เมื่อแคมเปญ Performance Max แสดงแล้ว คุณอาจต้องการเปรียบเทียบ
ประสิทธิภาพกับแคมเปญที่มีอยู่เพื่อทําความเข้าใจว่าแคมเปญ
สร้างมูลค่าที่ใดและคุณอาจต้องการปรับปรุงที่ใด
ก่อนเปรียบเทียบประสิทธิภาพของแคมเปญ ขอแนะนําให้คุณใช้งานแคมเปญเป็นเวลาอย่างน้อย 6 สัปดาห์เพื่อให้ AI ของ Google เรียนรู้และดูแลจัดการข้อมูลมากพอที่จะเปรียบเทียบประสิทธิภาพ

Make sure to compare the performance of all existing campaigns with exposure to the audiences Performance Max can reach. This will ensure you see the whole picture. This guide will explain new reporting views to access performance data and the best mapping you can make between similar sources.\n\n### Asset groups instead of ad groups\n\nPerformance Max campaigns use the concept of\n[asset groups](//support.google.com/google-ads/answer/10724748) which are a set\nof creatives that will be used to create an ad depending on the channel it's\nbeing served on. Similar to ad groups in other campaigns, you should use them\nto group assets, such as text, images and video, by a common theme.\nGoogle AI will assemble the assets in an asset group into all applicable ad\nformats for your goal and show the most\nrelevant creative for your campaign.\n\nAlthough the specific resources (asset group assets and ad group ads) in both\ntypes of group are different it is a good place to start investigating\ncomparable performance especially if you used the data from an existing ad group\nto create an equivalent asset group.\n\nHere are a few examples of resources and reporting views that are similar\nin Performance Max:\n\n| Your current resource or view | Performance Max similar resource or view | Notes |\n|-----------------------------------------------------------------------------------|-------------------------------------------------------------------------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| [ad_group](/google-ads/api/fields/v21/ad_group) | [asset_group](/google-ads/api/fields/v21/asset_group) | As both group by theme, metrics such as [conversions](/google-ads/api/fields/v21/asset_group#conversions) can be compared for the theme. |\n| [ad_group_ad](/google-ads/api/fields/v21/ad_group) | [asset_group](/google-ads/api/fields/v21/asset_group) | As a collection of assets are used to generate ads, some structural data can be found at this level, such as [final_urls](/google-ads/api/fields/v21/asset_group#final_urls). |\n| [ad_group_criterion.listing_group](/google-ads/api/fields/v21/ad_group_criterion) | [asset_group_listing_group_filter](/google-ads/api/fields/v21/asset_group_listing_group_filter) | Only for campaigns with product or listing groups. |\n| [product_group_view](/google-ads/api/fields/v21/product_group_view) | [asset_group_product_group_view](/google-ads/api/fields/v21/asset_group_product_group_view) | Only for campaigns with product feeds. |\n\n### Search Terms Performance\n\nIf you are looking for metrics on search term performance, use\n[`campaign_search_term_view`](/google-ads/api/fields/v21/campaign_search_term_view) to find data\nfor both Performance Max and search network campaigns aggregated at the campaign\nlevel. Use this view instead of the\n[`search_term_view`](/google-ads/api/fields/v21/search_term_view), which aggregates at the ad\ngroup level and does not include data for Performance Max campaigns.\n\nIn addition to performance metrics, the [search term\ninsights](//support.google.com/google-ads/answer/11386930) report can help you\nunderstand how your customers search and engage with your business on Google.\nThis report analyzes search terms where your ads appear in the selected time\nperiod, grouping them into search categories and subcategories to provide you\nwith key performance metrics for each. For search term insights, segment metrics\nto aggregate at the appropriate level using either\n[`customer_search_term_insight`](/google-ads/api/fields/v21/customer_search_term_insight)\n(aggregate at the campaign level) or\n[`campaign_search_term_insight`](/google-ads/api/fields/v21/campaign_search_term_insight)\n(aggregate at the ad group or asset group level).\n| **Note:** We recommend that you request the `customer_search_term_insight` data first and then refine your request using the `campaign_search_term_insight`. This is due to the volume of data required to be processed when segmenting at lower granularity. You may get a `RESOURCE_EXHAUSTED` error if you use `campaign_search_term_insight` too often on an account.\n\nOptimization \\& Troubleshooting\n-------------------------------\n\nFor more best practices for optimizing and troubleshooting Performance Max\ncampaigns, see our\n[Performance Max optimization and troubleshooting guide](/google-ads/api/performance-max/troubleshooting)."]]
