Technical SEO Tools

Introduction

Managing SEO for several clients can rapidly become disorganized—slow audits, inconsistent reports, and technologies not scalable. There we have been. Not only is it time-consuming, but organizing complicated technical data across several dozen sites can result in lost opportunities and confused client correspondence. That’s why we’ll guide you through these essential technical SEO tools for agencies—to streamline processes and boost efficiency. These tools aren’t just popular, they’re ones we’ve trusted to deliver measurable results time and again. When you’re juggling high-volume websites and client expectations, the right tools make all the difference.

What Makes a Technical SEO Tool “Agency-Grade”

Not all SEO tools are built for agencies. Agency-grade tools need to handle high-volume websites, integrate with other platforms, and, most importantly, provide actionable insights. When choosing tools, we focus on features that save time, improve communication, and help explain SEO value to clients—because a tool that can scale and provide real-time results is far more valuable than one filled with vanity metrics.

Core Technical SEO Tools We Use and Recommend

Screaming Frog: The Technical Audit Workhorse

Screaming Frog is our go-to tool for comprehensive website audits. It crawls websites to uncover broken links, duplicate content, redirect chains, and more. Its custom extractions and JavaScript rendering features make it a favorite for technical SEO at scale. We also use it in combination with the Google Search Console API to pull in click data, giving us a holistic view of how Google sees the site.

Why You Should Use It: Screaming Frog is a must-have if you want a quick and dependable approach to do extensive website audits. It’s ideal for companies managing several clients, scalable, reasonably priced.

Sitebulb: Visual SEO Intelligence

Where Screaming Frog provides raw data, Sitebulb provides visual insights. Its crawl maps and visualizations are perfect for explaining complex SEO issues to clients or internal teams. It’s ideal for onboarding new SEOs and showcasing issues like site architecture flaws.

Why You Should Use It: If your clients need clear, visual reports or you’re working with mid-tier audits, Sitebulb’s intuitive interface will save you time and make explaining technical issues a breeze.

SEMrush and Ahrefs: Competitive and Link Audits

When it comes to competitive research and backlink audits, SEMrush and Ahrefs are the gold standards. SEMrush excels in keyword audits and visibility tracking, while Ahrefs shines in backlink profiling and identifying toxic links.

Why You Should Use It: We trust both SEMrush and Ahrefs because they offer powerful backlink tools that help identify link-building opportunities and areas of improvement. Whether it’s for keyword research or identifying potential SEO risks, these tools deliver the insights you need.

Pro Tip: Use both tools together to cross-reference backlink data. You’ll often find discrepancies that can help uncover opportunities or problems you didn’t see before.

Google Search Console and Log Files

Google Search Console is essential for any SEO strategy. But we don’t just monitor performance reports. By cross-referencing GSC with crawl stats and server logs, we can identify how bots behave and address crawl budget waste.

Why You Should Use It: GSC is free, yet powerful—it’s essential for tracking performance, identifying indexing issues, and understanding how Google interacts with your site. Pair it with a log analyzer to maximize its potential.

PageSpeed Insights, Lighthouse CI, and Treo.sh

Core Web Vitals (CWV) matter. But passing CWV scores isn’t the endgame. Tools like Lighthouse CI and Treo help monitor real-user metrics over time, allowing you to pinpoint LCP, FID, and CLS issues with precision.

Why You Should Use It: If you’re serious about improving user experience and maintaining high rankings, these tools will give you ongoing insights into how your site’s performance is affecting real users.

Emerging and Overlooked SEO Tools for Agencies

JetOctopus: Fast, Visual, and API-Friendly

JetOctopus is an enterprise-level crawler designed to handle massive sites with ease. It offers beautiful visualizations and fast crawling speeds, outperforming other crawlers like Deepcrawl, often at a better price point.

Why You Should Use It: If you’re working with large clients or e-commerce websites, JetOctopus should be on your radar. Its speed and visual reporting are a game-changer when it comes to diagnosing issues quickly.

Oncrawl: For SEO-Data Correlation

Designed as a data-driven tool, oncrawl links behavioral insights with crawl data. We follow how word count influences ranking positions or how crawl frequency influences traffic.

Why You Should Use It: For data-heavy clients who need insights beyond traffic graphs, Oncrawl provides deep correlations that will help you show real SEO ROI.

Google Looker Studio + Sheets + Zapier

Automated dashboards are essential for keeping clients informed. By integrating Google Looker Studio with Sheets and Zapier, we can build real-time SEO health reports that alert us (and our clients) to changes in traffic, rankings, or crawl errors.

Why You Should Use It: Want to save time on manual reporting? These tools work together to give you real-time, actionable SEO insights that are client-ready. Setting them up once saves you countless hours every month.

Our Workflow: How We Sequence Tools for Maximum ROI

When we onboard a new client, here’s how we structure our workflow:

  • Week 1: Start with a Screaming Frog crawl + GSC + Ahrefs audit for a comprehensive initial assessment.
  • Week 2: Use Sitebulb for architecture mapping and visual insights.
  • Week 3: Dive into log file analysis and conduct Core Web Vitals testing using Lighthouse.
  • Ongoing: Use JetOctopus or Oncrawl for deeper insights and ongoing tracking.

We rotate tools based on the client’s size, industry, and budget, but we never rely on a single tool for all conclusions.

When to Ditch a Tool (And Why We Have)

A tool that no longer serves its purpose becomes dead weight. For example, we moved away from Moz Pro because of outdated backlink data and dropped RankMath’s crawler due to accuracy issues.

Why You Should Care: Don’t let outdated or inefficient tools slow your agency down. Regularly evaluate tools for accuracy, scalability, support quality, and integration with your workflow. If a tool adds more noise than value, it’s time to move on.

What Clients Really Need from These Tools

At the end of the day, clients want clear answers:

  • Why did traffic drop?
  • What’s the one fix we should prioritize?
  • How does this impact leads or revenue?

Tools only help if you can turn the data into actionable insights that solve their problems. That’s why we use these tools to deliver clear, prioritized recommendations that make sense to clients—not just SEO jargon.

Final Thoughts: Tools Multiply Expertise, Not Replace It

The right technical SEO tools are invaluable—but they’re only as good as the expertise behind them. Agencies need tools that scale, integrate, and provide clear, actionable insights. That’s why we’ve carefully curated our stack to not just analyze the web but to amplify our team’s expertise. Choose tools that support smart decision-making and make your team’s workflow faster, more efficient, and more valuable to your clients.

Our tools are teammates—they help us work faster, prove value, and create strategies that perform. But it’s our human insight that turns audits into actions and data into client ROI.

If you’re building or upgrading your agency’s SEO stack, start with the tools that have proven results for us—and help clients grow with confidence.
