G2Data retention defaults to two months and governs every exploration report. Internal traffic is not filtered. Payment providers steal attribution. Twenty minutes of settings, and every day of delay is permanently missing.
4 August 2026The interface presents an estimate, a suppressed row and a census with identical confidence. Sampling, thresholding, consent loss and dark traffic, with the signature and the remedy for each.
4 August 2026If you have ever exported a segment to compare it against last month’s export, you needed a population. Three things a filter cannot do, and how to define membership that stays true.
4 August 2026Mobile is charged for the research and desktop is credited with the sale. How to resolve identity across devices, the three honest methods, and what to measure once the person is whole.
4 August 2026The formula is one line: downstream rate multiplied by downstream value. Being approximately right beats being silent, and a demo at $340 is far more useful than a demo at 1.
5 August 2026Five routine, legitimate changes that make this month incomparable to last while the report keeps rendering. Annotate in the tool, never change mid-quarter, and test filters against history first.
5 August 2026Every analytics implementation that becomes unusable got there by tracking everything available and hoping meaning would emerge from volume. Identity, then one conversion, then the funnel, then revenue, then retention.

4 August 2026Most accounts have between six and fifteen conversions defined. Almost none need more than two. The three-part test, and why the cost of getting this wrong shows up in a bidding algorithm two quarters later.
4 August 2026A session is a timeout window scoped to one browser, so one buyer on three devices arrives as several unrelated rows. Resolving them into people fixes attribution and lifetime value, and costs coverage, consent, and the risk of merging two strangers into one profile. Here is when that trade is worth making.
19 February 2026You cannot steadily grow a business by following hunches. Companies that use analytics to guide decisions consistently outperform those that rely on gut instinct. Here is why, and how to start.
22 March 2025Vanity metrics make you feel good when they go up but do not help you make decisions. Pageviews, total visitors, and time on site are the worst offenders. Here is what to track instead.
26 March 2025The default Google Analytics dashboard is a data puke of vanity metrics. On the Visitors Overview report, there is not one number you should actually care about. Here is how to fix that.

30 March 2025A well-built funnel tells you exactly where you are losing customers and how to fix it. This guide walks through building your first funnel, benchmarking each step, and testing improvements.

7 April 2025A North Star Metric is the single number that best captures the core value you deliver to customers. Getting it right aligns your entire organization. Getting it wrong means optimizing for the wrong thing.
13 April 2025Most teams track 50 KPIs and act on zero. The problem is not too few dashboards. The problem is too many metrics. Limit yourself to 10 and you will make better decisions.
17 April 2025Bounce rate tells you the percentage of visitors who leave after viewing just one page. But a high bounce rate is not always bad. This guide explains the nuance, provides benchmarks, and shows you how to reduce bounces that actually matter.
15 March 2026Time on site is the length of a single visit to your website. Time on page is the length of one pageview inside that visit. Both are calculated from timestamp gaps, which is why the last page of every session records as zero seconds.
15 March 2026Between 2010 and 2018 the Kissmetrics blog took 62 million pageviews and its readers became customers worth $15 million. We still have the per-post revenue data. It shows the most-read content and the most valuable content barely overlapped.
4 August 2026A metric is a single standardized number, like a 2.7% conversion rate. Analytics is the investigation that explains why that number moved and what to change. Here is the difference between analytics and metrics, and how to build a practice that uses both.
15 March 2026The arithmetic is not the hard part. Two of the three inputs are measured and the third is a forecast, which is where the entire error budget lives. What to calculate instead, and why the word doing the damage is "lifetime".
15 March 2026Most analytics tools track sessions, not people. This guide explains the spectrum of visitor tracking methods, from anonymous pageview counting to full person-level identity resolution, and how to choose the right approach for your business.
15 March 2026Bounce rate and exit rate are often confused, but they measure fundamentally different things. Bounce rate measures single-page sessions; exit rate measures where multi-page sessions end. Knowing the difference changes how you diagnose and fix problems.

22 March 2026GA4's event model is powerful in theory but frustrating in practice. Between the 500-event limit, 25-parameter cap, and GTM dependency, most teams track less than they should. There is a simpler way.
22 March 2026The gap between Google Ads clicks and GA4 sessions is one of the most common complaints in digital marketing. This guide explains the 7 causes of the discrepancy and gives you a framework to diagnose and quantify each one.
22 March 2026Ad blockers put google-analytics.com on the same block list as ad servers, so your tracking script never loads. On a typical site that hides 15-30% of visitors, and the hidden segment skews toward your highest-value audience.
22 March 2026Duplicate events silently inflate your conversion numbers and corrupt your funnel data. This guide covers the 6 most common causes and gives you prevention strategies that actually work.
22 March 2026GA4 says 50 conversions. Google Ads says 120. Both are technically correct, but for different reasons. This guide explains the systematic differences and how to reconcile them.
22 March 2026Diagnosis takes an hour. Three of the six causes are configuration bugs that close permanently; the other three are browser policy, consent law and intermediaries rewriting your links, and no GA4 setting touches them.
22 March 2026A sudden traffic drop triggers immediate panic. But before assuming the worst, you need a systematic diagnosis process. Most drops have a technical cause that is fixable once identified.
22 March 2026When GA4 hides your data behind thresholds, you lose visibility into exactly the segments that matter most. This guide explains why it happens and gives you 5 practical workarounds.
22 March 2026Bot traffic inflates your metrics and corrupts every downstream decision. GA4's built-in filters catch some of it, but sophisticated bots require a more layered approach.

2 August 2026An agent has no scroll depth, no dwell time and no session. Everything session-based analytics measures is meaningless for it. Here is what to measure instead.
2 August 2026Blocking training crawlers is cheap. Blocking retrieval crawlers costs you the citations that send real humans. Most robots.txt files do not tell the two apart.
