Writing Meta ad copy: common questions
How do I write Meta ad copy that actually stops the scroll? +
The opening line is everything. Facebook and Instagram users are moving fast, so the first sentence of your primary text - and the first frame of any video - must either name a specific pain the audience feels, make a surprising claim, or ask a question they cannot ignore. Generic openings like "Introducing" or "Looking for X?" perform poorly because they signal an ad immediately. The strongest opening lines are specific: they name the audience's exact frustration, in the words the audience uses to describe it. Use voice-of-customer research (reviews, Reddit threads, DMs) to find those exact phrases - then lead with them.
How long should Meta ad primary text be? +
There is no universally correct length - it depends on your product's complexity and your audience's awareness level. Facebook and Instagram truncate primary text after approximately 125 characters with a "See more" link, so whatever comes before that cutoff must be compelling enough to earn the click. Short copy (under 125 characters) works well for simple offers with cold audiences who do not need much convincing. Long copy (200 to 500 characters) works well for considered purchases, B2B products, or audiences who need more context before converting. Test both. Many accounts find that long-copy ads outperform short-copy for high-ticket offers, while short copy wins for impulse or low-ticket purchases.
What is the most effective ad copy angle for Meta? +
The pain-first angle consistently outperforms other angles for cold traffic direct response campaigns. It works because it demonstrates empathy before asking for anything - the reader feels understood, which earns attention. Pain-first copy opens by naming the specific frustration your audience faces, agitates it briefly, then presents your product as the relief. However, the best-performing angle varies by category. In markets with social proof and clear transformations (fitness, finance, productivity), social proof angles often win because they let results do the selling. The most reliable approach is to test pain-first, aspiration, and social proof simultaneously, then scale the winner.
Should I write different ad copy for Facebook vs. Instagram? +
The angle and message can stay the same, but the format and tone often need to shift. Facebook audiences tend to be older, respond to longer copy with more detail, and are less sensitive to polished aesthetics - authenticity and specificity perform well. Instagram audiences skew younger, process information faster, and respond to visual hooks and tighter copy. On Instagram Stories and Reels, the first 3 seconds of a video or the first visible line of text is all you get. In practice, run the same core offer with the same copy in Advantage+ placements and let Meta's delivery system find who converts on which placement. Only create placement-specific variations if your data shows a major performance gap between placements.
How often should I refresh Meta ad copy? +
Watch frequency and CPM trends - not the calendar. Ad copy fatigue shows up as rising CPM, falling CTR, and declining ROAS as the same people see the same message repeatedly. For most accounts spending under $500 per day, creative fatigue appears after 2 to 4 weeks of active delivery. For larger accounts with broader audiences, a winning piece of copy can run for 2 to 3 months before performance degrades. The signal to refresh is when your frequency exceeds 3 to 4 for your target audience AND your CTR has dropped more than 25 percent from its peak. Do not change copy reactively after a single bad day - wait for a trend.
