We completed more than one billion audit checks on websites in the past quarter and I’m going to share with you the practical findings and actionable insights discovered from this.
Website health is imperative to search success.
From crawling and indexation, through to site speed and mobile friendliness, a website with poor health will not perform anywhere near its potential online.
We believe in this statement so much that, as a company, we created a means to crawl, test, audit, report, prioritise and implement the most important technical website health checks. Through this we’ve completed more than one billion audits.
In fact, we reached the one billion-mark in just over a month.
From this wealth of data we established website audit scores to benchmark the health of thousands of sites (individually and cumulatively). An individual site sample can be seen below:
Using our own deep data platform, we set up audit categories and rules, and applied weightings, thresholds and other contextual data to apply actionable meaning to the provided data.
Apollo Auditor (our audit bot) has saved the work of an estimated 3 people per year so far, with the complexity, frequency and effectiveness of technical website reviews being continuously completed.
In collaboration with our search experts and efficient technical reporting functionality (a large element of this included prioritisation of failed audit checks, as well as insights into implementation actions needed) we can effectively improve site health.
Adding instant notification functionality means that our experts (and customers) can get updates on site health 24/7, for support when it’s needed the most.
Through Apollo Insights (our deep data platform) we completed technical website audits covering the following categories:
Within these categories we established a number of rules by which a website could pass or fail.
We wanted to be able to benchmark category health and severity (plus other areas), and make improvements based on impact potential value.
On top of this, having control of refinement means that Apollo Auditor can ‘learn’, based on changing scenarios (for example, changing a threshold for audit failure based on latest Google updates).
Lessons from this data will continue with every crawl and check. However, there is a lot we can already share with you:
Comparing the top 10% of technically healthy websites to the bottom 10% (in this case external, non agency sites, to support less ‘active’ likelihood of link building) the average difference in link volumes is over 750%.
The bottom 10% attracted a total of 1903 average links, compared to the healthiest sites that attracted 14,431 backlinks.
When looking at the top and bottom sites for technical performance (in this case agency serviced sites regardless of specialist service provided) the healthiest 10% received 33% more traffic from SEO.
Dramatically slower in fact.
The healthiest sites are 22% faster on mobiles and 23% faster on desktops.
From a sample of thousands, I can categorically state that a website without active Search Engine Optimisation is technically unhealthier.
On average, website health suffers by approximately 15% without active SEO in place.
The lowest performing websites for technical health were 30% unhealthier than the respective lowest performing websites with SEO.
The main action from this post is to think about your website health.
How do you measure your website’s health at the moment?
Do you have defined intervals to complete website health checks?
I would love to hear your thoughts about this post as well as your successes from improving technical website health – tweet me!
