LiveVerteco Verdict
Run the test. Read the verdict.
Verdict has four parts: a savings calculator from your monthly Shopping spend and average CPC, with break-even against the €19/month CSS fee; a guide to two A/B test designs – a Google Ads experiment with a user-based split, or two Merchant Center accounts with parallel campaigns – with duration guidance and what to compare; a results form where you enter impressions, clicks, cost and optional conversions for both arms and get the CPC and CTR differences with significance tests and a verdict; and a forecast of extra clicks or savings computed from your uploaded Google Ads product report. All numbers are typed in or uploaded by you – nothing is read from Google Ads yet.
The CSS saving is a claim until it is measured in your own auctions. Verdict is for merchants who want to estimate what a CSS switch is worth, set up a fair A/B test between Google Shopping and verteco.shop, and read the result with the statistics stated.

What Verdict reads today
Verdict has four parts, and every input is typed in or uploaded by you; nothing is read from Google Ads yet. The savings calculator takes your monthly Shopping spend and average CPC. The A/B test guide needs no data. The results form takes impressions, clicks, cost and optional conversions for arm A, Google Shopping as the CSS, and arm B, verteco.shop as the CSS. The forecast reads the latest Google Ads product report you uploaded and uses its period cost and clicks. The calculator keeps your last inputs and the last 10 test results are stored per shop. The savings assumption is the one verteco.shop works with: ads placed through another CSS enter the auction without the share Google keeps for its own CSS, modelled as 20 %.
How the test and the verdict work, step by step
The calculator shows two views: same budget, more clicks, with bidding power raised by 25 %, and same clicks, lower spend, with cost reduced by 20 %, each against the €19 per month CSS fee for break-even. The guide describes two designs: a Google Ads experiment with a user-based 50/50 split, or two Merchant Center accounts with parallel campaigns, with duration guidance and what to compare. After the test you enter both arms' numbers. Verdict computes the CPC and CTR differences, runs a pooled two-proportion z-test on CTR and conversion rate and a Welch-type approximation for CPC that needs at least 30 clicks per arm, uses p < 0.05 as the threshold and writes a verdict with the assumptions.
What it changes in Google Ads
Verdict changes nothing in Google Ads or Merchant Center; you set the test up in your accounts, as the Academy article on running a CSS A/B test describes. Because a Merchant Center account has one CSS at a time, a test needs two accounts, the second as a sub-account under the verteco.shop multi-client account that the team creates for you. Verdict does the arithmetic: how big the difference is, whether it is significant, and what the forecast says for your spend. A non-significant result means the test needs more clicks, not that there is no difference. Partner Desk reuses the same formula for an aggregated estimate across an agency's clients.
Frequently asked questions
Does a CSS reduce my CPC in Google Shopping?
Ads placed through Google Shopping Europe carry a share Google keeps as the margin of its own CSS; ads placed through another CSS enter the auction without it. verteco.shop and Verdict model this as 20 %. The effect in your account depends on your auctions, which is why Verdict includes a test design and a significance test rather than a promise.
Is Verdict included in the €19 subscription?
Yes. Verdict is part of Verteco Komplet and included in the verteco.shop CSS subscription of €19 per month or €199 per year per shop. The calculator and the test guide are usable from the first day; the forecast needs an uploaded Google Ads product report.
How long should a CSS A/B test run?
At least two weeks, longer when daily clicks are low. The CPC comparison needs at least 30 clicks per arm, and 100 or more per arm gives a clearer result. Keep bids and budgets unchanged, avoid sales or feed problems in only one arm, and compare per-click metrics, not totals.
Does Verdict read my Google Ads data?
Not yet. The calculator and the results form use numbers you type in; the forecast uses the Google Ads product report you upload. There is no Google connection today, so Komplet never touches your Google Ads account. A connection that reads the report directly is planned.
What does a non-significant result mean?
That the observed difference could still be chance at the p < 0.05 threshold, usually because the arms have too few clicks. It does not mean the CSS has no effect. Extend the test, keep the setup unchanged and enter the larger numbers; Verdict stores the last 10 runs for comparison.
