What Is GSC? Google Search Console explained for business owners

GSC is Google Search Console: Google’s free tool that shows how your website appears in Google Search. It tells you which searches show your pages, how often people click, which pages Google has indexed and which it left out, and when something on your site is broken in a way Google can see.¹

It is the only place where Google itself reports on your site. Analytics tools see what visitors do once they arrive. GSC sees what happens before: in the search results, where most visitors decide whether to come at all.

What GSC shows you

GSC has many screens, but a business owner needs only a few of them:

• Performance. The searches that showed your site, with four numbers for each: clicks (people who came from Google), impressions (times your site appeared), click-through rate (clicks divided by impressions) and average position (where your best result usually sat).² This is the screen that tells you what Google thinks your site is about.
• Pages (indexing). Which of your pages Google has added to its index and which it left out, with a reason for each. A page that is not indexed cannot be found in Google at all.
• URL inspection. The state of one page as Google sees it, and a button to ask Google to look at it again after you change it.¹
• Sitemaps. The list of pages you hand to Google, and how many of them it found.
• Links, experience and security. Which sites link to yours, how fast your pages feel to real visitors, and any manual penalty or security problem Google found.

You don’t need GSC to appear in Google: Google finds sites either way.¹ You need it to see what Google sees.

What GSC doesn’t tell you

Reading GSC well starts with knowing its limits. Four matter most:

• It stops at the click. GSC knows someone came from Google; it doesn’t know what they did next, whether they called, bought or left. That is your analytics tool’s job. The two never show the same numbers, and both can be right.
• Rare searches are hidden. For privacy, Google leaves out searches made by very few people. They still count in the totals, but they are missing from the table, so the list never adds up to the total.³
• The table stops at 1,000 rows, and new data usually arrives two to three days late.³ The newest days on the chart can still change.²
• It keeps 16 months. Anything older is gone unless you saved it yourself.⁴ If you want to compare this year with three years ago, start keeping a copy now.

Three questions to answer with GSC every week

You don’t need to read every screen. Ten minutes a week with three questions catches most problems early:

1. Are the clicks going up, down or flat, compared with the same weeks last year? Compare with last year, not last week: many businesses are seasonal.
2. Which searches show us often but rarely bring a click? Those are pages Google already trusts, with a title or description that doesn’t convince the person searching. Often a one-line change.
3. Did any page that earns money drop out of the index? Check your service and product pages in the Pages screen. A page that falls out stops bringing anyone, silently.

Our own site is a good example of question two. One of our articles appeared in Google’s results 118 times between 1 and 25 October, at an average position near 10, with no clicks at all. GSC showed us that in a minute; no other tool would have. The rest of this series takes each of these questions in turn.

Where to go next

If you don’t have GSC yet, setting it up takes about fifteen minutes; the next part of this series shows how, and who in the company should have access. If you have it and want a second pair of eyes, our free website audit checks what Google can see from the outside, and the deep audit reads your own GSC data, with read-only access, to find the searches and pages worth money.
