Is it bad for SEO to share an entire blog post to your own website?

When another website links back to yours, this is called a 'backlink'. Backlinks are great for SEO as it shows your customers and search engines that your site can be trusted, is reliable and should be put higher up on search engines. In this case, if it is a well-known blogger that is linking back to you, this further emphasises that your site is trustworthy as the blogger's site will already have that good reputation.

If you include the blog post on your site, it will give your customers that 'vote of confidence' to trust your site, and provides valuable-for-SEO' links. Linking to other bloggers allows you to draw people in for discussion, and outbound links to sites that have authority help to boost your SEO.

Posting content that's already been published somewhere else is considered plagiarism. And the algorithms don't like websites containing plagiarized content. Hence, I'd recommend you share 30-70 word quotes/snippets only along with a direct link to the original article - with the blogger's permission. If customers find the reviews good, they'll return and purchase for sure.

It wouldn't be a good idea to share an entire blog post of another site on your own, making it duplicate content. Search Engine doesn't like duplicate content and hence, it could affect the ranking of your site negatively. You can ask the blogger to link your site in the product review because a backlink can benefit your site. Or , it would be better to put the article as an outbound link on your website.
