While Google Sites can provide backlinks, their SEO benefit is generally considered to be low. Google Sites links are often nofollow, meaning they don't pass link equity or influence your search rankings directly. However, there might be some indirect benefits:
Increased Visibility and Traffic: If your Google Site ranks well for relevant keywords, it can drive some traffic to your main website, even if the link is nofollow.
Brand Awareness: A well-made Google Site can help increase brand awareness and provide additional information about your business or organization.
Potential for Indexing: Google Sites are generally indexed quickly by Google, which could help with the overall indexing of your website if you link to it from your Google Site.
Overall, while a link from a Google Site might not be a game-changer for your SEO, it can still offer some minor benefits, especially for local businesses or organizations looking to expand their online presence.
However, it's important to focus on acquiring high-quality backlinks from authoritative and relevant websites in your niche, as these will have a much greater impact on your search rankings.
