There are a number of reasons why website performance is necessary for businesses.
Firstly, website performance is a key factor in determining whether a website is successful in achieving its objectives. If a website is slow or unavailable, users are likely to leave the site without completing their intended task. This can result in lost sales or leads, and decreased customer satisfaction.
Secondly, website performance is a key factor in search engine ranking. Search engines use a number of factors to determine the ranking of websites, and website performance is one of the most important of these. A website that loads slowly or is unavailable is likely to be ranked lower than a website that is fast and responsive. This can have a significant impact on the visibility of a website, and the amount of traffic that it receives.
Finally, website performance is a key factor in the user experience. Users expect websites to load quickly and be responsive to their actions. If a website is slow or unresponsive, users are likely to become frustrated and may even abandon the site entirely.
