You fixed the canonical issue three weeks ago. Did organic traffic actually move, or did it just feel that way? Connect GA4 and TechySEO lines up session counts, engagement, and conversions against every page in your crawl, so a question like that has a real answer instead of a guess based on a screenshot from before and after.
Try explaining a canonical tag fix to a stakeholder who thinks in revenue and leads, and watch their eyes glaze over. That's not because the work doesn't matter, it's because nobody's shown them what happened to traffic afterward. Without that, "we fixed 40 technical issues this month" is just an activity report, not evidence of anything.
This is exactly what GA4 data fills in. Crawl data tells you a page has a problem. It can't tell you how many people actually land on that page from search, how long they stick around, or whether they convert once they're there. Pair the two and a different question becomes answerable: did engagement or conversion rate actually move on the pages where you fixed something, compared to pages you didn't touch?
That's what this integration is for β connecting a specific fix, on a specific date, to whatever happened to that page's traffic afterward. Not a vague before-and-after screenshot, an actual page-level comparison.
Traffic behavior sitting next to technical health, on the same page-level record, instead of in two tabs you keep switching between.
Connect GA4 once and every fix going forward gets a real before-and-after, on the page it actually happened on.
