What is the difference between Search Console and Google Analytics?
Both tools are free, both come from Google, and both are accurate. They answer different questions, which is why most site owners end up using the two side by side.
What Google Analytics tells you
Google Analytics tracks what people do once they are on your site: how many came, which pages they looked at, how long they stayed, and where they arrived from, such as Google search, social media or a direct visit.
What Search Console tells you
Search Console shows what happens before the click. It lists the searches that showed your pages in Google, how many people saw them, how many clicked, and the average position. It also tells you if Google has trouble finding or showing a page.
Why you want both
Analytics can tell you that visits from Google fell last week. It does not show the search words people used. Search Console can show which searches lost clicks, but not what visitors did after they arrived.
To understand one site properly, you need to read them together.
One catch: Search Console runs a few days behind
Search Console data usually arrives two to three days late, so the newest days look lower than they will end up. Treat those days as not final before you worry.
When you have several sites
Each site has its own Analytics property and its own Search Console entry, so checking five sites means ten places to look. That chore is why I built Spike Search: one screen that combines both for every site and ranks what needs attention first.
