If your website is “mysupercoolwebsite.com” and I type “mysupercoolwebsite.com”, do I see your website immediately, or do have to look at a blank screen for a while before your website actually pops up. If your website is fast, it pops up quickly. If it’s slow, it doesn’t.
There are lots of reasons that a website can be slow. However, if your website is less than 10,000 pages and built on a modern website platform (e.g. HubSpot, WordPress, Wix, Squarespace, Shopify, etc. etc. etc.) you’re probably fine.
