Not sure which tool fits? Start with the problem: a site update visitors cannot see, tracking numbers that look wrong in a spreadsheet, or a newly published page you want to review. All three tools have English and Chinese versions and a fictional example to try first.
The tools work in your browser. The post-publish review records your answers; it does not fetch or automatically verify your page.
Available tools
Changed your site, but visitors still see the old page?
Does the update show while you are signed in but disappear on a phone or in a private window? Compare three views and see what to check next. Cache headers are optional; the result is a lead, not a confirmed diagnosis.
Tracking-number spreadsheet failing or showing E+?
Before importing, choose a CSV file or paste table text. Confirm the order, carrier, and tracking-number columns, then check for blanks, duplicates, and numbers changed into forms such as 1.23E+17. The tool cannot restore a number already damaged by spreadsheet software.
Published a page? Check what visitors can use.
Check whether visitors can open it, read it on a phone, and use its important links. Review search settings, record what changed, and save a follow-up report. Use Search Console separately to check Google indexing.
Privacy and limits
All three tools process inputs in your browser and do not save your answers in a DocsHook account. The post-publish review temporarily saves progress in the current browser tab; reopening it more than 24 hours after your last action clears it, and you can clear it yourself. It does not fetch the target page or verify your selections. Do not enter passwords, cookies, private customer details, or URLs with secret parameters. These reports cannot prove Google indexing, a live order, a real parcel, or the cause of a caching fault.
