Can we submit our blog post in article submission sites?

Yes, You can submit your blog post on the article submission site.
But As recommended do not submit, it is not an good thing.

Ideally, you shouldn't post the same content across multiple sites to avoid Duplicate Content Penalties From Search Engines, and also it will not pass on any value to your original blog article if you post it on multiple sites.

You need to publish content only on sites that are willing to use a rel=canonical.
Most big sites such as Medium or LinkedIn don't give you full control.

Content syndication is possible, but only strategically. Publish the original first, then syndicate selectively to reputable platforms that support canonical tags or clearly credit the source. Otherwise, you risk dilution and little SEO value.

"Yes, article submission sites can help with visibility, but the quality and relevance of the site matter. It's better to focus on reputable platforms rather than submitting the same article everywhere."
