Surf-N-Board sells a lot of boards in-store and they want to make sure their offline data is taken into account for optimization efforts. What's a best practice for working with offline data?

Uploading offline conversion data files in the order conversions occurred ensures that DoubleClick Search (DS) processes the data chronologically, which is crucial for accurate attribution and optimization. If data is uploaded out of order, DS might misattribute conversions or incorrectly apply bid strategies, leading to suboptimal performance. Uploading in original formatting might not be compatible with DS's required format. Uploading only if conversions occurred could lead to gaps in data, hindering comprehensive optimization. Uploading once a month is too infrequent for effective real-time optimization, as DS benefits from more regular data updates to react to performance changes promptly.
