Up to that point the list feels open-ended. You add an address when something looks wrong, you move on, and the count is invisible. Then one afternoon you paste in a new block and the interface tells you there is no room. Worth saying up front: most accounts never get near 500. If you have added six addresses in two years, this article is not about your problem. It is about what the ceiling tells you when you do reach it, which is usually more interesting than the ceiling itself. For the setting in full, start with our guide to [Google Ads IP exclusions](/google-ads-ip-exclusions/). ## What the Google Ads IP Exclusion Limit Actually Covers Five hundred entries, per campaign, counted as entries rather than addresses. That distinction matters. A range counts as one entry regardless of how many individual addresses sit inside it, which is the only real lever you have for stretching the allocation. The limit does not pool across campaigns. Each campaign gets its own 500 and its own list. In one sense that is generous, since a ten-campaign account technically has five thousand slots. In practice it means ten separate lists to keep current, and there is no native tooling to sync them. Whatever you add to one campaign you add by hand to the rest, or you script it through the API. ### Ranges are how most lists survive If you are excluding addresses one at a time, you will hit the ceiling faster than you expect. Grouping into ranges buys room, at the cost of precision. A wide range is one entry that blocks a lot of people, and some of those people may be prospects. That trade is fine when you are blocking a hosting provider's address space. It is a bad trade when the range covers residential broadband in a city you sell into. ## What Happens When the Campaign Is Full Nothing dramatic. Google does not warn you as you approach the limit, does not degrade the existing list, and does not start dropping old entries to make space. It simply refuses the new one. The existing 500 keep working exactly as before. The real consequence is the decision it forces. To add anything new you have to remove something old, and you almost certainly have no idea which of the 500 is still earning its place. Nothing in the account tells you how many clicks an exclusion has prevented, because prevented clicks do not generate data. An entry you added eighteen months ago against a competitor who has since changed ISP looks identical to one blocking an address that hammers you daily. So the list gets pruned by guesswork. Oldest first, usually. That is not auditing, it is rotation, and the accounts that end up doing it tend to be the ones that most need something better. ## Why a Full List Is Usually a Symptom Here is the part that matters more than the number. A campaign that has genuinely accumulated 500 justified exclusions is not telling you that the limit is too low. It is telling you that the traffic hitting that campaign changes address faster than you can write addresses down. Manual blocking assumes a stable adversary. You identify the source, you block it, it stays blocked. That assumption holds for a competitor clicking from their office and for an annoyed former customer on a static connection. It stops holding the moment the traffic is automated or routed through anything that cycles addresses. Then every block you add is retroactive, aimed at a location the traffic has already left. When you find yourself pruning a full list to make room for more, the list has become a treadmill. The addresses keep coming because the underlying source is not address-bound. ## What to Do When You Reach the Ceiling A few things are worth doing before you conclude the tool has failed you. - **Consolidate into ranges.** Individual entries from the same block can often collapse into one. This alone recovers meaningful room in most full lists. - **Date your entries.** Keep the list in a spreadsheet with the date and reason for each exclusion, so pruning is informed rather than arbitrary. Google will not store this for you. - **Check whether the campaign still needs them all.** Exclusions added for a campaign that has since changed targeting entirely may be protecting nothing. - **Audit what the entries have in common.** If most of them resolve to hosting providers or data centers rather than homes and offices, you are dealing with automated traffic and the list was never going to keep up. ## The Limit Is Not Your Actual Problem It is tempting to treat 500 as an arbitrary restriction Google should raise. Raise it to five thousand and the treadmill just runs longer. The constraint that hurts is not the ceiling, it is that you are identifying sources by hand, after the money is gone, with no feedback on whether any given block is still doing work. Google's own response to invalid traffic runs on the other side of the timeline. It detects, then credits, and those credits arrive after the click was served and billed. The detection criteria are not published, so you cannot see what was caught or what slipped through. We go through what that covers in our piece on [Google's invalid click refunds](/google-invalid-click-refunds/). Useful, but not the same thing as never paying for the click. Prevention is the part worth buying. Automated [click fraud protection](/click-fraud-protection/) exists to handle the identification and blocking continuously, so the question of which 500 addresses deserve the slots stops being something you decide manually at midnight. ## The Short Answer Five hundred exclusions per campaign, ranges count as one, no account-level pooling, no warning as you fill up, and no way to tell which entries are still working. Use ranges, keep your own records, and treat a full list as a signal rather than an inconvenience. If a campaign has filled its allocation, the addresses are not the problem. Whatever keeps generating new ones is.
