Hi, @Pooja7 !
Katy here from Shopify. I hope all is well with you!
Great question! Adding blog articles to your store is a great way to allow you tell stories that convert visitors into customers. As well as helping to boost your SEO they also increase customer engagement with your brand.
At the moment, blog posts can be linked to areas such as your: homepage, navigation and footer. By default it is not be possible to link anything other than products through to your collections. However there are some options which you may like to consider:
It is possible to add tags to your products and collections, but these would not automatically sync with one another. We have some info on this here. Anything beyond this would require custom coding or the help of a Shopify Expert. However, I do hope that the above apps offer you a suitable workaround - each comes with a free trial to help test out this feature.
