Every business owner or digital marketing professional should understand how to conduct an SEO audit by checking all the important ranking factors used by popular search engines like Google, Bing and Yahoo.
An SEO audit tool makes this super easy by scanning your website and revealing the necessary fixes and optimization opportunities.
If you’re looking for the best SEO audit tool to take your SEO to the next level, then you’re in luck.
In this post, you’ll discover the top SEO audit tools (free and paid) for 2021. Whether you’re auditing on-page, off-page or technical elements, these tools will provide clear insights on fixes you need to make to improve your or client’s website’s rankings in the SERPs.
What an SEO Audit Should Be
First, an SEO audit should be thorough and comprehensive. A proper SEO audit should uncover both content and structural components affecting your website’s visibility and rankings.
Also, SEO audits should be easy to interpret. As a business owner or digital marketer, you should be able to easily connect the dots about how the identified SEO issues are affecting your online presence. Likewise, all recommendations should relate exclusively to your overarching marketing goals.
Finally, the recommendations from your SEO audit should be actionable. There should be a clear path from start to finish, clearing stating efforts associated with each recommendation and the kind of results to expect. You should be able to distinguish between low impact and high impact fixes that will move the needle.
What is an SEO Audit Tool?
An SEO audit tool is a piece of software that helps you analyze your website’s performance in relation to best practices.
Conducting an SEO audit is the first step to creating implementable plans that can help you improve your organic rankings and drive more traffic to your website.
A comprehensive SEO audit can reveal:
- Technical SEO issues, such as duplicate content, improper redirects and poor mobile experience
- On-page SEO issues such as title tag issues, meta description, low text-to-HTML, broken internal and external links and broken images
- Website structure issues, such as navigation issue, and mobile friendliness
- Potential off-site problems – broken backlinks, no-follow links, RSS feed and inconsistent citations
- User experience issues – page load speed, mobile friendliness, and navigation issues
- Content gaps and opportunities
- Competitive marketplace insights
Why It’s Important to Audit Your Website
Your website is the online equivalent of your physical store or company. So, it’s important to have it checked regularly to ensure that everything is in order.
It’s also important to note that search engines like Google are always rolling out algorithm updates to improve user experience. This means that you need to keep an eye on the latest search engine best practices, and comply with local SEO best practices if you run your own local business that rely on real foot traffic of customers.
Considering the ever changing nature of the SEO landscape, it’s recommended that websites are audited at 3 times in a year. Doing this allows you to spot any issue on time and fix them immediately.
