LiveVerteco Product Lab
Before/after title tests per product, with the stats to prove it.
Product Lab tests a new title on up to 200 chosen products: starting the experiment publishes the variant-B titles through the hosted supplemental feed and snapshots each product’s impressions, clicks, cost and conversions from your latest Google Ads report as the baseline. When you upload a report covering the days after the start, the tool compares before and after per product and in aggregate, runs a two-proportion z-test on CTR and gives a verdict; stop restores the previous titles, adopt keeps variant B live. Google serves one title per product at a time, so this is a sequential before/after comparison rather than a simultaneous split, and image variants are out of scope.
A better product title should mean more clicks, but without a controlled comparison nobody knows whether it did. Product Lab is a title testing tool for merchants who want to change titles on chosen products and read the before/after result with a statistical test.

What Product Lab reads today
Product Lab reads the daily feed snapshot for the products you pick, the Feed Tuner title suggestions when they exist, and your uploaded Google Ads product reports for the metrics. An experiment is a draft until it starts: you search and select up to 200 products, give each a variant-B title, prefilled from an unapproved Feed Tuner suggestion where there is one, and set a planned duration of 7, 14, 21 or 28 days. At start, the tool snapshots each product's impressions, clicks, cost and conversions from the latest uploaded report as the baseline. Up to 20 experiments are kept per shop. Nothing is fetched from Google Ads; results arrive when you upload a report covering the days after the start.
How a title test works, step by step
Starting the experiment publishes the variant-B titles as approved title overrides through the supplemental feed Komplet hosts, so Google serves them after its next fetch. Titles are written in bulk and committed together with the experiment state, so an interrupted request cannot leave titles published for a draft. After the planned period you upload a new Google Ads product report. Product Lab compares the baseline with the newest report uploaded after the start, per product and in aggregate: CTR, CPC and conversions, the lift, a two-proportion z-test on CTR and a verdict. Stop restores the previous title or override and freezes the result; adopt keeps variant B live and freezes the result too.
What it changes in Merchant Center or Google Ads
Product Lab changes titles only, and only through the hosted supplemental feed you added in Merchant Center; your primary feed is never modified and nothing is written to Google Ads. Google serves one title per product at a time, so this is a sequential before/after comparison, not a simultaneous split, and seasonality or bid changes during the period affect the reading; the tool says so. Image variants are out of scope because the supplemental feed publishes titles and custom labels only. An adopted variant stays live as an override, visible in Feed Tuner, until you remove it.
Frequently asked questions
Is Product Lab included in the €19 subscription?
Yes. Product Lab is part of Verteco Komplet and included in the verteco.shop CSS subscription of €19 per month or €199 per year per shop, together with the hosted supplemental feed that publishes the test titles. There is no per-experiment or per-product charge.
Does Product Lab change my feed?
Not your primary feed. Variant-B titles go out as title overrides through a separate supplemental feed hosted by Komplet, matched to your products by id. Stopping the experiment restores what was there before; adopting keeps the new title live until you remove the override in Feed Tuner.
Is this a real A/B test?
It is a before/after test per product. Google serves one title per product at a time, so two titles cannot run simultaneously for the same item. Product Lab compares the baseline period with the period after the start, runs a two-proportion z-test on CTR and states this limitation in the verdict.
How do I get the results into Product Lab?
Export the Google Ads product report for a date range after the experiment started, one row per Item ID with impressions, clicks, cost and conversions, and upload it. Product Lab uses the newest report uploaded after the start. A Google connection that reads the report automatically is planned, not available yet.
How many products and experiments can I test?
Up to 200 products per experiment and up to 20 experiments per shop, with a planned duration of 7, 14, 21 or 28 days. Fewer products with enough clicks each give a clearer verdict than many products with a handful of clicks.
