Junk leads from Google Ads: where they come from and how to cut them

Junk leads from Google Ads come from four places: searches you didn't mean to buy, sites beyond Google Search, people outside your area, and bots or fake form entries. Most of them can be cut with settings and a weekly look at your search terms. Some will still get through, and Google says its own filters don't stop invalid leads on their own.

Key facts

• Search partners are included by default when you create a Search campaign (Google Ads Help).
• The default location setting, "Presence or interest," also reaches people who have only shown interest in your area (Google Ads Help).
• You aren't charged for clicks Google finds invalid, and you may get a credit if it finds them after billing (Google Ads Help).
• Google says its traffic filters "don't prevent invalid leads on their own," because most checks happen after the ad shows (Google Ads Help).

Where do junk leads come from?

Each kind of junk lead has its own cause and its own fix. Match what you see in your inbox to the table before changing anything.

Step 1: Read the search terms report

The search terms report shows the searches that triggered your ads (Google Ads Help). In an insurance account, look for jobs, licensing courses, claims numbers and carrier logins. Each one you find is a search you paid for and can block.

Some low-volume searches are left out of the report for privacy, so it never shows everything. Read it every week while the campaign is new. The negative keywords guide has an insurance starter list and how to scope it.

Step 2: Choose match types on purpose

Broad match reaches the most searches, and the most junk if tracking is weak. Google says broad match can show ads on searches "related to your keyword," using signals such as recent searches and your landing page. Phrase match reaches fewer searches, and exact match gives the most control but the least reach (Google Ads Help).

Google also says to use Smart Bidding with broad match. Smart Bidding learns from the conversions you count, so broad match is only as clean as your tracking. If you can't yet tell a real quote request from spam, phrase and exact match are the safer start.

Negative keywords need care too. Google says they don't match close variants, so you must add plurals and synonyms yourself (Google Ads Help).

Step 3: Check where the ads can appear

A Search campaign can show beyond Google Search in two ways. Search partners, which are other sites and apps, are on by default. Google notes that partner clicks may not always be as targeted. You can turn them off under Networks by unticking "Include Google search partners" (Google Ads Help).

Display Expansion, the "Include Google Display Network" box, shows search ads on display sites. From February 2027, Google says campaigns using it will move to a new channel prioritization setting (Google Ads Help). Check this box on every Search campaign. Turn either network on only if you can measure what it brings.

Step 4: Set the location to Presence

"Presence or interest" is the default and Google's recommendation. It reaches people in your area, people who are regularly there and people who have shown interest in it. "Presence" reaches only the first two (Google Ads Help).

If you can only write policies in the states you target, a shopper elsewhere is a lead you can't sell to. For that reason, Presence is often the better fit. Google says switching away from the default usually lowers impressions, so expect fewer clicks.

Step 5: Protect your forms

Google's guide to invalid leads lists three safeguards for website forms (Google Ads Help):

1. reCAPTCHA on the form, to block simple bots.
2. Double opt-in, an automatic email with a confirmation link, counting the lead only once it is clicked.
3. Server-side checks of the email domain and phone number format before the lead reaches your system.

For lead forms that open inside the ad, Google offers phone number verification with a one-time code, for Search campaigns only. It also lets you mark multiple-choice answers that show a qualified lead (Google Ads Help). The calls or forms guide compares the two.

Stop counting junk as success: Google suggests optimizing for lead goals such as "Request quote" or "Qualified lead," because Smart Bidding finds more of whatever you count (Google Ads Help).

What happens to bot clicks?

Google filters most of them and doesn't charge you. Its help page defines invalid clicks as accidental clicks, automated traffic and clicks meant to raise your costs. They are taken out of your reports and your bill. When Google finds them after you have paid, you may get a credit on a later invoice (Google Ads Help).

Click filtering doesn't cover a fake person who fills in your form. That is why the form safeguards in Step 5 matter.

What if the leads are real but still don't buy?

Then the problem is fit, follow-up or tracking, not spam. Shoppers who want the cheapest price, people who can't be reached and leads that sit for a day all look like junk later. The Google Ads troubleshooting guide helps you find which one it is. Mark each lead as quoted or sold in your own records, and the conversion tracking guide shows how to send that back to Google.
