Configure a shared Meta Pixel for development and production with GTM. Add environment to Lead, define custom conversion rules, and verify ad set selection.
Because UTM values are free text: the table you wrote is read only by you, while GA4 reads the same string by its own rules. Google's published default channel group logic checks source against a list of 819 sites and checks medium against fixed regular expressions, so for one identical link your table says referral and GA4 counts it as Organic Search. The convention document is only half the job. The other half is pulling out the violations with a query on a schedule.
Business questions, not event names. Once the questions are settled the event list follows, and the real decision after that is whether each value gets sent as a parameter or left out and recovered later through a join. In a sheet covering 46 events, 14 parameters were marked as not sent, and the reasons split five ways.
Exposure is not one thing. It splits into paid, organic search, owned media, and earned. Ad platforms report only the first, and the other three each need a different tool. On top of that the word impression means different things per platform, since Google counts when the ad is served and Meta counts when it is on screen.
Search Advisor does report impressions, clicks and CTR. But it lists search keywords only for the top 30 by clicks, does not provide the exposure ranking, and no console answers how competing domains divide those slots. So I opened the search results for 77 keywords every week and counted the slots one by one, and out of 380 slots exactly 4 were ours, all of them near the top.
GA4 starts counting at the moment someone arrives on your site. Anyone who clicked the link but disappeared before arriving never shows up in any report. To measure that stretch, the link has to stop somewhere you control instead of going straight to the destination, and that is exactly what tracking links and MMPs do.
Naver doesn't use external backlinks as a ranking signal. Backlinks aren't in the Search Advisor guide at all, authority builds through source trust (C-Rank), content quality (D.I.A.), and UGC instead. A practical breakdown of six steps for finding topics with search data, plus the four GEO elements that get you cited by AI.
How to trace the true source of branded-search conversions using GA4 attribution. Covers the structural limits of first-touch tracking and the dark funnel, and a ledger-versus-estimate framework for measuring PPL effects.

A beginner's guide to GA4 attribution. Why user scope and session scope show different #1 channels, the four retired models and the data-driven attribution (DDA) that remains, the key event lookback window (30/90 days), and how to read first touch and last touch together.
How to manage tags with Google Tag Manager (GTM) without touching code. Covers the container, tag, trigger, and variable concepts, dataLayer, preview and version control, and the four mistakes beginners make most often.
A live test of why UTM parameters and gclid get lost in cross-domain conversions, and how Claude's site (claude.com) designed pixel-free ad tracking. Includes results from a Naver click ID (NaPm) experiment.
A UTM parameter is a set of five tags appended to a link that tells an analytics tool like GA4 which channel, medium, and campaign a visitor came through. From the 3 required fields (utm_source, utm_medium, utm_campaign) to 5 common mistakes, all in one guide.
How to measure ad channel effectiveness without individual tracking. Covers why a 0.15 correlation was an illusion, the baseline, lift, and adstock (advertising carryover effect) concepts, and the time-series data you need to start stacking today.
What the dark funnel is, why so much traffic ends up logged as "direct," and 6 ways to track it, from UTM discipline to surveys, brand search volume, and experiments, laid out as an explainer guide.
How to self-diagnose where your company's marketing data is missing, using five layers (supply, demand expression, acquisition, conversion ledger, confirmation) and 15 questions. Includes a map of the whole series onto the five layers.
For free, you can see search interest (a relative value) in Naver DataLab, while actual monthly search volume (an absolute value) is checked in the Naver Search Ads Keyword Tool. Covers the principles behind Search Console, Search Advisor, DataLab, and Google Trends.
The Meta Pixel is JavaScript that observes visitor behavior and sends it to ad platform servers. Click IDs like gclid and fbclid match a click to a later conversion, and server-side methods like the Conversions API bypass the browser to recover conversions cookies would otherwise miss.
A GA4 session is a bundle of interactions cut off after 30 minutes of inactivity, and the user count isn't a count of people, it's a count of browser-level cookies (client_id). A ground-up rundown of the basics: cookies, sessions, events, and GA4.
What computer do you actually need to run AI and LLMs? Cloud AI like Claude and ChatGPT needs no graphics card, just 32GB of RAM. Running models locally is a different story: a usable 32B model needs 24GB of VRAM or 48GB of Mac unified memory, and 70B and up realistically needs 128GB on a Mac.
A personal knowledge management (PKM) system where AI, not you, classifies, summarizes, links, and updates your notes. You view it in Obsidian; the AI works from one rules file. A guide from folder structure to a 30-minute setup.
Does bolting memory onto an AI make it smarter? Across five weeks of session logs, only 15% of skills and 4% of reference docs were ever reopened. 96% of the knowledge was a write-only grave. A hands-on log of redesigning AI memory to wire in resurfacing first.
How to use a domain email like hello@mcpy.kr without a server or paid subscription. Step-by-step from Gabia nameserver delegation to Cloudflare Email Routing (MX, SPF, DKIM, DMARC), Gmail Send mail as, app passwords, and spam filters.
Notes pile up but become useless because there is no circulation. I spent a day with AI grafting four circulation loops and automated health checks onto a knowledge vault, and the first checkup found 22 silently broken files. A hands-on build log.
AI image generators break Korean text, logos, and exact pixel dimensions. The fix: generate only the background scene with AI (Claude delegates to Codex imagegen), then layer Korean text and logos via HTML with web fonts, captured to PNG with a headless browser. A build log for automating blog illustrations and OG cards.
Why a polished card disappears in chat previews, the 9px math, gaze cueing, and contrast, plus a complete pipeline from keyword research and page titles to SERP checks, card production, and spreadsheet-driven operations.
Why a carefully crafted OG image turns into a blurry smear in KakaoTalk (Korea's dominant messenger app). The 9px math of canvas vs. render, how gaze-cueing works, URL cache invalidation, and why 7:1 WCAG contrast is the real minimum, all traced back to primary sources.
A case study dissecting how early Christianity grew from roughly 1,000 followers to 35 million over 350 years, analyzed through nine growth marketing levers: addressable market, value, price, channel, promotion, segmentation, people, process, and growth engine. Historical figures are academic estimates.
A brand brief is the single shared input for market-research, positioning, growth, and content agents. Without it, every agent fills in its own assumptions which then contradict one another. The secret to a good brief is honestly marking unknown fields as TBD rather than guessing. Includes a 10-section template and a real example.
Hundreds of notes piled up but AI still had to open every file to answer a simple question. I thought a full ontology would fix it. A lightweight index layer built from existing frontmatter turned out to work 2.9-13.3x cheaper. This is the build log.
Why GA4 user properties show undefined after login, and how to trace GTM data layer timing, repair the setup, and connect user data to revenue analysis.
