What is the significance of the RUM Speed Index for the sustainable success of a web presence?
From SEO’s point of view, web presences with short loading times are clearly preferable. If a website loads quickly and is presented to the visitor without delay, the website will be visited and used regularly. However, if a website takes a long time to load completely, this circumstance can have some extremely negative consequences.
For example, it can cause visitors to become impatient and check that they have typed in the correct URL or, in the worst case, even abandon the page load. This can cause websites to lose visitors very quickly.
Another negative consequence of too long loading times is the inoperability of the accessed website. While all visual elements of the website, such as photos, videos or control elements, are already loaded, however, no interaction with the page is possible. This also usually leads to the website being used less readily, which in many cases has a negative effect on visitor numbers.
From the information provided by the RUM Speed Index
, it is possible to see whether optimisations need to be made to the website in question. If loading times are to be reduced, it is advisable to carefully check the size of each resource that is loaded as part of the website. Reducing the size of audio, video and image files by converting them to a different format can go a long way in improving the loading times of the website. Removing background images can also speed up the loading process.
