Pros
- Easy-to-use interface and intuitive layout
- PPC tools help improve paid advertising performance
- Backlink tracking and strategy recommendations
- Ongoing rank tracking
Cons
- Not a full SEO auditing tool
- Missing some content strategy features
If you’re just getting into the world of search engine marketing (SEM), you may be looking for a tool that provides both SEO performance and pay-per-click (PPC) support. SpyFu is an SEM tool designed with Google Ads PPC optimization in mind, but it has a host of features useful for SEO research as well.
SpyFu’s primary tool is its competitive analysis reporting. Enter your domain and the domain of a competitor, and SpyFu will tell you how you rank against that competitor. Also, the report will provide you with both organic and PPC keywords the competitor is using to rank, giving you guidance on where to focus your attention.
SpyFu offers a free-to-use version with limited functionality but loads of useful information. In fact, for many just starting out in SEO, the free version will provide you with enough useful information to make it worth the time. However, even the lowest paid plan offers hundreds of data points you can’t access from the free version.
SpyFu Pricing & Tiered Features
Pricing for the lowest SpyFu plan starts at $16 a month and includes six months of historical data and up to 5,000 weekly tracked keywords. The Professional level offers unlimited data access and more than 10 years of historical data on your site’s performance—and the performance of competitors. Click on the tabs below to see what comes in SpyFu’s plans.
Though SpyFu isn’t an SEO auditing tool per se, it’s still a powerful competitor to some of the SEO auditing tools on the market. When coupled with SpyFu’s extensive PPC research capabilities, it becomes a worthy competitor and worth trying. You can try the SpyFu free version and get an idea of the power it offers.
Screaming Frog: Best Free Downloadable Software
Pros
- Free version will be enough for most small businesses
- A sleek, fast SEO auditing tool
- Audit up to 500 URLs with free version
Cons
- Free version lacks Google Analytics integration
- Interface can be challenging to beginners
Unlike the other entries here, Screaming Frog SEO Spider is not a cloud-based system. Instead, it is a site audit software you download and install on your computer. The immediate benefit of Screaming Frog is its speed. It works fast because it relies on your computer to do the heavy lifting, not a server-based process.
Screaming Frog quickly crawls your website, visiting every link and every page it can find. It examines the site for broken links, looks at on-page SEO factors such as headings and subheadings (H1s and H2s), and examines outbound links. That being said, the free version of Screaming Frog is not a full SEO audit tool because it lacks integration with Google Analytics, meaning you won’t know how you rank based on its reports.
Screaming Frog SEO Spider site audit software is available in a free version that can provide valuable information about why your site is or isn’t performing well on search engines. The paid version includes over 40 metrics, including custom code search and crawl comparisons to see how your site performance changes between revisions.
Screaming Frog SEO Spider Pricing & Tiered Features
The free version allows you to index up to check the site health of smaller sites and will crawl up to 500 individual URLs. However, some of the more essential features, such as examining JavaScript for speed and functionality or locating duplicate content, are locked behind the paid version. Click on the tabs below to see what comes in Screaming Frog SEO Spider plans.
Even though the free version of Screaming Frog SEO Spider lacks many of the features of a full SEO auditing tool, it provides enough useful data to make it the best downloadable SEO audit software available. Try SEO Spider for free today, or upgrade to the paid version for a great SEO deep dive.
Merkle: Best Local Search Results Simulator
Pros
- Free local search results simulator shows location-based SERPs Google or Bing users would see
- Schema markup generator
- Mobile-first index tool
- Mobile-friendly test
- Technical SEO testing tools
Cons
- Paid services are geared for large companies (and budgets)
- Full SEO audit requires using Google Analytics and Search Console
One of the more challenging aspects of SEO for small businesses is being able to see where their site ranks in local search results. Merkle provides the solution with a free local search simulator (along with several other free SEO-related tools), making it a worthy inclusion on any SEO audit tools list.
While Merkle’s services aren’t targeted toward small businesses, the free SEO audit tools available online give you the power to conduct local searches from any country, city, or ZIP code. Additionally, Merkle provides free tools for testing the mobile-friendliness of your site, a SERP simulator, and a full suite of other SEO auditing tools, all for free.
An example of results using Merkle’s local search tool
While you may find the local search tool the most valuable of Merkle’s free tools, don’t overlook the other resources in their arsenal. Spend time getting to know each tool, and you can build an effective SEO strategy for free using just their tools.
Moz Pro: Best for Tracking Rankings on Multiple Search Engines
Pros
- 30-day free trial
- Rankings for multiple search engines
- Free Online Presence Checker and Domain Analysis tools
- Insights for traffic changes, content trends, and site visitor behavior
- Priority score shows which keywords to focus on
- Improve backlink quality and identify link building opportunities
Cons
- No free plan, and a credit card is required to access the free trial
- Limits tracking to just three competitors
- Moz Local tools require an additional purchase
Google may be the biggest search engine, but it isn’t the only one. That’s not a lost point for Moz, an SEO audit tool that looks at data across Google, Bing, Yahoo!, and both Google International and Google Mobile.
Moz’s cloud-based tools track and compare your site to your three top competitors across all search engines. Moz also provides valuable keyword tracking, keyword insights and suggestions, and on-page optimization recommendations. The Moz interface is one of the more user-friendly interfaces for a full-featured SEO auditor.
Moz is easy to use but limits competitor tracking to just three competitors per campaign. That means you may be missing critical data on other competitors, especially if you’re in a crowded business space. Also, local search data is locked behind an additional product, so if you’re running a business that relies heavily on local search, Moz may be cost-prohibitive.
Moz Pricing & Tiered Features
Moz is free to try for 30 days, but you’ll have to enter a credit card to access the free trial. The free trial gives you access to most of the tools, though, and a month provides plenty of time to see if Moz is right for your SEO needs. Click on the tabs below to see the cost and the unique features of Moz plans.
Moz is the best SEO audit tool for those who want to improve optimization not only on Google, but also for Google International, Google Mobile, Bing, and Yahoo! searches. A free trial offers full access to the powerful suite of Moz SEO tools. With paid plans starting at $99 per month, Moz is a worthy competitor worth a close look at.

Pros

Cons
- No live chat support on weekends

- Useful testing features reserved for most expensive plan
When users are searching for products and services, they’re browsing search engine results pages (SERPs) full of links. How your link will stand out in the crowd impacts whether you get the clicks. That’s the impetus behind SEO Scout’s SERP simulator, a cornerstone of its SEO audit tool.
SEO Scout lets you see how your site will appear on Google SERPs before indexing. Additionally, the online software allows you to A/B test versions of pages, project the performance of different versions, and even preview how one title will perform vs another title for the same content.
SEO Scout Pricing & Tiered Features
Though there is no free version, SEO Scout offers a seven-day free trial packed with features. The Starter package includes up to 10 reports per month and 250 tracked keywords. A powerful keyword explorer makes SEO Scout a worthy competitor to other, pricier entries in the space.

Pros

SureOak’s keyword density analyzer allows you to assess any page on your website in terms of how you are using your target keywords.

GTmetrix: Most Affordable Technical SEO Audit Tools
Pros
- Free URL performance test shows technical aspects of your site or page (e.g., speed, image size, scripts, and so on) that impact rankings
- Free plan including on-demand tests and 3-month data retention
- Low cost paid plans to increase limits and add more features

GTmetrix allows users to track performance changes historically with its performance monitor. The system reports provide guidance on website performance and page load times. The most valuable tool is the website vitals score, which tells you how long it takes to load the page, for the page to become interactive, and how the page behaves while loading.
An example of a free technical SEO audit report from GTmetrix (Source: GTmetrix)
The free version includes many of the most valuable features, but you can only track one individual page on the free version. Additionally, the free version does not include mobile performance testing or global monitoring. For that, you’ll have to step up to the paid plan, which starts at $10.67 per month.
GTmetrix Pricing & Tiered Features
Though pricing is low, the biggest limitation of GTmetrix is scalability. Even the most expensive plan tops out at monitoring 12 pages, which may limit usefulness to many small businesses with larger sites. Click the tabs below to learn more about paid plans:
GTmetrix is a powerful, affordable system that’s best for smaller sites looking for a technical SEO audit tool that fits a budget. Starting at just $10.67 a month, GTmetrix is the most affordable SEO technical audit tool we’ve found. You’ll have a bit of a learning curve to apply the knowledge you gain, but with a free version tracking a host of metrics, it’s worth checking out.
Google Search Console: Most Accurate Keyword Ranking Data
Pros
- Free to use all features
- Connect it to Google Analytics (also free) to see all your data in the GA interface
- Most accurate data for how your site is ranking on Google
Cons
- Can be hard to connect and verify your website
- No competitor data
- Only minimal technical SEO data is provided (e.g., crawl or mobile errors)
Arguably, the best source for information when it comes to ranking on Google is Google itself. That’s why Google’s Search Console is considered the most accurate keyword ranking tool available.
Search Console allows users to track a site’s indexing status, search queries, crawling errors, and more. More importantly, it provides accurate and up-to-the-minute information on where your site is performing for keywords you’re tracking.
That’s not to say Google Search Console is the most user-friendly. You’ll have to manually provide some information that paid services help you gather, such as an XML sitemap. However, once added to Search Console, Google’s system will periodically re-crawl your site to check for new pages that need to be indexed.
Among the most valuable data you’ll find in Google’s reports are:
- Error pages for both mobile and desktop
- Total impressions (number of times your website appeared in organic search engine results pages, or SERPs)
- Number of times your search placements got clicked
- Exact search queries that landed your pages in SERPs or received clicks
- Ability to compare stats for different time periods to track and measure progress
More Free Tools in the Google Ecosphere
It simply wouldn’t be fair to Google (or you) if we didn’t give an honorable mention to the Google ecosphere of free products and services. Google provides an amazing array of search optimization tools, resources, and instructions for any business that needs them, all for free.
Here are some worth adding to your SEO and site auditing toolkits:

All Google tools in Search Console, Google Trends, and more are free to use, and Google provides ample education on how to use its products through a rich knowledge base and hundreds of video tutorials.
