Why can a blocked IP still appear in ClickPatrol?

Seeing a previously blocked IP appear again is uncommon, but it can happen in a small number of situations. In most cases, Google Ads IP exclusions prevent future ad clicks from excluded addresses.

When a blocked IP does appear again, one of the following explanations may apply.

1. The IP was initially excluded from a specific campaign#

When ClickPatrol first detects suspicious activity, it may only affect one campaign. ClickPatrol may initially apply the exclusion to that campaign rather than across the entire account. If the IP later reaches another campaign, you may see it appear again.

2. Google Ads limits campaign-level IP exclusions#

Google Ads allows up to 500 IP exclusions per campaign. ClickPatrol manages exclusions to keep them focused on IPs that currently pose the greatest risk. An IP that was previously excluded may no longer be on the current list.

3. IP addresses can change reputation#

Not every IP remains suspicious forever.

Residential proxy addresses may disappear after a short period. Many people share VPN exit nodes, and internet providers reassign IP addresses. An IP that appeared suspicious earlier may later be used by a legitimate visitor.

ClickPatrol continuously evaluates traffic so exclusions stay focused on higher-risk activity instead of permanently blocking addresses that no longer pose the same risk.

4. Not every request is a paid Google Ads click#

ClickPatrol tracks visits using tracking parameters. Occasionally, automated systems such as website monitoring tools, link preview services, or security scanners request URLs containing those parameters.

A request appearing in your ClickPatrol logs does not necessarily mean Google Ads charged you for a new click.

5. The same GCLID can appear in more than one request#

The Google Click ID, or GCLID, helps identify and attribute Google Ads traffic. Redirects, browser refreshes, or repeated requests can cause the same tagged URL to be requested more than once.

A repeated GCLID alone cannot tell you whether Google Ads counted or billed a new click. Multiple ad clicks can also share a GCLID.

6. The exclusion may not have taken effect when the visit occurred#

Compare the visit time with the time the exclusion was applied. A visit that happened before the exclusion may appear in ClickPatrol afterward. New clicks can take up to 30 minutes to appear in Click Insights.

Why ClickPatrol doesn’t rely on IP addresses alone#

An IP address does not uniquely identify a person. Schools, offices, hotels, mobile networks, and internet providers can have many users sharing the same public IP address.

That’s why ClickPatrol evaluates multiple signals, including IP reputation, behavioural patterns, and device characteristics, to determine whether traffic is suspicious. This helps reduce invalid traffic while avoiding unnecessary exclusions of legitimate visitors.

The bottom line#

IP exclusions help reduce unwanted Google Ads traffic, and ClickPatrol manages them on your behalf. If you see a previously blocked IP again, you can analyze the click by checking which campaign it came through, when the visit occurred, and whether it was a new paid ad click.
