Kitset keeps two copies of your website. There is the one you are editing, which only you and anyone you send a preview link to can see, and there is the published one, which is what the public gets. Pressing Publish copies the first over the second.
This is why you can experiment freely. Delete a whole section, try a colour you are not sure about, paste in three paragraphs and cut them back to one. None of it reaches a customer until you decide it should. It is also why nothing is ever lost: every version you publish is kept, so an earlier one can always come back.
The one thing that stops a publish is billing. Kitset does not ask for a card while you are building, so a brand new site asks for one the first time you try to go live. That is not an error and you have not done anything wrong.
It takes about a minute. Publishing is not instant, and that is normal. Your page is copied out to servers around the world so it loads fast for everyone, and that takes a moment to finish.
Step by step
Open the editor and read the page as if you were a customer.
Check the phone view as well. Most people who visit a small business site are on a phone, and it is the view most people forget.
Look for anything still showing our example wording. The editor marks those for you.
Press Publish, top right.
If you have not added a card yet, you will be asked for one now.
Kitset is $10 a month. Nothing goes live until there is a card on the account.
Wait about a minute, then open your site in a new tab and read it there.
Reading it on the real address, rather than in the editor, is how you catch the things your eye has stopped seeing.
If it does not go to plan
I pressed Publish and it asked me to pay.
Expected on a new site. Go to your dashboard, open Set-up, and the plan card is in there. Once the card is added, publishing works from then on without asking again.
I published but the page looks the same as before.
Your browser is almost certainly showing you its saved copy. Hold Shift and press reload, or open the page in a private window. If it looks right there, your site is fine and it is your own browser being stubborn.
Can I undo a publish?
Yes. Open History in your dashboard, find the version from before, and put it back. Nothing you publish is ever thrown away.
