Google Ads vs Facebook Ads: choose a channel with a decision worksheet

Define which Google campaign you are comparing

Google Ads is a platform, not a single kind of advertisement. Search, video, display and cross-channel campaigns do not reach people in identical situations. The comparison below focuses on Google Search ads and Meta feed advertising. A claim such as “Google captures intent and Facebook creates it” can be a useful starting question, but it is too broad to describe every campaign on either platform.

Write down one offer, one audience and one meaningful outcome. For a software product, that might be a completed trial signup from a business that matches your intended customer. For a service business, it might be an enquiry that passes a qualification check. Use the same definition when you review both channels. A newsletter subscriber and a paying customer belong in different columns.

Use this comparison before choosing a budget

The table is a planning aid, not a prediction of which channel will produce the cheapest customer. Fill the evidence gaps before committing to a larger test.

When Search is a sensible first experiment

Start by finding searches that describe the problem your offer actually solves. Read the results and ask whether the searcher wants a product, a tutorial, a free resource or a different service entirely. An apparently relevant phrase can hide the wrong intent. A campaign for a paid scheduling tool should not assume every search for a printable calendar expresses buying intent.

Build the destination around the promised task. If the ad offers a team scheduling workflow, show that workflow, its requirements and the next step. Sending every query to a broad homepage can make it difficult to understand what went wrong. Review search terms after the campaign runs and prepare exclusions for clearly irrelevant intent; do not remove all research queries simply because they did not convert immediately.

When Meta is a sensible first experiment

Meta can be worth testing when the product is easier to understand through a concrete demonstration than through a category name. Show the customer situation, the product action and the visible result. A short demonstration of finding a saved item is more specific than a generic promise to save hours every week. Use evidence you can show and avoid claims that the product experience cannot support.

Plan more than a cosmetic variation. Two ads with different background colours may test presentation, but they do not tell you whether the audience responds to convenience, clarity or a particular use case. Record the hypothesis for each creative. If you change the audience, offer, destination and creative together, the result may be useful operationally but it cannot isolate which change mattered.

Copy this first-campaign worksheet

Complete one row per proposed campaign. Keep unknowns visible. The worksheet is ready for a spreadsheet or a project note; it does not require connecting an advertising account. Decide who can approve spending and who will review the result before launch.

Compare business outcomes without adding duplicate credit

Illustrative example: Google reports five purchases and Meta reports eight, while the store records ten distinct orders for the period. The advertising reports do not establish thirteen unique purchases. Both platforms can assign credit along overlapping customer journeys, using their own attribution settings. Keep the provider totals intact and reconcile the order count separately.

Write down the reporting timezone, currency, date basis, conversion action and attribution setting beside each result. Check whether refunds, repeat purchases or duplicate events affect the business total. Do not silently replace a missing provider field with zero. If the reports cannot be made comparable, describe the difference and narrow the question rather than producing a single blended figure that implies false precision.

Platform cost per conversion can help compare campaigns using the same definition. It cannot, on its own, establish the cost of an additional customer caused by advertising. A causal question needs a suitable experiment and enough evidence. For an initial operational review, focus on qualified outcomes and whether the offer reached the intended people.

Choose the next action from the failure you can observe

If relevant Search clicks reach the page but the form fails, fix the form before replacing the channel. If a Meta ad attracts attention but introduces an offer the destination never explains, repair the message and page alignment. If signups arrive but are consistently outside your target audience, review qualification and targeting evidence. These are different problems even when all three campaigns show a disappointing cost per signup.

Keep a short change log with the previous setting, the proposed change, the reason and a review date. Avoid changing every variable after a small fluctuation. Equally, a clearly broken destination does not need weeks of additional spend to become actionable. Separate technical defects from uncertain performance explanations.

Use Adlane to keep the review tied to the right account

Adlane supports Google and Meta advertising conversations with connected account evidence and reviewable proposals. Start with a bounded request: “Compare the last two complete periods for this account, keep the conversion definitions separate, and identify what we need to check before changing budget.” Available evidence depends on the account permissions and provider fields.

Review the current setting and proposed action before approving a change. Adlane does not turn unlike attribution totals into deduplicated customers, and it does not guarantee better returns. Use the worksheet to decide which question matters, then use the connected evidence to prepare a specific next step. Adlane is independent of Google and Meta.
