Facebook disabled their search API in 2015. As a result, it is no longer possible to search for retailer pages directly. The only way a post can be shared is to share it from a pre-existing stream.
There are two ways that you can add a retailer to a stream.
ADDING A STREAM TO SHARE A RETAILER POST
You could add a stream for pages. This would allow you to see the feed of any pages you had liked. The only slight snag in this is that you would need add a stream for each retailer every time you needed to share their post. As Hootsuite have a limit on the number of streams, you’ll need to delete and readd retailers as required.
To add a retailer stream you’ll need to select ‘pages’ on the add a stream tab.
Select the Facebook page you want to add from the list. You must have liked the page as your page in order to find the retailer here.
Once you have the post you would like to share in the correct stream, you’ll need to follow these steps to share it:
Click ‘Share’ below the post.
Select the profile that will share the post from the drop-down menu.
Optional: Click Say something about this and enter a comment above the shared content.
For Facebook profiles, select the audience for the share (Public, Friends or Only Me) from the second drop-down menu, and then click Share.
Once you’re finished with the stream you can delete it.
ADDING MENTIONS TO YOUR STREAMS
If you’re working with retailers that have local Facebook pages (i.e. Starbucks Glasgow Fort) the easiest way going forward is to ask these retailers to tag your Facebook page.
You can add a stream to Hootsuite which allows you to see all your Facebook mentions. You would simply select your page below and click the @mentions logo in green. Any posts tagging your Facebook page would show up here allowing you to share content easily from one stream.
