How often should I make changes to campaigns that are using Cobiro Label Manager?

There are some principles each Cobiro Label Manager user should keep in mind for the long-term gains from the tool.
1. Campaign optimization with Cobiro Label Manager is ongoing and overall no different than without it. It only becomes easier and at the same time more efficient.
2. Cobiro Label Manager is a data-driven solution so it depends on data coming from Performance Max or Shopping campaigns. If the campaigns were inactive for a week or two, it may cause more products to slide down to lower-performance segments, such as Wasters or Sleepers.
3. Cobiro Label Manager takes into account past product performance, but it can't account for everything - any significant product changes (such as >20% price adjustments), seasonality, or availability may have a small time lag before appearing in the analysis results. 

Given all of the above, we recommend using the following optimization workflow with specific situations altering it:

1. Check the campaign under Cobiro Label Manager every week, ideally on the day after the latest analysis is conducted. This would guarantee that you’re seeing the latest segmentation results. In case of uncertainty, check the last analysis date on the Cobiro Label Manager dashboard and click “Fetch now” on the corresponding supplemental feed in Google Merchant Center, then wait for approximately 2 hours for results to appear in Google Ads.
2. After checking the performance, adjust budgets based on the campaign’s goal where Winners and Prospects should have all the room they need while Sleepers may need to be further restricted.

Other situations, that may require immediate action:
3. Large assortment inflow - The new products are likely to appear in the No-index segment for the first couple of weeks. To give them more breathing room, increase the budget of this segment accordingly to account for the new items in it.

4. High season coming on the market or the niche - Right after it ends, be sure to adjust break-even ROAS accordingly for a week or two in Cobiro Label Manager settings. This would prevent fake Winners from appearing and stealing from the budget based on performance that is no longer there. However, please keep in mind that it should still be about 75% points lower than the actual Target ROAS you expect from your Google Ads campaign (eg. 425% from 500%).
