Best FREE Website SEO Audit Tools
There are a lot of useful SEO tools out there — some free, some paid — that can help you to look at your own site the way that Google sees it.
The tools listed below are all free and will give you a great snapshot of how your site is performing and identify key issues that you can deal with to help your website perform as it should.
When it comes to websites there are a few main points that need to be looked at to get your website to perform at its best online, and in the search results.
Any good website audit should concentrate on the following points:
- Can people find your site?
- How the website performs when visitors load it into a browser window?
To kick things off we always start with checking Google to see if the site even shows up…
The quickest way to do this is to perform a search in Google by typing in the following “site:your-domain-name”. This search string will return results of every page that is indexed in Google.
Website audit tool #1 – Google Analytics
Google Analytics is to the website owner like air is to the human being. You can’t live without it.
It is one of the most powerful web analytics applications available today. The fact that, like many Google offerings, it’s an entirely free.
If you’re not yet using Google Analytics, I recommend that you begin doing so as soon as possible. There is no other data source that provides high-quality and detailed information like Google Analytics. In a Google-dominated era, it’s what we have to work with. Most of the other SEO tools simply use the Google’s data through their API.
Google Analytics is a powerful application for tracking traffic patterns on your website. The fact that integrates with other Google programs, like Google Search Console, AdSense and AdWords, only makes it that much more valuable.
Considering most people already use at least some Google products, it makes sense to use Analytics, because it is such a powerful, yet easy-to-use, product.
Website audit tool #2 – Google Search Console
If Google Analytics is the air that an online marketer breathes, then Google Search Console is the food that the SEO consultant eats. This handy tool lets you add in a sitemap of all your pages and request that Google crawl you site for indexing.
The thing that we always do for a client is adding the site to Googles’ own Google Search Console.
It also helps identify any issues that Google has with your website.
For example, Google’s Fetch as Google tool allows you to see a particular URL as Google sees it, which is critical when troubleshooting for poor SEO performance. The information returned can help you modify the page in question for better results and can even help you isolate problematic code when you believe your site’s been hacked.
If you have just added a new page to you site then type ‘submit page google’ into a search bar. You paste the URL of your new page into the box provided and Google will scrape this page the next time it’s bots are available…
Website audit tool #3 – Google Page Speed Insights
It’s free but it is very powerful and can help identify issues with your site within about 60 seconds.
With this tool, you’ll get back a high-level review of your website performance. It won’t be the most detailed report, but it’s a great starting point because it gives you a list of things you can fix immediately to help improve site performance.
This SEO tool evaluates how well a page follows common performance best practices and computes a score from 1-100 that estimates its performance headroom,” according to Google Developers. That score can be Good, as in 80 or above; Medium, as in 60 to 79; or Low, as in 0 to 59.
Have a look in the HTML Improvements section to see if there are any issues in the way that Google is crawling your website and if they are having any trouble reading it properly.
Website audit tool #4 – SEMrush
SEMrush is a super elaborate dashboard that reports on the performance of domains as a whole and their specific pages. It has a free version and does not require a credit card to use it.
