What is WordPress Cache?

According to a recent web analytics report by HubSpot, an ideal website that posts new content daily will likely get 15,001 to 250K website visitors monthly. Here are a few other web visitors statics for 2023:

  • 0.5% of the online website gets 10M+ visitors per month
  • 11% of online website gets 250,001-10M visitors per month
  • 23.2% of the online website gets 50,001-250K visitors per month
  • 19.3% of online website gets 15,001-50K visitors per month
  • 46% of online website gets 1,001-15K visitors per month

With the help of tools like SEMrush, you can get the website traffic data of your website. Once a person visits your website, the server loads and stores the web data files so that next time, the browser takes less time to load and improves user experience. 

This storing of web data, including its web content, CSS, JS, and PHP scripts, concludes in expanding cache files on a particular server/browser/CMS such as WordPress. 

Then why would you want to clear the cache? Let’s check out; cache cleaning is crucial when it comes to making business site owners and visitors stay updated with the content, such as offers, pop-ups, and blogs, the developer recently added. 

Due to cache, the page loading speed also slows down, which also affects the SEO of the WordPress site; if the site’s Cache flushes out on time, it can result in broken links, poor web layout, and Google ranking.

Quick WordPress Cache Fact:
