I’m sure a lot of people have run into all sorts of problems due to forgetting to set a BaseURL, so today, we’re going to talk about Hugo’s BaseURL and what known issues it can cause.
Known Issues Without BaseURL
Unable to Preview Images When Making Social Sharing
Without setting correct BaseURL, you’ll unable to preview the images when making social sharing, this is because social media platforms do not resolve images that are not absolute URLs.
Search Engine Failed to Index the Sitemaps
Without BaseURL, the sitemaps URLs are all relative, and that causes search engines failed to index your pages.
Conclusion
As noted in issues above, the BaseURL is very important, which is used to generate absolute URL for your site resources, such as sitemaps, images and so on, so that they can be parsed by other services and platforms correctly.
