Yes, Google can rank one-page websites in its search results. They don’t inherently penalize them for having just one page. However, it’s important to understand that they might be at a disadvantage compared to websites with multiple pages for reasons like:

• Less content: One page limits the amount of information you can provide about your topic, making it harder to target diverse keywords.
• Fewer backlinks: Backlinks from other websites help your site rank higher, but with fewer pages, opportunities to build backlinks are limited.
• User experience: Scrolling through a lot of information on a single page can be less user-friendly than having it organized across multiple pages.

So, while one-page websites can be successful, it’s worth considering their limitations and whether they suit your needs. If your goal is to target a wide range of keywords, build strong backlinks, or provide a more user-friendly experience, a multi-page website might be a better choice.
