Let's do a deep dive\ninto them.\n\n\nIf you're new to Search Console, check out the [introduction to Performance reports](https://support.google.com/webmasters/answer/10268906).\n\nSearch performance basics\n-------------------------\n\n\nThe Performance report contains four metrics that show how your search traffic changes over time.\nWe have an article describing [how each metric is calculated](https://support.google.com/webmasters/answer/7042828),\nand here's a summary:\n\n- Clicks: Count of user clicks from Google Search results to your property.\n- Impressions: Count of times users saw your property on Google search results.\n- CTR (Click-through rate): The click count divided by the impression count.\n- Position: The average position in search results for the URL, query, or for the website in general.\n\n\nEach of those metrics can be analyzed for different dimensions. You can check how each of the queries,\npages, countries, devices, or search appearances driving traffic to your website is performing.\n\n\nThere are many ways to access the Search performance data, including the\n[product interface](https://search.google.com/search-console/performance/search-analytics),\nthe [Search Analytics API](/webmaster-tools/v1/searchanalytics/query),\nthe [Looker Studio connector](/search/blog/2022/03/connecting-data-studio),\nand spreadsheets (requires manual download from the interface).\n\n\nIf you're using the product interface, the dimensions are available through the filters or through\nthe dimensions tables following the chart, as shown in the image below.\n\n\nThis data can be used to find ways to make your website more visible and ultimately get more traffic\nout of Google. For a sample of what type of analysis you can perform, check this\n[sample optimization chart](/search/blog/2022/04/performance-optimization-bubble-chart).\n\nData filtering and limits\n-------------------------\n\n\nBoth the data in the report interface and the data exported are aggregated and filtered in different\nways. Below are the two main limitations to the data: privacy filtering and daily data row limit.\n\n### Privacy filtering\n\n\nSome queries (called anonymized queries) are not included in Search Console data to protect the\nprivacy of the user making the query.\n\n\nAnonymized queries are those that aren't issued by more than a few dozen users over a two-to-three\nmonth period. To protect privacy, the actual queries won't be shown in the Search performance data.\nThis is why we refer to them as anonymized queries. While the actual anonymized queries are always\nomitted from the tables, they are included in chart totals, unless you filter by query.\n\n\nLet's look at an example to make it clearer - note that this is an illustration that takes into\naccount only privacy filtering, but daily data row limits, discussed in the next section, may also\nplay a role, read on to learn more. Let's say the table below shows all the traffic for queries to\nyour website, itemizing the traffic from non-anonymized queries. A typical website will generally\nhave more than four itemized non-anonymized queries, of course, but for purposes of this example,\nwe'll say it's just four that are itemized.\n\n|------------------------------|------------|\n| **Queries** | **Clicks** |\n| classic literature | 150 |\n| poetry | 125 |\n| science fiction | 100 |\n| non fiction | 75 |\n| *Total for itemized queries* | *450* |\n| *Total overall* | *550* |\n\n\nIf you add up all the itemized queries, as the chart shows, there were 450 clicks. There are also\n550 overall clicks to the site. That number is higher because it includes all the itemized clicks\nplus the clicks from anonymized queries, which aren't listed.\n\n\nIn practice, when using Search Console reporting, you may notice this type of discrepancy in two main ways.\n\n1. There is no row for anonymized queries in the report table or API (added here for illustration purposes), so if you sum up clicks for all the rows, you'll not find the same number of clicks as the chart totals. For example in this case you'd see 450 when you sum up the rows, but you'd see 550 in the chart totals.\n2. The anonymized queries are omitted whenever a filter is applied, so there will be a discrepancy if you compare the sum of clicks in the chart totals to the sum of clicks containing `some_string` and not containing `some_string`. In this case, if you use filters to include only queries that contain the word \"fiction\", you'll see 175 clicks, and if you exclude queries that contain the word \"fiction\", you'll see 275 clicks, summing up to 450 clicks, while in the chart total you'll see 550 clicks.\n\n### Daily data row limit\n\n\nDue to limitations related to serving latency, storage, processing resources, and others, Search\nConsole has a limit on the amount of data that can be displayed or exported. These limits won't affect\nthe majority of properties in Search Console. A few very large websites can be affected by this, but\neven for those we believe the remaining data will be large enough to create a representative sample of data.\n\n\nThe maximum you can export through the Search Console user interface is 1,000 rows of data.\nCurrently, the upper limit for the data exported through the [Search Analytics API](/webmaster-tools/v1/searchanalytics/query)\n(and through the [Looker Studio connector](/search/blog/2022/03/connecting-data-studio))\nis 50,000 rows per day per site per search type, which may not be reached in all cases. The default\nreturned by the API will be 1,000 rows, but you can use `rowLimit` to increase it to 25,000\nand `startRow` to pull the rows 25,001 to 50,000 using pagination. Check this guide to\nlearn [how to get the available data](/webmaster-tools/v1/how-tos/all-your-data).\n\n\nFor requests that don't involve query or URL dimensions, such as countries, devices, and Search\nAppearances, Search Console will display and export all the data.\n\nResources and feedback\n----------------------\n\n\nIf you'd like to learn more about the subject, read the [Performance documentation](https://support.google.com/webmasters/answer/7576553).\nYou'll find in-depth explanations about the available data, how to use the Performance report, and more\ndetails about discrepancies you may find in the charts.\n\n\nIf you have any questions or concerns, please reach out to us via the\n[Google Search Central Community](https://support.google.com/webmasters/threads?thread_filter=(category:search_console))\nor on [Twitter](https://twitter.com/googlesearchc).\n\nPosted by [Daniel Waisberg](https://www.danielwaisberg.com), Search Advocate"]]
