO is a classic option. It is simple, covers most on-page SEO tasks, and integrates well with WordPress.

• Tasks It’s Great At
  • On-site optimization: Helps manage meta titles, descriptions, and canonical tags.
  • Sitemap generation: Automatically updates the sitemap as new pages or posts are added.
  • Social media integration: Lets you control how your content appears when shared.

12. AnswerThePublic

I have used AnswerThePublic to come up with unique angles and subtopics for content. It isn’t a full SEO suite, but it is very useful for generating content ideas and finding long-tail keyword opportunities.

• Tasks It’s Great At
  • Content brainstorming: Offers real questions that people are asking about your topic.
