What does this mean?
Thin content is content that has little or no value to the user. Google considers doorway pages, low-quality affiliate pages, or simply pages with very little or no content as thin content pages.
But don’t fall into the trap of just producing loads of very similar content: non-original pages, pages with scraped and duplicate content, are considered thin content pages too.
On top of that, Google doesn’t like pages that are stuffed with keywords either and can now distinguish between valuable and low-quality content.
What to do?
Solve this by producing high-quality, relevant, and original content.
