The Best SEO Tools And Software For Agencies

Best Agency SEO Tools

Whether you are part of a huge digital agency, or just starting up your own SEO agency or freelance business – having the right SEO tools and software can make all the difference.

As the digital landscape constantly evolves, so too do the tools designed to help navigate it. But with such an abundance of SEO tools out there, how do you know which one your agency needs?

I’ve put together this detailed guide to help you find the right tool for your agency’s needs – split into free SEO tools, all-in-one tools that do a bit of everything, specialist technical SEO tools, keyword research tools and link building tools.

So, whether you're on the lookout for a robust all-in-one platform or niche software to refine a specific part of your strategy, I’ve got you covered.

Why SEO agencies need tools and specialist software

In the competitive world of digital marketing, standing out often depends on having an edge. For many SEO agencies, that edge is derived from the use of specialised tools and software.

Here's why:

Tools provide access to specialist data

At the heart of every effective SEO strategy lies data-driven decision-making. Agencies require accurate and up-to-date information to tailor their approaches for individual clients.

Specialist SEO tools offer access to granular data about keywords, backlinks, search trends and much more. This ensures that agencies aren't just working based on gut feelings but are making informed decisions backed by concrete data, leading to more effective and tailored strategies for their clients.

Tools can help with automation and streamlining processes

Specialist SEO software can automate a lot of the time-consuming and repetitive tasks that SEO agency workers have to do every day.

From tracking keyword rankings to generating reports, automation ensures that processes are streamlined. This not only bolsters productivity but also significantly reduces operating costs. When agencies can accomplish more in less time and with fewer resources, it directly contributes to enhanced profitability.

What agencies need to consider when choosing a tool

Before you commit to a new tool for your digital agency, there are a couple of things you need to consider first to make sure you get the right tool for your needs:

The initial cost of the tool – and the different pricing levels

Every agency operates within a budget, making cost a significant factor when choosing the right tools. While many tools seem affordable initially, it's essential to be wary of hidden costs. Some tools operate on a scaling pricing model, meaning the more you use them, the steeper the price becomes.

This can be particularly challenging for growing agencies that might see their tool expenses skyrocketing unexpectedly. Therefore it's crucial to read the fine print, understand the pricing structure and forecast potential future costs before committing.

Specialist or ‘all-in-one’ tools?

While all-in-one SEO tools can offer a range of features, there might be occasions when their functionalities in certain areas are not as in-depth or advanced as those of the more specialist tools.

For instance, an all-in-one tool might offer a basic site crawling feature, but it might not be as detailed or versatile as a dedicated crawler like Screaming Frog.

Agencies need to evaluate their unique needs. If you frequently require in-depth analysis in a specific area, investing in a specialist tool might be more cost-effective in the long run. On the other hand, if a general overview suffices for most tasks, an all-in-one tool might be the better choice.

Free SEO tools for agencies

Free tools are always the best place to start! Whether you’re an established SEO agency or just starting out as a freelancer, you’ll find there’s plenty of free tools to use that can help you develop SEO strategies, audit websites, carry out keyword research and lots more.

Here’s our rundown of the best free SEO tools for digital agencies:
