The short answer
If you want sales on your website, use Ads Manager. If you want more people to see and react to a post, a boost is fine. Meta calls a boosted post the simplest way to help a post reach more people. It is still an ad, and it shows up on your bill as one. But boosted posts have fewer customisation and targeting options than an ad built in Ads Manager. For a store that needs orders, the missing options are the ones that matter most. Think of a boost as a loudspeaker for one post, and Ads Manager as a tool for finding buyers.
What a boost lets you set
Boosting is quick, and that is its main appeal. A boost starts from a post, Story or Reel you have already published. You pick a goal, such as more messages, more engagement or more website visitors. Then you choose an audience, a duration, a daily budget and where the ad appears. Meta can also try other text versions it thinks will do better. One tip if you boost from an iPhone. Meta says an Apple service fee of 30% may apply when you boost in the Facebook iOS app. Use a desktop browser instead.
Boost and Ads Manager side by side
| Point | Boosted post | Ads Manager |
|---|---|---|
| Starts from | A post you already published | A new ad built for your goal |
| Goals | Website clicks, Page engagement, local promotion | Sales, leads, app promotion and more |
| Targeting | Interests, age and gender | Adds custom and Lookalike Audiences |
| Placements | Facebook Feed, plus Instagram if you tick it | Also Stories, Messenger, WhatsApp status and more |
| Formats | The post as it is | Carousel ads and your own descriptions |
| Budget and reports | A budget and a duration | Full campaign, budget and performance tools |
Why sales need Ads Manager
The big gap is what the ad optimises for. Meta says a boosted post may at first optimise for likes, comments, shares or awareness. An ad from Ads Manager can optimise for website conversions and shop orders. With the Sales objective and your pixel in place, Meta looks for people likely to buy, not people likely to tap like. Ads Manager also lets you reach past visitors with custom audiences, and new buyers with Lookalike Audiences. Those tools live in Ads Manager, not behind the Boost button. It takes longer to set up, but you control each choice, from the objective down to the placement.
When a boost is the right call
A boost still has its place. Meta itself says boosting is a great way to build engagement and brand awareness. Use it when a Reel is already doing well and you want more people to see it. Use it for a launch post, a festive greeting or a post that asks people to message you. It is also a cheap way to test which idea people like before you turn it into a proper sales ad. Keep the budget small, and stop the boost when the post stops getting reactions. Just do not judge a boost by the sales it was never built to make.
A simple plan for a small store
Keep both, but give each one a job. Put most of your ad money into one Sales campaign in Ads Manager, aimed at your best products. Use small boosts on posts that already work, to grow reach and followers. Judge each against its own goal: orders for Ads Manager, and reach or messages for boosts. Review both each week. Every click from either one lands on your store, so your pages must sell. On The Storemate you can build those pages with the page builder, and take UPI, cards and COD at checkout.
