51.LA Daily Traffic Comparison

Compare yesterday's traffic with day-before-yesterday for one or more 51.LA sites. Concise per-site output suitable for batch reporting.

Step 0: Know Your Sites

Before starting, know all sites on the 51.LA account:

• URL: https://v6.51.la/user/application
• Extract: site name, domain, and comId (numeric ID shown alongside the site name)
• If login is required: https://v6.51.la/user/login
  • Account: <YOUR_51LA_ACCOUNT> / Password: <YOUR_51LA_PASSWORD>
  • After login, navigate to 应用管理 to get comId values

Step 1: Navigate to Traffic Trend Analysis

agent-browser open "https://v6.51.la/report/trend?comId=<comId>"

Step 2: Select Yesterday's Data

On the trend page:

• Click 昨日 button (e50) to show yesterday's data
• Screenshot → AI extract: IP, PV, UV, 跳出率, 平均访问时长

Step 3: Select Day-Before-Yesterday's Data

• Click 前日 button (e49) to show day-before-yesterday's data
• Screenshot → AI extract: IP, PV, UV, 跳出率, 平均访问时长

Alternative: Use date range for precise comparison

• Use date inputs (e55, e56) to set start and end dates
• e55 = start date, e56 = end date
• Set to yesterday's date for one, then前日's date for the other

Step 4: Repeat for All Requested Sites

Loop through each site's comId, extracting yesterday and day-before-yesterday metrics.

Step 5: Compile Concise Comparison Report

Output Style

• Use Chinese throughout
• Concise per-site blocks (~10 lines each)
• Summary table for cross-site comparison
• ↑ for increase (green), ↓ for decrease (red), — for no change
• 变化 = (昨日 - 前日) / 前日 * 100%，round to 1 decimal
• 跳出率变化用百分点 (pp) 而非百分比
• Total report should stay under ~300 lines even for 20+ sites

Tips

• For batch sites, process each comId in sequence and aggregate into the summary table
• If yesterday's numbers are 0 or missing (site may have just been added), skip that site and note in summary
• 平均时长 comparison: convert to seconds first, then calculate percentage change
• PV/UV ratio: divide PV by UV (e.g., PV=1000, UV=200 → PV/UV=5.0), show 1 decimal place
