    "content": "I checked the full table (62,496 rows, 11 websites, 2014–2024) and found no nulls or negative values. The main problems are impossible metric relationships, extreme outliers, zeros that look like placeholders, and a small number of duplicates and format oddities.\n\n**What is clean**\n- There are no nulls in page path, URL, bounce rate, exit rate, page views, unique views or entrances. Every column checked has 62,496 non-null values (steps 0 and 5).\n- There are no negative values, and bounce and exit rates are never outside the valid range (steps 0, 4 and 5).\n- Unique views never exceed page views (`uv_gt_pv` = 0). That is the expected relationship.\n\n**1. Impossible values: entrances greater than page views (the biggest issue)**\n- In 24,648 of 62,496 rows (about 39%), ENTRANCES exceeds PAGE VIEWS. An entrance is itself a page view, so this cannot be true.\n- It is concentrated in www.brla.gov (11,830 rows), brgov.com (9,211), data.brla.gov (2,958), city.brla.gov (243 of its 404 rows) and gis.brla.gov (87 of 147). The by-website breakdown is in the rendered tables.\n- Likely causes are sampling, or entrances and views being aggregated differently, for example by page path versus URL, or by session versus hit. The source system would need to confirm.\n- Treat entrance-based metrics, such as entry-page rankings, as unreliable until this is understood.\n\n**2. Extreme outliers**\n- The median page views per row is 8, the 99th percentile is about 64.5k, and the maximum is 228,326,194. That maximum sits in city.brla.gov, along with a maximum entrances value of 227,064,076.\n- city.brla.gov has only 404 rows, yet its median page views is 2,088. One row there dwarfs everything else and will distort any sum or average. It looks like a site-level total, a root-page aggregate, or a bad load.\n- The next-largest values are much smaller: www.brla.gov peaks at 17.6M views and 16.5M entrances, and my.brla.gov at 2.36M views.\n- gis.brla.gov has a maximum of 1,680,247 entrances against 110,198 maximum page views. That is another case of entrances exceeding views.\n- Use medians or trimmed sums instead of raw totals.\n\n**3. Zeros that look like placeholders or missing data**\n- 7,319 rows have an average time on page of 0 seconds. That is plausible for single-page or bounced visits, but it may also mean the value was not captured. Rows with zero time are spread across the large sites, for example 2,675 in brgov.com and 2,531 in www.brla.gov.\n- 6 rows have zero page views: 4 in budget.brla.gov and 2 in my.brla.gov. A page listed with no views is odd and may be a leftover record.\n- Average time on page runs up to 2,794 seconds (about 47 minutes). That is a long dwell time and probably reflects idle open tabs rather than real reading.\n\n**4. Duplicates and key issues**\n- The stated grain is WEBSITE, YEAR and PAGE URL. 21 keys repeat, covering 42 rows, each repeated twice (step 2). That is minor but should be deduplicated or checked.\n- Page URL counts are lower than row counts for every site, which is consistent with the same URL appearing across multiple years.\n\n**5. Format and consistency issues**\n- www.brla.gov has 2 rows with a whitespace issue (`ws_issue`) and 1 row with a non-HTTP URL (`nonhttp`). The 1 non-HTTP value is the only URL format anomaly. No other site has either problem (step 1).\n- data.ebrgis.opendata.arcgis.com is an external ArcGIS host, not a brla.gov domain. It may be worth treating separately.\n- I found no evidence of mixed units. Time is consistently in seconds and rates are percentages within range. The only mixed-semantics risk is the entrances versus views definition mismatch above.\n\n**Recommendations**\n- Flag or exclude rows where entrances exceed page views, or investigate how they were computed.\n- Exclude or cap the city.brla.gov outlier before any aggregation.\n- Deduplicate the 21 repeated keys.\n- Trim whitespace and check the one non-HTTP URL.\n- Treat zero time on page as unknown rather than as a real zero."
