The user chooses the move; Snifferdog™ makes both changes and checks they landed. Try moving money out of TikTok to see the minimum spend rule.

Decisions so far

  • Campaigns tab: option A. The demo's existing card, plus a pause/play switch, a timeline showing days left, and a Live edit mode button. Nothing else on the card.
  • Live edit mode: a copy of the demo editor with a live banner, a toolbar for the common jobs (budget, dates, pause, this campaign's analytics) and a tray of pending changes. No CMS needed.
  • Review: nothing reaches a platform until the user publishes. Every warning links to the Help Centre.
  • Move budget: user-initiated only, with each platform's minimum enforced and explained.
  • Copy: Snifferdog™ is the AI and does any analysis or flagging. Tove is a guide only and never analyses, recommends or acts. Write “Snifferdog™ will flag it”, never “Tove will flag it”.

Ground rules for the build

  • Changes are held in Snifferdog™ until the user publishes, then sent in one batch per platform to stay inside rate limits.
  • Read minimum budgets from each platform rather than hard-coding them. They vary by currency, bid strategy and account, and they change.
  • Money already spent today can't be undone. A lower budget only limits what's left of the day.
  • Every change, including pause and resume, is written to Change history with who made it, when, and whether the platform confirmed it.
  • Anything that resets a campaign's learning gets an amber warning and a link to The learning phase explained.

Moving budget between platforms

TikTok minimum spend: £50 a day per campaign

TikTok won't accept a campaign daily budget under its minimum. If a move left TikTok on £49 a day, TikTok would reject it and that £49 would sit there unspent. So a move out of TikTok can only take it down to £50, or the user moves all of it and TikTok is paused. Both options are explained on the screen. TikTok's help quotes $50; we're using £50 until devs confirm the figure in a GBP account.

  • Order: lower the first platform, check it landed, raise the second, check that landed. If either fails, put both back and tell the user. Two separate API calls, never assumed to succeed together.
  • Minimums: TikTok £50 per campaign (and £20 per ad group). Meta's minimum depends on the bid strategy and what's being paid for, and takes spend so far into account, so read it from Meta. Google has no fixed published minimum; we use £1 as a floor. Microsoft £0.05.
  • Gentle limits: amber warning above 20% of the source budget. For TikTok, warn above a 30% rise and check the last change was at least two days ago.
  • Exclusions: paused campaigns aren't offered, and moves are discouraged while either side is learning or in its first or last three days.
  • Money: each ad account is billed separately, so a move changes spending rates, not money between accounts. Check the receiving account's balance or spending limit first, especially prepaid TikTok accounts.
  • Comparisons: platforms count conversions differently, so the screen never ranks them on raw cost per lead.

Help Centre

Open questions for the devs

  • TikTok's minimums in a GBP account: is it £50 and £20, or a converted figure?
  • Every TO CONFIRM cell in the table above.
  • Rate limits per platform, and how changes are batched and retried.
  • How undo works when the platform has already spent against the new budget.
  • Where Change history lives, given ad data isn't stored: our own log, the platforms' change history APIs, or both.

One level down the structure tree in live edit mode: every ad set and ad gets its own switch, and selecting an ad opens it on the right. Same pending-changes tray and review step as everything else. Try pausing all the ads in the Retargeting ad set.

The last running ad in an ad set can't be paused on its own; pause the ad set instead.

Ad 3 is tiring. Its click-through rate has dropped by 38% over 7 days while the same people keep seeing it. Snifferdog™ suggests swapping in a new image. Swap Ad 3

On Meta and TikTok, changing the text, image or landing page creates a new version of the ad behind the scenes. It goes back for review and its results start again. To protect an ad that's working, add a new version alongside it instead.

Ad sets and ads (screen 6)

  • Pausing at every level (API-04): every platform has a status on ad sets, ad groups and ads, so this extends the existing campaign-level pause. Snifferdog™ blocks pausing the last running ad in an ad set, and the last running keyword in an ad group, because either stops delivery without the user realising.
  • Add, swap and pause ads (API-25): adding means uploading from the Library and creating the ad in the existing ad set. Swapping means adding the new ad, then pausing the old one once the new one is approved, so there's no gap.
  • Landing pages and copy (API-23, 25): on Meta and TikTok any change creates a new creative behind the scenes; on Google the final URL can be changed on the ad. Either way the ad is reviewed again.
  • Protecting what works (API-40, 43): the default is “add a new version alongside”, not edit. We say “with minimal disruption”, never “won't reset learning”.
  • Fatigue nudges (API-28): flagged by Snifferdog™ when click-through falls while frequency rises. Most useful on TikTok, where ads tire fastest. Thresholds to agree with the devs.
  • Meta placements (API-27): default to Meta choosing (Advantage+ placements); manual placements are optional and restart learning.
  • Naming: the tree uses each platform's own word (ad set on Meta, ad group on TikTok, Google and Microsoft, asset group on Performance Max).
