In case you don’t know Sitebulb (yet)…

How to audit a site with Sitebulb step by step

Below are all the steps you need to take to perform an SEO audit with Sitebulb.

☝️ Sitebulb is indeed an awesome SEO auditing tool but you need to still apply your common SEO sense while analyzing the crawl results. Site crawling tools are there to show you possible issues and often highlight the elements that are not real issues. It is your job as an SEO to decide if a given “issue” is really an issue.

Sitebulb, fortunately, makes it easier to accurately assess potential issues by providing explanations and further reading next to every SEO hint it gives.

I don’t think you need to know anything more. Let’s start the audit!

Every SEO element analyzed by Sitebulb provides these explanations. Even though I am an experienced technical SEO, I learn new things about SEO every time I do an SEO audit with Sitebulb.

Let’s analyze one example hint for my site regarding broken internal URLs.

SEO audit details in Sitebulb

The explanation Sitebulb gives here is clear and I can navigate directly to the affected URLs. However, if I don’t understand this hint fully, I can go to the further reading link which points to the entire article explaining what broken internal URLs are, why this issue is important, and how to fix it.

I don’t need to google anything! It’s all here. Amazing!

What I REALLY like about Sitebulb

I’ve been using Sitebulb for some time already and have performed quite a few technical SEO audits with its help. There are a few things I especially like about it:

  • Sitebulb automatically saves your crawl data You don’t need to manually save or export the crawl data to be able to get back to it later. All you need to do to get back to any crawl is to simply open Sitebulb, navigate to the project you are interested in, and click Latest Audit.
Projects in Sitebulb
  • Sitebulb has 18 different default user agents and you can even define a custom user agent.
Project settings in Sitebulb
  • Sitebulb lets you analyze the speed of all the web pages without the Google PageSpeed Insights API.
  • Sitebulb does a great job dividing issues into different categories. I really love how Sitebulb divides issues into different priorities (critical, high, medium, low, insights) and different types (issues, potential issues, opportunities). Sitebulb is very accurate when it comes to assigning priority to specific issues. It does not unnecessarily alert me that, for example, my site contains a critical error because the title tag of the contact page is too short.
SEO hints in Sitebulb
  • Sitebulb has both dark and light modes. With just one click you can turn the lights off and on.

  1. Hi Olga,
    I have just met sitebulb. I can say that it offers a better experience than a few other crawl tools I have used. I get a warning as a result of the crawl. contains invalid HTML elements. i have removed the facebook pixel noscript part but issue was not resolved.

    When I enter a url it gives a warning like this.
    “This URL contains DOM elements in the head that could have broken the causing data within it to be invalid, for example canonical and robots directives.”
    Invalid elements: TİTLE,LİNK,NOSCRİPT,İMG

    frankly i am confused. these elements are the elements that are on every page. Why would it be invalid? I hope you can declare an opinion.

    thank you very much

  2. Epic piece, Olga! Thanks for putting this together. You’ve reminded me about features in there that even I’d forgotten about!

    • Thank you, Geoff. That’s awesome! 🙂 Every time I do an SEO audit with Sitebulb, I discover new cool features. It never stops!
