Yes, many white label portals let you add content sections to your site, though the extent depends on what your plan includes and what you want to display. You can typically customize pages to show destination information, travel guides, blog posts, or tips that help your customers plan their trips. Some portals make it easy to add this content yourself through a simple editor, while others let you connect your own content from elsewhere on the web. The key is that you control what appears on your site and how it looks, so it all matches your brand.
What you can do varies by your plan and the portal you choose. A basic plan might let you add simple text and images to a few pages, while a more advanced plan could include richer content options, the ability to pull in feeds from other sources, or templates designed specifically for travel content. Some portals also offer a library of pre-written content about popular destinations that you can use or customize for your customers. You should check what content features are included in your plan and whether you can add more if you need them later.
Keep in mind that while the portal handles displaying the content, creating and updating that content is up to you. You will need to write, photograph, or source the guides and tips yourself, or hire someone to do it. The portal just gives you the tools to organize and present it alongside your booking features. Talk to your provider about which content options are available in your plan and how much flexibility you have to add or change content over time.
