What is an SEO audit? Do you need one?

An SEO audit checks how well your website is optimized for search engines. An audit looks for errors that prevent your site from ranking high in search results. At the same time, it looks for opportunities to gain more visibility. If you would like to improve the visibility of your website, you should conduct an audit!

You can use an SEO audit to win new customers, create a case study, or simply to get under the hood of a website to see how it works. An audit can reveal a lot. Find those things that are easy to resolve first. Quick Wins! (Low Hanging Fruit).

The Big Picture. Quick and Dirty Audit. (On-Page/Tech SEO circa 120 minutes.)

An off-page SEO audit and a keyword audit are not included in a simple web audit. Focus on the on-page and technical aspects first. This may lead to you being asked to do the off-page and keyword audit anyway.

Why do an SEO audit? To create an overview or as a pre-sales tool. Use the opportunity to evaluate a website as an offer for more work. At worst, you’ll have a case study for your website. And that’s a good exercise.

What should you measure? What is the goal, target audience, strategy, of the website?

Important! Ask customers first: for what do you want to be found? by whom? where? and why? Concentrate on analysing the customers and not on ‘average values’.

How often should you conduct an SEO audit? A least quarterly when running your own website, or that of a client.

Wrapping up Your SEO Audit

SEO audits teach good website housekeeping, but here is no perfect audit.

Regardless of audit, remember that there are really only three things important for your SEO:

  • + Good Content
  • + Page Experience
  • + Relevant and Helpful Links

Content: Helpful, relevant content that makes decisions customers need to make easier.

Page Experience: A good experience is remembered — also a bad one. If getting it is easier, people will choose a poorer product over a better one. Make sure the UX is simple and good.

Links: Not just any links. Links that support the first two things. Citations. Links with authority. People you know and who know your brand builds brand loyalty and trust.

And don’t forget – SEO means getting found! Now, sometimes that’s an accident. Don’t shoo the person from your shop, your website, OR your social media. It happened for a reason. Win them over! #SEO
