Getting your website to rank on the first page of search engines requires you to publish great content and build authoritative links. But these won't matter unless you have a site that Google can crawl and index. So, ensuring your website doesn't have issues preventing search spiders from finding its pages will be critical to its long-term success.
Below are search engine optimization (SEO) audit tools to choose from, arranged alphabetically. Each has unique features to determine SEO issues affecting your site so you can fix them and make crawling your website possible. Let's begin!
1 - Ahrefs Webmaster Tools
Best for: Site owners looking for a free tool to analyze their website for technical SEO issues.
Ahrefs launched this free SEO audit tool to help users identify problems preventing search engines from finding their sites. After crawling your site, the tool shows you its Health Score based on the number of issues your website has based on their severity. The more critical problems your site has, the lower your Health Score is.
From here, you can check your site's top issues, the pages affected by the issues, and ways to solve them.
Ahrefs Webmaster Tools also shows internal link opportunities for related pages that don't link to each other. It also tells you which anchor text to use for each suggestion to maximize the impact of your internal linking strategy.
You can dig deeper into the SEO audit by looking at the Reports page. It reveals your site's indexable, non-indexable, and broken pages and links, giving you a complete view of how Google sees your website. It also gives you access to its meta tags, redirects, and Core Web Vitals performance, providing further insights and ideas on optimizing your site.
To use this tool, sign up for an account and connect your Google Search Console with it. However, you'd want to consider using Ahrefs' other features like Site Explorer, Keyword Explorer, and others to power up your SEO efforts. Price starts at $99/month.
In particular, Ahrefs' backlink profile checker is one of the best in the industry. With a 35 trillion external backlinks history in its database, you can get accurate insights about the quality of links your site has. Using the data here helps you identify backlinks you must track and prioritize while ignoring and possibly disavowing the worst ones.
2 - Google Search Console
Best for: People looking to understand how their site pages perform on Google search, which queries each is getting impressions for, and what indexing issues are affecting their site's overall performance.
Think of Google Search Console (GSC) as a free keyword rank-tracking tool. It shows you which queries your pages appear on Google search, the number of impressions your pages get, and how many people click on them on SERPs. You can use this information to identify and prioritize your best-performing pages while fixing pages that aren't generating your desired traffic.
It can also show your CTR and impressions on Google Discover if you optimized your site pages to appear there.
Under the tool's Indexing tab, you can see indexed and non-indexed pages on Google. It also explains why the search engine didn't index the pages so you know how to resolve them if necessary.
After fixing non-indexed pages, submit them using GSC's URL inspection. This informs the search engine that the pages are ready for crawling and indexing.
To help Google search spiders find your site pages more accessible, upload all your sitemap URLs here. By making your site pages much easier to find, Google can spend its resources on your site to index them to their respective keywords.
Also, instead of running each site page on Google PageSpeed Insights, the tool's Experience tab shows which pages have good Core Web Vitals and which need improvement.
And Google Search Console pricing? It's free! Just correctly set up the tracking code you'll get after signing up for an account on your site. The tool will then gather search data about your website.
3 - JetOctopus
Among the many technical SEO audit tools in this list, JetOctopus helps make crawling your website simple and intuitive.
The tool visualizes on-page and technical SEO ranking factors, like 404s, orphan pages, duplicates, and other issues into graphs. This lets you analyze the results and gather valuable and actionable recommendations to improve your website.
The SEO audit software works as a log analyzer as well. The log file lets you know how search engine crawlers behave on your website. Upon integrating the tool with your live logs, you can see requests being made to the server by search spiders, revealing patterns and anomalies that could affect your site's performance on search engine results.
Best of all, Jet Octopus can scan large websites with thousands of pages and URLs without compromising speed and quality. In fact, you can scan an unlimited number of pages and log limits, as well as integrate with as many client data as possible, like Google Search Console, Google Analytics (GA), and others. This helps streamline determining technical issues and problems affecting your site's rankings and traffic.
You can book a demo or sign up for a 7-day free trial to learn how JetOctopus can help your SEO audit needs. After the trial, you must shell out at least €160/month or €120/month paid annually to crawl 100k pages (or 50k JS crawled pages) and 1M log lines. The price increases if you want more pages to crawl and log lines to analyze in a month.
4 - Lumar (formerly DeepCrawl)
Best for: Enterprise SEO agencies that want to provide clients with easy-to-understand audit reports that get all their stakeholders on board and help gather suggestions on making their sites more accessible and compliant.
Enterprise companies like Adobe, Microsoft, and others use Lumar to help align their various stakeholders using metrics like technical SEO and website accessibility to access the health of their websites.
The tool has one of the fastest web crawlers thanks to its serverless architecture design, giving Lumar greater flexibility when crawling sites of varying sizes. The platform then generates reports using the gathered data to provide users with SEO analytics and opportunities tailored to the site's issues
If you're a stickler for website accessibility and compliance, Lumar gathers the top accessibility issues your site has. This includes having duplicate descriptions, missing image alt texts, insufficient text contrast, and more. The tool takes all this information and shows your site's into three accessibility scores: A, AA, and AAA. The higher the scores across these three measurements are, the more accommodating and inclusive your site is to PWD users.
Over time, your website's health may accumulate issues with changes made by your team. To help you stay on top of them, Lumar's automated QA testing thresholds help eliminate mistakes and errors going live on your site. Integrate this feature in your web developer's continuous integration and delivery pipeline to help your team quickly catch and resolve errors.
You must request the tool's custom prices from the site's pricing page. The fee depends on factors like your website's size, needs, audience, and more.
5 - Netpeak Spider
Best for: Site owners and SEOs looking for a budget-friendly but powerful SEO audit tool that can scape data from other websites.
Netpeak Spider is one of the few desktop-based tools in this list that creates SEO audit reports for users. Enter your website URL on the tool to analyze it across 100+ factors in minutes. This helps you easily identify issues requiring your utmost attention to improve your site's search engine rankings. You can also bring in data from GA and GSC to gather all website data into a single dashboard report.
If you're running an agency, you can export client reports into white-label PDF files complete with your logo and branding.
Aside from website audits, Netpeak Spider can scrape data from other websites using over a hundred conditions. This helps you reverse-engineer your competitor sites' best-performing pages and replicate their content structure on your site to achieve success.
As a tool you need to install and run on your computer, the speed of the SEO audits depends on your specs. The faster your RAM and processor are, the sooner the SEO analysis will be complete. However, you can only access the reports where you saved them in your computer or cloud storage. This could be a problem if you jump from one computer to another since you have to always save a copy of the reports on the cloud.
Netpeak Spider costs as low as $7/month, paid annually (or a lifetime license of $168) to scan 200,000 URLs and gain access to its essential features. Higher plans give you unlimited URLs to crawl, custom website scraping, third-party app integration, and white-label reporting.
You can also bundle Netpeak Spider with Netpeak Checker, an in-depth SERP scraping tool, to unleash the power of your SEO audit campaigns.
Best for: SEO companies hunting for a safe, secure, and comprehensive SEO audit tool that can crawl any website type and complies with GDPR (with its log file analyzer).
An industry-leading technical SEO audit tool, OnCrawl helps you find and fix on-page SEO issues affecting your site performance. It also gathers and segments information about your site pages, like product pricing, implementation of AMP, publishing dates, and others.
To help OnCrawl find all the pages you want to locate and analyze your site, you can customize the website crawler to initiate JS crawling, DNS override, and more. All the data it collects, even from third-party tools, helps you determine how you want search spiders to crawl your pages and which ones they should index on search results.
Its log analyzer feature determines and analyzes requests made by search bots and users from your site servers. First, OnCrawl saves the log files in a secure FTP space in observance of GDPR compliance. They don't go straight to the application and expose your visitors' IP addresses. Now, since log files are difficult to understand, OnCrawl segments the data and presents them to users with actionable recommendations to help make changes that will improve your website's performance.
People building their own dashboard to host website data and present them to teams and clients can use OnCrawl's open rest API. It gives you unlimited access to its data so you can aggregate and present them to users according to your preferences.
OnCrawl offers three plans to choose from. Explorer gives you a 100,000 URL quota a month for a single project. Business Plan lets you manage two projects and gives you 500,000 monthly URL quota. Finally, Infinite and Beyond package gives you a custom number of projects and URLs to crawl in a month. It also provides you access to its data and log analyzer features. Request for a quote from the site for the price of your desired plan.
7- Raven Website Auditor
Best for: People in search of an all-in-one SEO tool with a robust site audit and client reporting features.
Raven is a collection of SEO and marketing tools to help you and your team develop SEO campaigns primed for success. Its site audit tool is responsible for diagnosing your websites for issues preventing them from ranking high on Google search, if at all. Set a recurring schedule when you want the tool to audit a website and change its crawl depth if you wish.
Once the scan is complete, Raven organizes all its findings into six buckets to help you prioritize which potential SEO problems to address first. For instance, if you're wondering why your site isn't appearing on organic search despite optimizing your site pages properly, check out the Visibility Issues bucket for the issues and their solutions. Other buckets check for issues on your website's content, incoming and outgoing links, and images.
Raven allows you to choose how to view the audit report. Instead of showing buckets, you can show an SEO audit checklist you plan on completing or sharing with your team or clients. This allows you to track your progress in fixing your website issues. Also, instead of sending the SEO audit report in PDF format, you can send them a link to the report they can view online and on any device.
Raventool's pricing starts at $49/month ($39/month paid annually) for two users, two projects, and 1,500 keyword ranking checks. The price increases along with the number of users, projects, and keywords.

Upon auditing a website, Screaming Frog looks at your web pages and metrics using factors like meta descriptions, broken links, the website's schema markup, and more to determine ways to fix your site for its SEO issues.

SE Ranking is another SEO tool in the list that offers features to help you build a custom SEO campaign for your websites. And part of assisting users to develop one is first to assess their site's current SEO performance and make the necessary fixes before moving on to the next phase of SEO. That's exactly what the tool's site audit feature does.
Upon running a complete audit of your site, you can view a general overview audit of the results from its score and top issues. Your goal is to increase your SEO score by addressing the most critical issues identified by SE Ranking. Each case describes the problem and how you can solve it. So, even if you're an SEO newbie, you can start fixing your site problems by following its directions.
Aside from on-page issues, the audit tool helps you make sense of your off-page SEO performance. You can better understand your site's Domain Metrics (DM) by looking at its backlinks and referring domains. It also breaks down the dofollow and nofollow links pointing to your site.
All this information helps you understand the quality of links pointing to your site, which can dictate the kind of link building strategy you must implement. So, the more links you get from authoritative domains, the higher your DM is.
SE Ranking also lets you download the report in PDF format and send it to your clients. Even better, create a white-label client dashboard that lets them view your site audit report and other features when they log in.
SE Ranking pricing starts at $39/month for 40,000 pages to crawl across ten projects (7,000 pages max per site). The price increases along with these limits, like keywords to track, backlinks to check and monitor, and others.

Clicking on the Issues tab, you can see the exact SEO problems Semrush found on your site. It identifies the affected pages and shows you how to fix them properly. If you're working with the team, you can send the issues as tasks in your Semrush CRM, Trello, or any Zapier app so your team can start working on them.
You can also view the historical chart for site audits. It shows the number of issues Semrush has spotted over time and how good you are at addressing these things.
