Google Ads terms in plain English

The words you’ll see inside your account, in 20 words or fewer.

  • CPC. Cost per click. What you pay Google each time someone clicks your ad.
  • CTR. Click-through rate. The share of people who see your ad and click it. If yours is low, see Google Ads not getting clicks.
  • Conversion rate. The share of clicks that turn into an enquiry, call or sale. If yours is low, see how to improve your website conversion rate.
  • Cost per lead. Your ad spend divided by the number of leads it brought in.
  • ROAS. Return on ad spend. Sales value divided by ad spend, used by online shops. See ecommerce ads.
  • Quality Score. Google’s 1 to 10 rating of your keyword, ad and landing page. A higher score can lower your costs. Quality Score, explained.
  • Search terms report. The real searches that triggered your ads. Check it weekly for waste.
  • Negative keyword. A word that stops your ad showing, like “free” or “jobs”.
  • Match types. How closely a search must match your keyword: broad, phrase or exact.
  • Performance Max. A campaign type that shows your ads across Search, YouTube, Maps and more.
  • Impression share. How often your ad showed, out of all the times it could have.

Questions about running your own ads

How do I know if my Google Ads are wasting money?

Start with the search terms report. It lists the real searches that triggered your ads, and any that would never become customers are wasted spend. Then check your tracking. If enquiries aren’t recorded, Google can’t tell good clicks from bad ones. Our Google Ads checklist covers the rest, or claim a free PPC audit and we’ll check for you.

How much should I spend on Google Ads?

Work back from the leads you want. Divide the leads you need by your conversion rate to get the clicks, then multiply by your cost per click. Our free Google Ads budget planner walks through this maths with worked examples. The free Google Ads budget calculator works it the other way: enter a budget and see the clicks and enquiries it could buy. As a starting point, we suggest at least £300 a month for local campaigns and £600 or more for UK-wide. See how we set budgets.

What’s the difference between the checklist and the free PPC audit?

You use the checklist to check your own account. With the free PPC audit, we check it for you, using read-only access so we can’t change anything. You get a ranked list of fixes within 2 working days. There’s no obligation to hire us afterwards, and the list is yours to keep.

Do I pay Google and an agency separately?

Yes. Your ad spend is paid straight to Google from your own account, so you own the account and its data. Our time is billed separately at £30 an hour. Management plans run from £90 a month for 3 hours (Ads Starter) to £300 a month for 10 hours (Ads Pro).

Rather we ran your ads for you?

You keep your own Google Ads account. We charge £30 an hour, with no tie-ins.
