Now you could do this with draft & experiments.

Hypothesis holds
Traffic quality gets weaker like in
broads.
Surprising: you pay more for
same traffic! Overbidding on
shopping is dangerous.

Andreas Reiffen - SMX London Slidedeck
The document discusses various methods for testing advertising strategies and optimizations, including draft and experimentation tests, scheduled A/B tests, and before/after tests. It provides examples of how each type of test could be used, such as testing landing pages with drafts and experiments, or measuring quality score changes through scheduled A/B tests. The document also outlines some common pitfalls to avoid in testing, such as not ensuring statistical significance or failing to account for factors outside the test that could influence results. Overall, the document promotes a data-driven approach to iterative testing of advertising performance.

- 6. #SMX #13B @AndreasReiffen Draft& experiments is the most diverse testing tool for almost everything Structural Tests that change the structure within a campaign • Ads • Landing Pages • MatchTypes Bidding Tests that influence bidding of some sort • Bids • Modifiers • Device • Ad schedule • Geo-Targeting • Strategies • eCPC • Target CPA Features Changes within features added to a campaign • RLSA • Ad Extensions • Sitelinks • Etc. Drafts and Experiments allow you to test almost anything within a campaign. Unfortunately this feature is currently not available for Shopping campaigns. 1

Setup: Create an Experiment, change only landing pages Analysis: Keep track of top line performance using automatic scorecard displayed in the Experiment campaign. Nonetheless, always take a deepdive into performance after finishing the experiment to rule out any irregularities
- 10. #SMX #13B @AndreasReiffen Manuallyscheduled A/B tests still have some use cases Search terms Tests where the query composition is important • MatchType changes • Negative changes Cross campaign Tests that have to be tested across different campaigns • Quality Score development in new accounts/ campaigns Shopping Any of the tests you can use D&E for inText ads • Structure • Bidding • Features What ever can‘t be achieved through D&E Use this scheduling to avoid cannibalization while still being independent from seasonality 2

- 12. #SMX #13B @AndreasReiffen Setup:Duplicate campaign & set schedule to run against original campaign. Analysis: Compare traffic & QS levels Example A/B scheduling: how fast do quality scores pick up after campaign transition? 8.3 Day 1-4 8.3 -8% 8.6 +4% 7.6 Day 5-30New Campaign Original Campaign 944 Day 5-30 -32% -3% 1,391 1,210 Day 1-4 1,252 2 Quality Scores pick up within a few days.

- 13. #SMX #13B @AndreasReiffen Before/ after are versatile and used for feed components. Control group is important. Feed changes Changes in the feed • Test new titles • Test new images Product changes Tests that affect the product portfolio itself • Price changes Things that cannot be easily changed. Make sure to have control group that indicates seasonal or budget changes. 3

- 16. #SMX #13B @AndreasReiffen GoogleMerchant Center experiments are a great idea, however lack attention from Google Google is testing feed optimisations directly in the Merchant Center interface. Tests include phase 1 and phase 2 in comparison against baseline. Not very well documented since still in beta. 4
- 17. #SMX #13B @AndreasReiffen Producttitles A vs B: Alternative values are proposed from additional column in feed. Shortcoming: products to include in test & control are randomized, not the impressions or users! Google might discontinue. Merchant Center experiments cover product titles and images to A/B test 4
- 18. #SMX #13B @AndreasReiffen OnlineA/B tools are a great help to find out whether tests have significant outcome. Trials and successes can include: clicks; conversions impressions; clicks 4

- 24. #SMX #13B @AndreasReiffen Splitvs Non-split Duplicate products, split queries in „test“, increase share of designers by higher bids. Rotate by scheduling. Test design: Rotating A/B test. Now you could do this with draft & experiments. Hypothesis holds Queries with higher conversion probability get more exposure, overcomensating higer CPCs. 80% 75% 70% 28% 35% Generics Designers 20% 100% 100% 100%Original, no split Phase 3Phase 2Phase 1 Test Control 100% Phase 3Phase 1 Phase 2 128% 137% Revenue test vs control Cost test vs control 98% Phase 3Phase 1 Phase 2 103% 96% 1
- 25. #SMX #13B @AndreasReiffen •A / B testing complex campaign setups is possible • Keep results comparable: You should either keep cost stable or revenue stable • Don‘t measure the uplift of the „test“ campaign itself, only the change in relation to „control“ to eliminate seasonality Conclusions for testing Google hacks 1

- 28. #SMX #13B @AndreasReiffen Conclusionsfrom reverse engineering tests • Pure before / after tests need multiple sibling tests to validate: we tested several brands with same results • Look beyond your hypothesis for additional learnings: same traffic at higher CPC was surprising • Always segment out: queries, device, top vs other, search partners, audience vs non-audience. 2

- 31. #SMX #13B @AndreasReiffen Onlyend testing when statistical significance is reached 1 Tipp: Use tools mentioned above to evaluate if data has relevance. Done wrong: eCPC test run for two weeks only. Result is that eCPC does not work. Done right: Consider that Googe algorithm needs time to learn + not enough traffic for statistical relevance. With more data the result is that eCPC does indeed work. eCPC 2,930 +5% CPC 2,8001,010,246 CPC 1,032,007 eCPC -2% Impressions Conversions

What else could influence the test results? 4 Done wrong: Image changes sometimes work, sometimes they don‘t, result inconclusive Done right: Looking at the test environment shows: If competition images are mixed, there‘s no change. If competition images are uniform, there‘s an improvement.
