Alright, a few suggestions here.
I wouldn't just up the budget on the current ad set. Doubling it is a big change and will almost definitely reset the learning phase, so your results will get unstable for a bit.
The 'learning' status just means Facebook is still figuring out who to show your ad to. You need about 50 sales per week for an ad set to get out of learning, which is tough on $25 a day, so don't worry about it too much. It's normal at that spend level.
The bigger issue, I'd say, is your targeting. 'Jewelry' is a massive interest, covering millions and millions of people. You got a bit lucky with 6 sales, which is great, but to spend $50 a day well, you need to get way more specific. For the eCommerce stores we run ads for, getting the audience right is everything. I remember one campaign we worked on for a women's apparel brand; a big part of achieving a 691% return was moving away from broad targeting and really drilling down into specific style interests and competitor brands.
Think about who buys your specific items. What's their style?
-> Do they like handcrafted things? Try targeting people interested in 'Etsy' or 'handmade jewelry'.
-> Are they into certain brands? Try targeting competitor brand names.
-> What magazines would they read? Try interests like 'Vogue' or more niche ones.
What I'd do is create a new campaign. Use the 'Campaign Budget Optimisation' setting and set the new budget to $50. Then, inside that, create 2-3 different ad sets with separate, more specific audiences. Let them run for a few days and see which one does best, then turn off the losers. You're just giving Facebook better options to find your buyers.
Hope this helps!
I wouldn't just double the budget on that ad. It'll likely reset the learning phase, and you'll be spending more money on a really broad audience.
The main problem is the 'Jewelry' interest is way too general. You need to be more specific to get consistent results. I'd start a new campaign and test 2-3 much more specific audiences, like people interested in 'Etsy' or fans of a specific competitor brand. Find the winners first, then think about scaling.
Hope that helps!
A couple of thoughts here. First off, congrats on the 6 sales on that budget; that's a good start.
Regarding your question, I'd avoid just doubling the budget on the live ad set. It's a big enough change that it will likely knock it back into learning and make performance unstable. A better way to test a higher budget is to duplicate the ad set and change the budget on the new one.
However, the bigger issue here is your targeting. 'Jewelry' as an interest is incredibly broad. For every one person in that audience who might buy your jewelry, there are thousands who won't. To make $50/day work properly, you need to give Facebook a much better idea of who your customer actually is. I've seen this with many eCommerce clients; for instance, we helped a women's apparel store achieve a 691% return on ad spend, and a key part of that was getting very specific with audience targeting, moving beyond general interests.
Try testing some more focused interests in separate ad sets. Think about what makes your products unique. Is it for weddings? Target people with an 'Engaged' life event. Is it a certain style? Target interests related to that style (e.g., 'bohemian style') or magazines that cover it. This will give you much more reliable data.
Hope this helps!
