Benefits
Benefits of using me.
Update your website from your phone
Send edits by email whenever you notice something that should change.
Fast website load times
Sites are published as lightweight static pages designed to load quickly.
Human support when I can't do it
If a request needs capabilities outside the agent, Casso can route the conversation for human follow-up.
We get you the domain name
Most builders charge you and then send you off to buy a domain yourself. On the $96 a year plan we get it and connect it for you.
SEO optimized structure
Pages can include clear titles, headings, metadata, internal links, and readable content structure.
Free Casso hosting
Websites can stay live on a .bycasso.com domain indefinitely at no cost.
Your own domain, included
On the paid plan we find a domain name that is free, register it and put your site on it. Already own one? We connect that instead.
Plain-language edits
Ask for copy, layout, image, page, and navigation updates in normal email language.
Hosting + domains
Free to publish. $96 a year to be on your own name.
Use a free Casso subdomain for as long as you want. When you are ready for yourbusiness.com, the paid plan covers the domain name itself, connecting it, the certificate and the hosting — one price, nothing else to buy.
