To create a hyperlink, linking a word or image to open a new web page, you'll first need to copy the destination URL. Open the webpage you want to link to in your browser and copy the URL (web address).
Now go to your website admin and open the page, product or category with the item you want to link. In the text section, highlight the word or image that will link to the new web page. Then you can either right click and select insert/edit link, or click the chain icon below the "underline" icon.
A new window will appear and you'll paste the destination URL into the "Link URL" field.
Then click "insert" and the window will close, and you can click the green Save button.
