Find mixed date formats
Finds date columns where day and month are swapped, text and real dates are mixed or years have two digits, and proposes one consistent format.
Check analyses for missing dropouts
Checks whether an analysis only contains the cases that remained, such as active customers, running projects or successful campaigns.
Check lazy-loaded content for findability
Checks whether text, images, product lists and links that only load on scroll or click are visible to search engines.
Check link attributes for ads and user links
Checks whether paid links, affiliate links and links in comments or reviews carry the right attributes such as sponsored, nofollow or ugc.
Check regular expressions for ReDoS
Finds regular expressions that take extremely long on certain inputs, for example because of nested repetition, and proposes safe patterns, length limits and time limits.
Check file paths for directory traversal
Finds places where file names or paths from requests, uploads or archives flow into file access, and checks whether someone could read or write files outside the intended folder with input such as ../.
Check rates for shifting denominators
Checks whether rates in a report are calculated on the same base over time and across teams, and finds places where a changed denominator only fakes an improvement or a decline.
Check spreadsheet exports for formula injection
Checks whether CSV and spreadsheet exports take values from forms or user input unprotected, so cells starting with = + - @ could run as a formula when the file is opened.
Check tag and archive pages for thin content
Checks automatically generated tag, author, date and archive pages for whether they offer value of their own or are just lists with one or two posts, and suggests which stay, are merged or are removed from the index.
Check click depth of important pages
Checks how many clicks important product, category and guide pages are from the home page, and proposes internal links so nothing important is reachable only through long click paths or pagination.
Check caches and loaders for coalescing
Checks places where a cache miss calls the origin and finds missing coalescing of concurrent loads for the same key.
Check multi-step flows for compensation
Checks flows with several write steps for whether a mid-way abort is compensated, retried or clearly marked as failed.
Check A/B tests for peeking
Checks analyses of running or early-stopped A/B tests for whether results were viewed mid-way without a plan and the stop was chosen after a significant interim look.
Check claims against sample size
Checks number claims in reports for whether the sample is large and stable enough and whether relative jumps on tiny bases look exaggerated.
Check faceted URLs in the index
Checks URLs created by filters and facets for whether they are indexed even though they offer little content of their own or inflate crawl load.
Check tracking parameters for URL variants
Finds campaign and tracking parameters that make the same content appear under many URLs, and proposes canonical targets or parameter lists for search.
Check for N+1 queries
Checks code and traces for loading a list and then querying again per item, and estimates the round trips.
Check circuit-breaker gaps
Checks calls to external services for missing breakers, unbounded retries and unclear fallbacks.
Check timestamps for timezone
Checks report columns and exports for naive timestamps and silent local times that shift day boundaries.
Check cohorts for survivorship bias
Checks cohort comparisons for whether dropouts leave the base and success numbers look too high.
Reconcile sitemap and index
Compares sitemap URLs with crawl and index and finds broken entries as well as missing core pages.
Check hreflang conflicts
Checks language and region annotations for missing return links, bad codes and chains that confuse crawlers.
Check fencing tokens on locks
Checks distributed locks for whether a rising token limits write rights after expiry and rejects old holders.
Check consumer lag and backpressure
Checks pipelines for growing lag, missing producer wait and unbounded retries.
