42 of the Best SEO Tools for Auditing & Monitoring Your Website in 2024

For many years, Google algorithm updates have left marketers, SEOs, and business owners confused and concerned. I wonder if search engines like Google wait for you to get all of your ducks in a row, only to unleash an update that can make your efforts obsolete.

Plus, some secrecy behind how Google determines websites and their order of appearance on the search engine results page (SERPs) for different queries doesn’t help.

The good news is that there are several free and paid search engine optimization (SEO) tools for monitoring and auditing your site, like HubSpot's SEO Marketing Software. Not only can these tools help you improve your ranking, they can help you reduce or eliminate the impacts of Google updates that may sweep through your industry.

Free SEO Tools

These tools are free to use, but you might find a paid option that has more features. We’ve shared some of the best features in each tool, as well as how you can get the most out of them for your SEO strategy.

1. HubSpot Website Grader

Image Source

The goal of marketing is to generate traffic and qualified leads via the company’s website. That’s why, as marketers, we need to understand what we can do to improve the SEO of websites we manage.

I like that with HubSpot’s Website Grader, you enter your website URL and receive a report with actionable SEO insights. Here’s the result of the HubSpot website from the grader:

If you check your website and your report is not looking good, you can sign up for the HubSpot Academy SEO course to learn how to improve your website’s SEO, user experience (UX), and more.

With the HubSpot Website Grader, you can:

• Website performance: Learn about your website’s performance in seconds, identify specific performance issues, and receive actionable feedback on how to fix them.
• On-demand support: Receive how-to education on improving your website.
• Improve specific website issues: Gain access to a five-lesson HubSpot Academy course on Website Optimization to understand how to improve challenges with your website.
• Optimize for mobile: Discover how to optimize your website for mobile.
• Boost web security: Learn how you can implement website security best practices.
• Enhance the user experience: Personalize your website’s UX to create a delightful experience for users.

2. Google Search Console

Image Source

Google Search Console has several tools available to help you appear in the SERPs for the search terms and phrases your target audience is looking for.

If you’re the owner of a business or an SEO on your marketing team, Search Console can help you conduct an initial SEO analysis from scratch or update your existing SEO strategy with fresh keywords. I like that Google Search Console monitors, debugs, and optimizes your website — and you don’t need to know how to code to benefit from this tool.

Here are some website elements Google Search Console will teach you about and help you optimize:

• Keywords: Learn about the keywords your web pages are currently ranking for.
• Crawl Errors: Identify any crawl errors that exist on your website.
• Mobile Responsiveness: Understand how mobile-friendly your website is and discover opportunities to improve the mobile experience for users.
• Google Index: See how many of your web pages are in Google’s Index (if they aren't in Google's index, you can use the tool's URL Inspection Tool to submit a page for indexing).
• Analytics and Metrics: The website-related metrics that matter most to you, like clicks, impressions, average click-through rate (CTR), and average position.

3. Google Analytics

Image Source

Although Google Analytics has a paid version, the free version of the product can help you manage your website’s SEO — this is especially true if you pair Google Analytics with Google Search Console (which I recommend). In doing so, all of your website’s SEO data will be centrally located and compiled, and you can use queries to identify areas for improvement with the keywords and phrases you want your website and web pages to rank for.

Other ways that you can use the free version of Google Analytics are:

• Filtering your referral traffic: Get rid of the traffic that has the potential of ruining SEO reports, such as fake traffic.
• Comparing organic versus non-organic website traffic: Understand where your visitors are coming from and optimize those channels to increase traffic.
• Determining engagement metrics: Use Site Content Reports to determine engagement metrics on each web page, engagement for the directories and pages on your website, page exit metrics, and acquisition, behavior, and conversion of landing pages.
• Reviewing the Multi-Channel Report’s Assisted Conversions feature: Identify which of your channels led to the most conversions and the value they bring to your business.

4. SEO PowerSuite

SEO PowerSuite is a one-stop software for all your SEO needs, and is also one of the most budget-friendly options. I like this toolkit because it allows you to check as many websites as you need without limitations. It works with 550+ search engines and can track geo-specific positions, even down to the exact street address. The suite is highly customizable, with easy automation and white-label reporting.

Here is what you can do with four tools of SEO PowerSuite: 

• Rank tracker — Keep a close eye on how your website is ranking across various search engines. It's super handy for monitoring keywords and fine-tuning your strategy.
• Website Auditor — Get a list of issues and tips on how to fix them. Analyze any page of your website and see how well it is optimized for your target keyword. See what needs to be improved in your content to increase the optimization rate, and make all those changes right in the app.
• SEO Spyglass — Unveil your competitors’ backlink strategies and get insights to boost your site's authority. Make sure to check out the Backlinks history module to see the newly found and lost links of any domain and page.
• Link Assistant — Build a network of high-quality links, use their backlink manager, and make outreach and campaign management efficient.

5. The Free SEO Report Card by Singularity Digital

In exchange for your email address and a few data points, the SEO Report Card will cover:

Image Source

Traditional SEO tools are great for conducting research and audits when your business is already established. But what if you’re starting a new business venture and want to know what popular industries, topics, and ideas people are exploring? Google Trends is a great place to explore the untapped potential that can yield a large keyword landscape for your website.

Note that Google Trends isn’t where you’ll get granular data. I think this tool performs best when you use it as a compass to set a direction for your SEO strategy and then pair those insights with a more robust software like HubSpot’s SEO Marketing Tool.

Here's what you should look for in Google Trends:

• Trends: Look for trends in specific countries or regions of the world.
• Popular topics: Find popular people and long-tail keywords related to them.
• Comparisons: Compare and contrast trends over time.

10. Seolyzer

13. Seobility

Check My Links is a Google Chrome extension that ensures your links on both internal and external web pages work. For instance, if you were to search for a term on Wikipedia, Check My Links could tell you how many links that Wikipedia page has and how many of those links are broken.

I find it helpful because I can make corrections to broken links immediately (or, hopefully, before a page goes live). Check My Links is ideal for developers, content editors, and web designers, according to its creators.

  • Cumulative layout shift — how stable the page elements are as it loads.
  • Largest contentful paint — How quickly the user can see the largest page element.

18. Schema.org

Image Source

Search bots scrape structured and unstructured data from web pages. But the bots are not always accurate. 

Schema or structured data is a semantic vocabulary of tags that you can add to a page’s HTML to help crawlers understand the page’s content. Search engine companies created it as a unified language for structured website data.

This code helps search engines display your content in rich format (search results other than the traditional blue link text). For example, the recipes displayed below are rich results:

Schema data helps search engines show your pages for the right search query, increasing your website’s CTR and site visits.

Note that Google only uses 35 of the schema types. However, they don’t penalize you for including structured data they don’t use. Check out their rich results page to learn more about the schema types you can implement on your website.

Schema.org helps you to:

• Explore several ranking opportunities, including rich results like knowledge panels, FAQs, carousels, images, videos, etc.
• Add schema to any website page. Structure page data to help search engines easily find and categorize your website.
• Enhance your website’s appearance. This gives you a competitive edge in the SERPs.
