The process of getting your completed web pages to your host server is called uploading/publishing. The web design product you use may have an upload/publish function and most hosting services have a control panel/dashboard that includes a file manager that can be used to publish/upload. If not, there are FTP (File Transfer Protocol) software products available that will upload/transfer your files to your host server (see the Links page). NOTE - Some web design software upload/publish functions will not work with all hosting companies. If this is the case you can use FTP software to do the uploading/publishing.
If you use your web design program to upload/publish your web pages it will probably upload any needed images, media, and other non-html files in addition to the html pages. If you use FTP software you will have to select all of the non-html files in addition to the html files. Depending on the design software you use, the non-html files may have to be in separate folders (e.g., an "image", "files", and "geometry" folder). The folder names may vary with different web design programs. Remember that your home page should have "index.html" or "index.htm" as the file name.
Be sure to thoroughly test the website after the upload to be sure all necessary files were successfully uploaded and work correctly. When you need to update a web page you can just upload that page (and related files) and the upload will overwrite the old files. NOTE - Some web design software products save web pages in their own unique file format and automatically convert the files to web format files (e.g. HTML) when the upload/publish function is used. If you are going to use FTP software for your uploads you will first need to do a save-as/export for the web page files to create HTML files. It is a good idea to save these files in a separate folder to make the FTP file selection easier as the web design unique format files do not need to be uploaded. Also, if you use FTP software for your uploads you must also upload files and graphics used by the webpage. These may be in separate folders (e.g., "files" and "images" folders). If so, the complete files should be uploaded to the folder that contains the HTM/HTML files.
CAUTION: Hackers/scammers have software that watches the Internet for website uploads and may be able to steal your FTP password when you do an upload. Then they can change the content of your website and/or use you website to scam emails to millions of people. It usually takes several uploads before a new website is the way you want it to be. It is a good idea to change you FTP password after you complete the new website uploads and changes. Changing you FTP password again after future updates is also a good idea. If someone does hack your website you may need to change your FTP password, delete everything in your website folder, re-upload your website, and change your password again. Before you do this check with your hosting company support personal as there may only need be changes made to certain folder files.
