SEO checkers help you optimize your website for better visibility and increased organic traffic. In this guide, we’ll explore the benefits of using SEO checkers, the key features to look for, and some of the best tools available in the market.

In the competitive world of digital marketing, ensuring your website ranks high on search engine results pages (SERPs) is crucial.

Whether you’re a seasoned marketer or just starting out, this article will provide you with the knowledge you need to make informed decisions and take your website’s SEO to the next level.

First, let’s clarify what an SEO checker is.

I like the immediacy: you can instantly optimize pages. Beginners can learn by doing.
I’ve dealt one-on-one with AIOSEO support and believe they are among the best. They’re staffed with experienced software engineers and will solve and advise on any related situation, no matter how complex.
In my experience, if you’re willing to go beyond the crowd in producing quality content, using AIOSEO can help push you to the top of rankings.

How Much Does All in One SEO Cost?

All in One SEO (AIOSEO) starts at $49.60/yr. That’s an excellent deal, given many SaaS products charge monthly fees. It’s largely considered one of the best SEO marketing tools available, and for good reason.

There are multiple tools packed into AIOSEO, and you’ll likely never use them all.

In addition, every month, AIOSEO releases new features and improvements to their plugins. Often, these are based on customer ideas. It’s refreshing to see a small business this responsive to users.

Free version? There’s also a free, limited version of All in One SEO. If you want this, it’s crucial to download it from the link I provided. Why? There are lots of people offering “free AIOSEO” online.

In addition to legitimate websites that have affiliate deals with AIOSEO, and also point to WordPress.org, there are other sites offering “nulled” or “cracked” plugins. Cracked plugins are infamous for containing malware.

If you get one of these nulled plugins, the AIOSEO support team cannot assist you. They can’t solve malware problems created by software that’s been tampered with.

2. AIOSEO SEO Analyzer: Free Online SEO Checker

This is a free SEO analysis tool provided by All in One SEO. You can access the SEO Analyzer here.

You can use this to get an instant analysis of any web page including competitor pages.

The tool includes features from the SEO Analysis tool included in the AIOSEO plugin.

My Experience

Add a URL to the Analyzer and you get a rapid analysis.

There’s an SEO score at the top which will increase as you act on the recommendations.

The analyses are grouped by convenient labels including Critical Issues and Recommendations. That enables you to prioritize what needs fixing first.

You can also tab between:

Basic SEO
Advanced SEO
Security

Marketers will like the fact you can download the Analyzer report as a PDF. The report could be used in pitches to potential or current clients.

What I like

This SEO checker is free and provides an introduction to the plugin’s capabilities.
Using it doesn’t require a sign-up or giving credit card information.
The checks tell you what to do to improve your page.
Includes advanced SEO and loading speed analysis.
As a bonus, the page’s security is analyzed including whether or not Google has flagged the site for malware.

3. AIOSEO Analyzer: Free Chrome Extension

Next we have a 3rd tool from All in One SEO (AIOSEO). This one also has the word “Analyzer” in the title, which can be a bit confusing.

This tool is a free Chrome extension that has quickly racked up many 5-star reviews since it was launched. This is one of my favorite SEO checkers because it’s quick and easy to use.

My Experience

Like all Chrome extensions, this one takes seconds to install. Navigate to any web page, click on the circular AIOSEO extension icon, and you’ll see an overlay with various analyses that you can tab through.

This extension comes bundled with content checks (such as h-tag use) as well as technical SEO checks (such as robots.txt file presence).

This is a nice tool for doing fast checks of basic SEO issues. There’s no need to login to WordPress and it works on any site, no matter the content management system.

Editors can use it to view content outlines, or check for presence of alt tags, use of h-tags, and titles and meta descriptions.
Marketers can use it for fast analysis during discovery calls with potential clients.

Note: to check whether a site has a sitemap, you’ll click on the sitemap.xml hyperlink at the bottom of the extension window. What this does is append sitemap.xml to the domain you’re analyzing, no matter the page you’re on.

While this works most of the time, for some sites, like cnn.com, there’s no sitemap at that location.

What I Like

Attractive, clean interface.
Getting instant results. No login required.
The compact outline displayed for each page.
You can check for the presence of a robots.txt and an XML sitemap file. These are hyperlinked so you can click through to view the files.
Clickable checks for internal and external links.
Includes Image SEO, schema, and OG (social media) tag checks

My Experience

Example of use: I discovered a website template came, ‘out of the box,’ with the blog omitted from the sitemap.

Additionally, the blog landing page had the “noindex” tag applied to it, preventing it from appearing in search results.

Knowing this enabled me to correct the problem within a few minutes.
