In a previous post, I presented a massive list of free SEO tools that can help you accomplish various SEO tasks (e.g., backlink investigation, keyword research, etc.). I received a lot of positive feedback about that list, but people consistently requested more SEO analysis tools.
Since I’m a man of the people, this post is completely dedicated to SEO analysis tools. For each tool, I’ve provided a brief overview of its functionality, and I’ve also included helpful screenshots along the way. After you finish this post, your SEO analysis toolbox should be overflowing with goodness!
Now, let’s get started…
WooRank is a freemium tool that provides an “instant website review.” Without a premium account, you are only allowed to generate a limited number of free reports, but you are able to view previously generated reports. Also, the tool currently offers a 7-day unlimited free trial, which gives you access to unlimited reviews. If you’re interested in purchasing a plan, the cheapest one is $49/month.
Here’s the summary view from a WooRank report:
The report is divided into the following 8 sections:
- Marketing Checklist – These are the most important action items for your site.
- SEO – This section checks if the site is following various on-page and off-page SEO best practices (e.g., appropriate title and description, keyword consistency, backlink count, www/non-www canonicalization, XML Sitemap usage, etc.).
- Mobile – The mobile version of your site is displayed, and the site’s adherence to mobile optimization best practices is evaluated.
- Usability – This determines if your site is user-friendly by evaluating various usability best practices (e.g., the existence of a custom 404 page, above the fold content, structured markup, etc.).
- Technologies – This section investigates miscellaneous aspects of the site (e.g., W3C standards compliance, speed optimizations, etc.).
- Social – This quantifies your site’s popularity on social networks, and it reproduces various social data found elsewhere (e.g., profile information on Facebook, Twitter, Google+, etc.).
- Local – This section presents your site’s listings in local directories (e.g., Yelp, Foursquare, etc.) as well as online reviews associated with those listings.
- Visitors – This measures the site’s popularity based on various traffic estimates.
SEO Site Checkup is a free SEO analyzer that analyzes your site (and an optional competitor) using 45 individual checks in 6 different categories. Based on the results of those checks, the tool generates a summary, which includes a numerical score for the site and a count of the failed checks:
Below the summary, the tool presents the results of the 45 checks using the following sections:
- Common SEO Issues – This section includes a wide variety of SEO checks (e.g., keyword usage in important markup areas, an appropriate code to text ratio, the existence of a robots.txt file and an XML Sitemap, HTML standards compliance, SEO-friendly URLs, etc.).
- Speed Optimizations – This covers various load performance-related checks (e.g., page size, compression, caching, minification, server speed, etc.).
- Server & Security – This section identifies a few important hosting and security characteristics of the site (e.g., proper canonicalization, appearance on suspicious blacklists, providing unnecessary access or displaying potentially sensitive information, etc.).
- Mobile Usability – This checks if your site is mobile friendly by providing a snapshot of what it looks like on mobile devices and looking for media queries.
- Social Media – This section helps quantify the site’s social engagement by providing share counts for various popular social media sites.
- Semantic Web – This tries to determine if the site is using structured data (e.g., schema.org microdata).
#3 Site Auditor
Site Auditor is one of the SEO tools provided by Raven Tools as part of their Internet marketing solution. After you run Site Auditor on your website, the tool presents a report that summarizes its findings.
Currently, Raven Tools offers a 30-day free trial for Site Auditor (and all of their other tools). Once your free trial expires, the least expensive premium plan is $99/month.
Here’s an excerpt from a Site Auditor report:
The report is broken into 9 different sections:
- Visibility – This summarizes your site’s visibility for search engines (e.g., which pages are blocked by robots.txt and/or robots meta tags, which pages cannot be found, and which pages return redirects).
- Meta – This section identifies the site’s most important metadata and corresponding duplication (e.g., duplicate titles, duplicate meta descriptions, etc.).
- Content – This presents important characteristics for your site’s textual content (e.g., title, link counts, word count, existence of internal duplicate content, etc.).
- Links – This section lists information about the site’s internal and external links (e.g., anchor text, if the links are broken, if the links are nofollowed, etc.).
- Images – This shows your site’s images and corresponding metadata (e.g., filename, alt text, title text, size, etc.).
- Semantics – This section offers information about the site’s headings (h1, h2, and h3 tags) and schema.org microdata (items and types).
- Desktop Page Speed – This gives your site’s desktop page speed results: a numerical score and corresponding speed-related best practices (e.g., avoid page redirects, enable compression, reduce server response time, etc.).
- Mobile Page Speed – This section displays your site’s mobile page speed results: a numerical user experience score, a numerical speed score, corresponding user experience best practices (e.g., size content to viewport, size tap targets appropriately, etc.) and speed-related best practices.
- Crawl Comparison – This compares different crawls of the site (performed at different times) to evaluate how the site’s issues are changing over time.
Unlike many of the other SEO analysis tools on this list, which focus primarily on your site’s SEO activities, Marketing Grader digs a little deeper into your company’s online marketing strategy.
Here is an example of a Marketing Grader report:
The report focuses on five areas of your company’s online marketing efforts:
- Blogging – This section investigates your blogging activities (e.g., does your site have a blog, does it have social sharing buttons, etc.).
- Social Media – This section evaluates your social media activities (e.g., are you using Twitter and Facebook, do you link to your profiles from the homepage, etc.).
- SEO – This section checks a few important on-page and off-page SEO ranking factors (e.g., titles, descriptions, backlinks, etc.).
- Lead Generation – This section analyzes the effectiveness of your landing pages (e.g., are you using forms to capture leads, are you using analytics software to measure your results, etc.).
- Mobile – This section determines if the page is mobile-friendly (e.g., are you using @media queries or a mobile stylesheet, do you have a meta viewport tag, what does the page look like on mobile devices, etc.).
Site Analyzer is another free SEO analyzer, and it presents 71 data points, which are organized into 5 groups. After you perform an analysis on your site, the tool presents an overview, which includes a global score as well as accessibility, design, texts, multimedia, and networking scores.
Here is an example of the tool’s overview:
The tool also presents an in-depth view for each of the overview sections:
