I tried pinning a blog post to the top so that it appears before all other blog posts (not Pinterest) on Shopify Blogs, but I couldn't find or figure out an option to do that. I don't necessarily want to pay $10/m for an app if I just want to pin 1 blog post at a time. I use Debutify as a theme - any suggestions?
In order to accomplish this you would need to make some changes to your themes code. If you are not interested in paying for a monthly app, I would suggest looking to hire a developer who can code in this functionality onto your store. We have a Shopify experts directory where you can find and hire a suitable expert for the job.
Otherwise, as a free workaround - most blogs are set to display by date of creation - what you could do here is reset the publish date (by hiding it and making it visible again) of the blog you want to remain at the top. You can do this whenever a new blog post has been created so that it stays at the top.
If there is anything else I can help you with, please let me know.
