Now Facebook doesn’t promise to show your post to these people but it will take your preferences into consideration in the news feed algorithm so that people matching your criteria are more likely to see your post in their news feed.
They can also target posts to people who are based near local stockists. Not only are there French speaking regions in Canada but they might want to go one step further to make the most of regional differences in the UK - like whether you are using cooking spices for tea or dinner (but let’s not argue about that here). They can tailor their language not just to each country but also to different regions. They can use the audience preference setting to optimise the reach for posts with prices in pounds for the UK and dollar pricing in Canada. This is really useful for one of my clients, a spice company in Canada who also operate in the UK. You can select a minimum and maximum age range, gender, locations to include or exclude and up to 16 interests. The options you will see are similar to those available when boosting a post. When you have the audience post optimisation settings activated you will be able to choose who you would prefer to see your posts based on their interests and demographic criteria.
Yes you read that correctly, you can now select audience preferences for your posts - not just for paid ads.
