Some of your content needs to be corrected for grammar & syntax. For example: “Next thing you need to decide when starting a website is what site building platform you’re going to use, if any.” should be “The next thing you need to decide when starting a website is which site building platform you’re going to use, if any”. I noticed that you omit the word “the” too frequently, you need to add it to every sentence that needs it.
You also have a lot of capitalization errors and inconsistencies that also need to be fixed. For example: “Step #1: Choose your website Platform”. Why is “Platform” capitalized when the other words aren’t? Either capitalize every word, or only capitalize “Choose” so it says “Choose your website platform”. Be consistent so it’s not confusing for readers, and so that your content becomes trustworthy—if any of the English content on your page isn’t 100% impeccable, then some readers may be unlikely to trust your content.
Basically, you have a lot of English errors on the page, which should all be fixed before the site is launched.
There are also a lot of errors in your HTML code which should also be fixed before launch, you can use the W3C Validator to find them: https://validator.w3.org/
