exceeding the recommended limits is not advised as it may impact the user experience tracking and conversion provide tracking urls to measure campaign performance and process payouts standard tracking (single conversion) use this format for offers with one conversion event and a fixed payout https //track adspostx com/track/?click id={click id} event based tracking (multiple conversions) use this format for offers with multiple conversion events or variable payouts https //track adspostx com/track/?click id={click id}\&measurement=1\&event={event id}\&payout={payout} additional parameters you can pass additional data using custom 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 actual values or macros supported by your tracking platform writing guidelines strong copy communicates offer value in seconds users decide whether to engage based on what they immediately understand, so clarity beats creativity every time 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 understanding the difference between short and long descriptions is crucial for effective communication of your offer if short and long read the same, they’re wrong short description purpose quickly convey the main benefit of the offer for mobile users character limit aim for 60–90 characters content focus on a single, compelling benefit without including the brand name example save up to 30% on your next rental long description purpose provide additional context and reassurance about the offer for desktop users character limit target 100–130 characters content expand on the short description, explaining how the offer works without introducing new ideas 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") examples 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) examples 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 language poor visit our website to learn more about this offer not benefit focused, vague cta brand name usage your logo is your visual signature, it tells users who you are instantly so mentioning your brand name in copy usually just wastes space you could use to highlight what users actually care about what they get the general rule is simple skip the brand name in your copy why this works your logo handles the heavy lifting for brand recognition your copy should focus on answering the user's real question "what's in it for me?" not "who am i buying from?", they can see that from your logo with mobile screens cramped for space, every character counts spend it on the benefit, not the brand name when to break the rule brand names belong in copy only in specific situations luxury or prestige brands where the name itself signals quality ("access exclusive hermès collections") potential confusion if your logo doesn't clearly communicate who you are legal requirements that mandate brand disclosure in the offer text multiple brands in one offer where clarity prevents confusion self check test read your copy without the brand name ask does the offer still make complete sense? if yes → keep it removed if no → consider if logo solves the ambiguity before adding brand name call to action guidelines the cta button drives user engagement effective ctas are specific, action oriented, and communicate clear value we may suggest alternative ctas based on your offer type and our performance data cta optimization can improve click through rates recommended ctas unlock deal view offer get discount see
