Technical SEO tools are plentiful.

However, tools are just part of the equation.

Tools are useless without an experienced technical SEO professional to guide the strategy and ensure successful results.

But, within the hands of an experienced professional, tools can do many wondrous things. From scaling a site’s SEO effortlessly to creating content, it’s possible to improve things with less effort (rather than more hard work).

Tools can increase efficiencies, including:

• Identifying issues on-site, like crawling and indexing.
• Diagnosing page speed issues.
• Identifying missing or duplicate text and other elements.
• Redirect issues.
• And many others.

Your SEO tools arsenal, and how you use them, can mean the difference between great success and failure.

And indeed, there is no shortage of technical SEO tools for agencies.

Here are a few of the best you should consider.

1. Screaming Frog

Screaming Frog is the crawler to have.

To create a substantial website audit, it is crucial to first perform a website crawl with this tool.

Depending on specific settings, it is possible to introduce false positives or errors into an audit that you otherwise would not know about.

Screaming Frog can help you identify the basics like:

• Missing page titles.
• Missing meta descriptions.
• Missing meta keywords.
• Large images.
• Errored response codes.
• Errors in URLs.
• Errors in canonicals.

Advanced things Screaming Frog can help you do include:

• Identifying issues with pagination.
• Diagnosing international SEO implementation issues.
• Taking a deep dive into a website’s architecture.

2. Google Search Console

The primary tool of any SEO pro should be the Google Search Console (GSC).

This critical tool has recently been overhauled to replace many old features while adding more data, features, and reports.

What makes this tool great for agencies? Setting up a reporting process.

For agencies that do SEO, good reporting is critical. If you have not already set up a reporting process, it is highly recommended that you do so.

This process can save you if you have an issue with website change-overs when GSC accounts can be wiped out. If your account is wiped out, it is possible to go back to all your GSC data, because you have been saving it for all these months.

Agency applications can also include utilizing the API for interfacing with other data usage as well.

3. Google Analytics

Where would we be without a solid analytics platform to analyze organic search performance?

While free, Google Analytics provides much in the way of information that can help you identify things like penalties, issues with traffic, and anything else that may come your way.

In much the same way as Google Search Console works, if you set up Google Analytics correctly, it’s ideal to have a monthly reporting process in place.

This process will help you save data for those situations where something unexpected happens to the client’s Google Analytics access.

At least, you won’t have a situation where you lose all data for your clients.

4. Web Developer Toolbar

The web developer toolbar extension for Google Chrome can be downloaded here.

It is an official port of the Firefox web developer extension.

One of the primary uses for this extension is identifying issues with code, specifically JavaScript implementations with menus and the user interface.

Turning off JavaScript and CSS makes it possible to identify where these issues are occurring in the browser.

Your auditing is not just limited to JavaScript and CSS issues.

You can also see alt text, find broken images, and view meta tag information and response headers.

5. WebPageTest

Page speed has been a hot topic in recent years, and auditing website page speed brings you many useful tools.

To that end, WebPageTest is one of those essential SEO tools for your agency.

Cool things that you can do with WebPageTest include:

• Waterfall speed tests.
• Competitor speed tests.
• Competitor speed videos.
• Identifying how long it takes a site to load fully.
• Time to first byte.
• Start render time.
• Document object model (DOM) elements.

This is useful for determining how a site’s technical elements interact to create the final result or display time.

6. Google PageSpeed Insights

Through a combination of speed metrics for both desktop and mobile, Google’s PageSpeed Insights is critical for agencies that want to get their website page speed ducks in a row.

It should not be used as the be-all, end-all of page metrics testing, but it is a good starting point.

Here’s why: PageSpeed Insights does not always use exact page speed. It uses approximations.

While you may get one result with Google PageSpeed, you may also get different results with other tools.

Remember that Google’s PageSpeed provides only part of the picture, and you need more complete data for an effective analysis. Use multiple tools for your analysis to get a full picture of your website’s performance.

7. Google Mobile-Friendly Testing Tool

Determining a website’s mobile technical aspects is also critical for any website audit.

When putting a website through its paces, Google’s Mobile-Friendly testing tool can give you insights into a website’s mobile implementation.

8. Google’s Rich Results Testing Tool

The Google Structured Data Testing Tool has been deprecated and replaced by the Google Rich Results Testing Tool.

This tool performs one function, and performs it well: it helps you test Schema structured data markup against the known data from Schema.org that Google supports.

This is a fantastic way to identify issues with your Schema coding before the code is implemented.

9. GTmetrix Page Speed Report

GTmetrix is a page speed report card that provides a different perspective on page speed.

By diving deep into page requests, CSS and JavaScript files that need to load, and other website elements, it is possible to clean up many elements that contribute to high page speed.

10. W3C Validator

Screenshot of W3C Validator, December 2022

You may not normally think of a code validator like W3C Validator as an SEO tool, but it is important just the same.

Be careful! If you don’t know what you are doing, it is easy to misinterpret the results and actually make things worse.

For example, say you are validating code from a site that was developed in XHTML, but the code was ported over to WordPress.

Copying and pasting the entire code into WordPress during development does not change its document type automatically. If during testing, you run across pages that have thousands of errors across the entire document, that is likely why.

A website that was developed in this fashion is more likely to need a complete overhaul with new code, especially if the former code does not exist.

11. Semrush

Semrush’s greatest claim to fame is accurate data for keyword research and other technical research.

But what makes Semrush so valuable is its competitor analysis data.

You may not normally think of Semrush as a technical analysis tool.

However, if you go deep enough into a competitor analysis, the rankings data and market analysis data can reveal surprising information.

You can use these insights to better tailor your SEO strategy and gain an edge over your competitors.

12. Ahrefs

Ahrefs is considered by many to be a tool that is a critical component of modern technical link analysis.

By identifying certain patterns in a website’s link profile, you can figure out what a site is doing for its linking strategy.

It is possible to identify anchor text issues that may be impacting a site using its word cloud feature.

Also, you can identify the types of links linking back to the site – whether it’s a blog network, a high-risk link profile with many forum and Web 2.0 links, or other major issues.

Other abilities include identifying when a site’s backlinks started going missing, its linking patterns, and much more.

13. Majestic

Majestic is a long-standing tool in the SEO industry with unique linking insights.

Like Ahrefs, you can identify things like linking patterns by downloading reports of the site’s full link profile.

It is also possible to find things like bad neighborhoods and other domains a website owner owns.

Using this bad neighborhood report, you can diagnose issues with a site’s linking arising out of issues with the site’s website associations.

Like most tools, Majestic has its own values for calculating technical link attributes like Trust Flow, Citation Flow, and other linking elements contributing to trust, relevance, and authority.

It is also possible through its own link graphs to identify any issues occurring with the link profile over time.

Majestic is an exceptional tool in your link diagnostic process.

14. Moz Bar

It is hard to think of something like the MozBar, which lends itself to a little bit of whimsicality, as a serious technical SEO tool. But, there are many metrics that you can gain from detailed analysis.

Things like Moz’s Domain Authority and Page Authority, Google Caching status, other code like social open graph coding, and neat things like the page Metas at-a-glance while in the web browser.

Without diving deep into a crawl, you can also see other advanced elements like rel=”canonical” tags, page load time, Schema Markup, and even the page’s HTTP status.

This is useful for an initial survey of the site before diving deeper into a proper audit, and it can be a good idea to include the findings from this data in an actual audit.

15. Barracuda Panguin

If you are investigating a site for a penalty, the Barracuda Panguin tool should be a part of your workflow.

It works by connecting to the Google Analytics account of the site you are investigating. The overlay is intertwined with the GA data, and it will overlay data of when a penalty occurred with your GA data.

Using this overlay, it is possible to easily identify situations where potential penalties occur.

Now, it is important to note that there isn’t an exact science to this, and that correlation isn’t always causation.

It’s important to investigate all avenues of where data is potentially showing something happening, in order to rule out any potential penalty.

Using tools like this can help you zero in on approximations in data events as they occur, which can help for investigative reasons.

16. Google Search Console XML Sitemap Report

The Google Search Console XML Sitemap Report is one of those technical SEO tools that should be an important part of any agency’s reporting workflow.

Diagnosing sitemap issues is a critical part of any SEO audit, and this technical insight can help you achieve the all-important 1:1 ratio of URLs added to the site and the sitemap being updated.

For those who don’t know, it is considered an SEO best practice to ensure the following:

• That a sitemap is supposed to contain all 200 OK URLs. No 4xx or 5xx URLs should be showing up in the sitemap.
• There should be a 1:1 ratio of exact URLs in the sitemap as there are on the site. In other words, the sitemap should not have any orphaned pages that are not showing up in the Screaming Frog crawl.
• Any parameter-laden URLs should be removed from the sitemap if they are not considered primary pages. Certain parameters will cause issues with XML sitemaps validating, so make sure that these parameters are not included in URLs.

17. BrightLocal

If you are operating a website for a local business, your SEO strategy should involve local SEO for a significant portion of its link acquisition efforts.

This is where BrightLocal comes in.

It is normally not thought of as a technical SEO tool, but its application can help you uncover technical issues with the site’s local SEO profile.

For example, you can audit the site’s local SEO citations with this tool. Then, you can move forward with identifying and submitting your site to the appropriate citations.

It works kind of like Yext, in that it has a pre-populated list of potential citations.

One of BrightLocal’s essential tools is that it lets you audit, clean, and build citations to the most common citation sites (and others that are less common).

BrightLocal also includes in-depth auditing of your Google Business Profile presence, including in-depth local SEO audits.

If your agency is heavy into local SEO, this is one of those tools that is a no-brainer, from a workflow perspective.

18. Whitespark

Whitespark is more in-depth when compared to BrightLocal.

Its local citation finder allows you to dive deeper into your site’s local SEO by finding where your site is across the competitor space.

To that end, it also lets you identify all of your competitor’s local SEO citations.

In addition, part of its auditing capabilities allows it to track rankings through detailed reporting focused on distinct Google local positions such as the local pack and local finder, as well as detailed organic rankings reports from both Google and Bing.

19. Botify

Botify is one of the most complete technical SEO tools available.

Its claim to fame includes the ability to reconcile search intent and technical SEO with its in-depth keywords analysis tool. You can tie things like crawl budget and technical SEO elements that map to searcher intent.

Not only that, but it’s also possible to identify all the technical SEO factors that are contributing to ranking through Botify’s detailed technical analysis.

In its detailed reporting, you can also use the tool to detect changes in how people are searching, regardless of the industry that you are focused on.

The powerful part of Botify includes its in-depth reports that are capable of tying data to information that you can really act on.

20. Excel

Screenshot by author, December 2022

Many SEO pros aren’t aware that Excel can be considered a technical SEO tool.

Surprising, right?

Well, there are a number of Excel super tricks that one can use to perform technical SEO audits. Tasks that would otherwise take a significantly long time manually can be accomplished much faster.

Let’s look at a few of these “super tricks.”

Super Trick #1: VLOOKUP

With VLOOKUP, it is possible to pull data from multiple sheets based on data that you want to populate in the primary sheet.

This function allows you to do things like perform a link analysis using data gathered from different tools.

If you gathered linking data from GSC’s “who links to you the most” report, other data from Ahrefs, and other data from Moz, you know that it is impossible to reconcile all the information together.

What if you wanted to determine which internal links are valuable in accordance with a site’s inbound linking strategy?

Using this VLOOKUP video, you can combine data from GSC’s report with data from Ahrefs’ report to get the entire picture of what’s happening here.

Super Trick #2: Easy XML Sitemaps

Coding XML Sitemaps manually is a pain, isn’t it?

Not anymore.

Using a process of coding that is implemented quickly, it is possible to code a sitemap in Excel in a matter of minutes – if you work smart.

See the video I created showing this process.

Super Trick #3: Conditional Formatting

Using conditional formatting, it is possible to reconcile long lists of information in Excel.

This is useful in many SEO situations where lists of information are compared daily.

Although Tools Create Efficiencies, They Do Not Replace Manual Work

For any SEO agency that wants a competitive edge, SEO tools run the gamut from crawling to auditing, data gathering, analysis, and much more.

You don’t want to leave your results up to chance.

The right tools can provide another dimension to your analysis that standard analysis might otherwise not provide.

They can also give you an edge in creating an output that will delight your clients and keep them coming back for years to come.

Which of these tools will you use to wow your customers?
