Performance is important in all aspects of life, and none more than business.
Oxford Dictionaries define performance as “A task or operation seen in terms of how successfully it is performed”
and this should be applied to every aspect of your business, including your website.
When it comes to performance metrics there are some key statistics you should be measuring on your website including page load speed, page size and number of requests. This is where size truly does matter.
We aim for the below performance metrics, and these are greatly affected by the number of requests and page size, but what does this actually mean? What can we do about it? Why does it even matter?
|First byte (time for server to respond)||<-0.3s|
|Render Start (starts to serve page)||< 1s|
|Load speed (time to complete page)||1-2s|
|Page size||< 0.8 MB|
|Requests (amount of items transferred)||< 30|
If it takes more than 3 seconds for a page to load the rate of abandonment is greatly increased. This can have a significant effect of the number of qualified leads you gather, the user journey, the number of sales, the time spent on the site and ultimately your conversion rate.
Google’s algorithm favours websites with fast page load speeds. The reason being that the faster a website is the more likely the user will have a positive and worthwhile experience.
If a site takes a long time to load, the elements don’t render correctly and there are lots of errors it can have a direct impact of the users impression of your company. Organisations with poorly performing websites are viewed as less trustworthy.
The larger your page size and the higher the number of requests the worse your site will perform on browsers on mobile devices. With Google favouring mobile friendly sites in their search rankings, and the rate of mobile browsing overtaking desktop internet use this is significant.
