momentscience serve the best fit by placement copy specifications use these ranges to ensure proper display and strong performance across placements field minimum target maximum header/title 30 45 characters 50 characters short description 40 characters 60 90 characters 140 characters long description 80 characters 100 130 characters 180 characters cta (yes) 2 3 words 4 words aim for the target range copy that's too short may lack impact, while copy exceeding the maximum will be truncated customization options dynamic macros add dynamic fields passed to momentscience so copy can adapt to

u1m7w0zxfxch7tzk6 gfj description options offer descriptions can include text descriptions bullet lists icons the short description and long description fields support html formatting, allowing you to style content with bullet points, emoji icons, and custom list styling character limits for bullet points long description up to 30 characters per line, up to 4 lines short description up to 30 characters per line, up to 3 lines standard bullet points free shipping on all orders no promo code needed limited time offer emoji icons as bullets 🚚 free shipping on all orders ✅ no promo code needed ⏳ limited time offer the sdk can render beyond these recommendations (up to 5 lines on desktop and 4 lines on mobile), but going beyond recommended limits usually degrades readability tracking and conversion provide tracking urls to measure performance and process payouts standard tracking (single conversion) use this format for offers with one conversion event and fixed payout https //track adspostx com/track/?click id={click id} event based tracking (multiple conversions) use this format for offers with multiple events or variable payouts https //track adspostx com/track/?click id={click id}\&measurement=1\&event={event id}\&payout={payout} additional parameters sale amount sale amount for cost per sale (cps) goal tracking use this parameter alongside payout when tracking the actual sale value for cps calculations for example sale amount=149 99 event event type identifier required for variable payout tracking common values include purchase , signup , lead , or custom event names for example event=purchase payout payout amount for the conversion in usd specify the dollar amount (e g , 25 50 ), not cents for example payout=25 50 additional custom parameters as needed for campaign specific tracking requirements replace {click id} , {event id} , and {payout} with values or macros from your tracking platform use click id with an underscore click id (hyphen) does not work and can cause silent attribution failure writing guidelines strong copy communicates offer value quickly users decide whether to engage based on what they understand immediately your creative's text does three jobs it captures attention, explains value, and motivates action poor copy can undermine excellent design, users won't engage with offers they don't quickly understand short vs long description if short and long descriptions read the same, they are ineffective short description purpose quickly convey the primary benefit for mobile users character limit 60 90 characters content one clear benefit, no redundant brand naming example save up to 30% on your next rental long description purpose add context and reassurance for desktop and expanded placements character limit 100 130 characters content expand the short description without introducing a different offer example save up to 30% on your next rental discount applies automatically at checkout header best practices headers are crucial in capturing user attention and setting expectations for your offer they play a significant role in user engagement best practices clearly state one specific idea focus on outcomes and benefits rather than features use action oriented language keep headers concise and easy to scan avoid jargon and ambiguous terms common mistakes to avoid using compound phrases that dilute the message stating category names instead of benefits (e g , "apparel sale" vs "save 40% on apparel") redundant brand names, as the logo already provides branding exceeding 50 characters, which may lead to truncation on mobile making vague promises (e g , "amazing deals" vs "save 30% today") quality example why good save 30% on your next order clear benefit, specific discount good get 4 bottles of wine for $24 95 specific offer, clear value good free shipping on orders over $50 actionable, benefit focused poor brand name category savings generic, no specific value poor amazing wine deals vague, no concrete benefit poor check out our latest apparel collection today too long, not benefit focused description best practices descriptions work with the header to provide complete offer information they answer the question "what's in it for me?" best practices expand on the header with concrete details explain how the offer works (auto applied, code needed, etc ) include relevant product details or limitations address common questions or concerns use clear, conversational language focus on user outcomes, not brand features common mistakes to avoid repeating the header word for word including brand name when logo is present using bulleted lists or excessive punctuation generic filler language ("great deals," "amazing quality") introducing new concepts not mentioned in short description (long only) quality example why good get premium wines delivered with automatic savings at checkout explains process, adds value good enjoy curated selections with free shipping on orders over $50 specific details, clear benefit poor save 30% on your next order from acme wines today redundant brand name, no new info poor amazing quality products at great prices vague, generic poor visit our website to learn more about this offer not benefit focused brand name usage general rule do not repeat the brand name in copy when the logo already establishes identity use brand names in copy only when the brand itself is a value signal the logo is unclear legal language requires disclosure multiple brands need disambiguation call to action guidelines recommended ctas unlock deal view
