Google Ads can show you the words customers use before they enquire or buy. Those words are useful starting points for TikTok Search Ads. The campaign results attached to them are not portable: matching, creative, audience context and conversion measurement still need a fresh test.
The practical choice is what to reuse, what to rewrite and what to verify. This guide follows TikTok’s August 2026 Search Ads setup documentation and February 2026 negative-keyword guidance, reviewed September 14. It provides a migration method rather than a forecast of cheaper conversions.
- 01Transfer the customer question.Retain the problem behind a successful query; reconsider the ad and landing-page answer.
- 02Rebuild exclusion logic.Do not assume positive and negative keyword labels have identical semantics.
- 03Judge accepted outcomes.Use qualified enquiries or completed orders, not a cross-platform comparison of clicks alone.
- 04Record the configuration you actually used.A feature described in a global help page does not establish every account’s eligibility; the record says what was live when the test ran.
01 — Practical guidanceSeparate the keyword from the query
A keyword is a targeting instruction. A query is what somebody searched. Google’s matching documentation says positive exact match can include searches with the same meaning or intent. A successful exact-match keyword therefore does not prove that one literal phrase generated every conversion.
Start with the available search-term evidence and customer outcomes. Identify the problem being expressed, whether it concerns a brand, a comparison or an immediate purchase, and which destination answered it. Exclude irrelevant terms before proposing a new channel test.
A phrase such as “waterproof backpack” might represent product discovery, a durability question or shopping for a specific size. That illustrative phrase is not evidence of search demand on either platform. Write the intended question beside the phrase so the creative team has more than a spreadsheet of words.
02 — DefinitionWhat transfers and what needs rebuilding
TikTok’s Search Ads setup guide places keywords at ad-group level and limits these ad groups to search results. It supports multiple creative formats. This is a defined campaign context; do not treat every TikTok ad appearing near discovery content as the same product.
The following table is a proposed migration record. Retain the business insight in the second column and verify the implementation in the third. A missing platform option should stay marked unavailable, rather than being filled with an apparently similar control.
| Input from Google Ads | Reusable insight | TikTok work before launch |
|---|---|---|
| Converting search terms | Customer problem and useful language | Check relevant query opportunities and matching. |
| Negative keywords | Known reasons a visitor is unsuitable | Verify match type and add necessary wording variants. |
| Ad promise | Offer and factual benefit | Create an answer suited to the selected creative format. |
| Landing page | Product facts and conversion path | Check message continuity and mobile completion. |
| Cost per qualified outcome | Business acceptance criterion | Measure a fresh result with consistent definitions. |
03 — The evidenceCheck negative keywords separately
TikTok’s negative-keyword guidance documents broad, phrase and exact exclusions. Broad blocks searches containing all excluded words in any order; phrase requires the specified sequence; exact requires the whole query. Singulars, plurals, misspellings and synonyms need separate consideration. Capitalisation is the stated exception.
For an illustrative exact negative [used backpack], a different plural or an additional word may remain eligible under the documented rule. That can matter when excluding second-hand enquiries, jobs or services you do not provide. Review the actual search terms available after launch rather than assuming a pasted negative list is complete.
Keep a short reason for each exclusion. An aggressive list can block useful discovery as well as waste. If an AI assistant suggests additions, require it to explain the business mismatch and match behaviour. The reviewer should be able to reject a suggestion without reconstructing the original campaign history.
04 — MethodTest whether the creative answers the search
Build a small set around a coherent customer problem. A product demonstration can answer a practical question; a comparison can explain a trade-off; a service ad can clarify eligibility and next steps. Keep the claim verifiable and make the destination deliver what the ad promises.
A literal copy of a Google text ad is not an adequate creative brief. Identify what the viewer needs to see, what must be said and which evidence supports the claim. When using video, compare the underlying outcome rather than treating differently defined views as equivalent. Our video-view reference documents that issue.
Before spending, verify availability in the relevant account and market, tracking consent, destination behaviour and the event selected for optimisation. Record the campaign configuration actually used. A feature described in a global help page does not establish every account’s eligibility.
05 — The costDecide whether the new channel earns more budget
Use the same business definition of a qualified outcome across channels, while preserving each platform’s attribution settings. Reconcile leads to the sales process or orders to fulfilment. A lower reported cost is less persuasive if the new channel produces more duplicates, unsuitable enquiries or cancellations.
Set a review point and a decision rule before inspecting early results. A sparse test may tell you which messages deserve more investigation without proving a channel winner. Record uncertainty and the creative learning alongside the cost figures. The incrementality distinction remains relevant even when both platforms report conversions.
For paid-media planning, the useful outcome is a justified next step: expand a working problem-and-message combination, repair a broken conversion path or stop a poor fit. None requires declaring that TikTok has replaced Google Search.
For the wider discovery context, see search everywhere optimisation. Use it to frame customer journeys, while retaining separate evidence for each campaign.

06 — The failuresFour transfers that moved the wrong thing
The guide separates what transfers from what must be rebuilt because the common mistake is to carry something across that only looks portable. The illustrative transfers below each move the wrong thing. They are patterns the migration table anticipates, not accounts we have run.
The pasted negative list
A Google negative list is uploaded unchanged. TikTok’s exact negative requires the whole query, so under the documented rule an exact negative for a used backpack may leave a plural or an additional word eligible, and second-hand enquiries the list was meant to exclude can still arrive.
The text ad as the brief
The Google headlines and descriptions are handed to the video team as the creative brief. The viewer needed to see something; the brief said what to type. The ad does not answer the search it appears beside.
The cheaper click as the verdict
TikTok reports a lower cost per click and the channel is declared the winner. Reconciled to the sales process, the new leads include more duplicates and unsuitable enquiries, and the business outcome was never compared on a consistent definition.
The keyword as demand
A converting Google exact-match keyword is treated as proof that the same phrase is searched on TikTok. Google’s exact match can include searches with the same meaning or intent, so even on Google the literal phrase did not generate every conversion.
Each case carried a result across and left the insight behind, which is the reverse of what the table asks. The record in the next section keeps the two apart for every keyword group.
07 — The recordA migration record per keyword group
The table calls itself a proposed migration record, and the record is written once per group of keywords that share a customer question. The question itself, in a sentence, with the problem, whether it concerns a brand, a comparison or an immediate purchase, and the destination that answered it on Google. The Google evidence: the converting search terms and the outcomes behind them, reconciled to leads or orders rather than clicks. The TikTok rebuild: the keywords at ad-group level in a search-results ad group, the negatives rewritten per TikTok’s broad, phrase and exact definitions with singulars, plurals, misspellings and synonyms considered, and a reason beside each exclusion. The creative brief: what the viewer needs to see, what must be said and the evidence behind the claim, with the destination delivering what the ad promises. The configuration actually used: availability in the account and market, tracking consent, the event selected for optimisation and the destination behaviour, recorded on the launch date.
An illustrative record for a durability question around a waterproof backpack reads: question, whether the bag survives daily commuting in rain; Google evidence, the terms that converted and the orders behind them; rebuild, a search ad group with the relevant phrases, an exact negative for second-hand enquiries plus its plural and common misspellings, each with its reason; brief, a demonstration of the bag in rain with the warranty stated, landing on the product page that answers the question; configuration, the account’s search ads availability confirmed, consent in place, purchase as the optimisation event, launched on a stated date.
The record also carries the decision rule and review point the budget section asks to be set before early results are inspected, so the verdict is read against a rule written down in advance rather than against the most flattering column on the day.
The customer question and the reasons an enquiry was valuable move between platforms. The matching behaviour, the creative, the attribution and the conversion evidence are rebuilt on the new one, and the record says which half each entry belongs to.
08 — Next stepKeywords transfer; results do not
Write the record for one keyword group before the first TikTok campaign is built. The hardest field is the customer question, and Google’s search-term evidence is enough to start it.
Move the insight, then earn the result
Reuse customer language and the reasons certain enquiries are valuable. Rebuild matching, creative and measurement for the actual TikTok campaign. Increase investment only when its own evidence supports the business outcome you need.
