"Your Change Was Not Applicable to Any Keywords"
This one is searched constantly. It shows up when you try a bulk change (a bid edit, a match type change, a status flip) and Google quietly refuses to apply it to anything you selected. The message itself tells you nothing useful. The actual causes are predictable once you know where to look.
The keywords already have the setting you tried to change. This is the most common cause by a wide margin. You select a batch of keywords, hit pause, and they were already paused. Google returns the error. Same with match type: if you try to switch a group to broad and they are already broad, there is nothing for the edit to do. Obvious in theory. Less obvious when you are looking at hundreds of keywords across a dozen ad groups and cannot tell at a glance what state any of them are in.
Keywords were removed or archived between selection and execution. If you selected keywords, navigated away, came back, and then tried to apply an edit, the state may have shifted. Someone else on the team paused, removed, or restructured them while you were elsewhere. Anyone who shares an account with two or three other operators has hit this.
The bulk edit targeted the wrong scope. Google Ads bulk edits run at either campaign level or ad group level. Pick the wrong one and the system has no matching keywords to act on. It is easy to do when you are deep in a session and clicking fast.
Filter mismatch. Your current filter may be showing one set of keywords in the interface, but the bulk edit is operating on a different set. This bites hardest when you filter by status, label, or search term and then "select all."
The fix: clear filters, re-select the keywords you actually want to edit, and check each one's current status before pulling the trigger. For anything large, do it in Google Ads Editor instead of the web UI. Editor downloads a local copy of the account and applies your edits in a single sync, which is dramatically more reliable. And check the change history before assuming the edit failed. Half the time, an automated rule or another user already applied it.
Google Ads not working: a diagnosis framework
When campaigns stop delivering, or never start, the problem could sit at any layer of the stack. Don't guess. Work through this checklist from the widest scope down. Most of the time you'll find the issue in the first three checks.
Step 1: Account level. Is the account itself active? Check the notification bell for suspension notices. Look at billing. A declined payment method stops the entire account from serving. Review any policy violation flags. A suspended account will not deliver ads no matter how well the campaigns are built.
Step 2: Campaign level. Are the campaigns enabled? Check the status column. Look for campaigns that are paused, removed, or sitting outside their scheduled date range. End dates that quietly passed will stop a campaign serving with no warning. Check the daily budget too. Google will stop showing ads as soon as the daily cap is hit, which can happen early in the day if your bids are aggressive relative to the budget.
Step 3: Ad level. Are the ads approved? Open "Ads & assets" and check the status column. Disapproved ads will not serve. Ads "under review" won't either, and review can take up to 48 hours after a new ad or an edit. If every ad in a group is disapproved, that ad group is effectively dead.
Step 4: Bidding level. Is the campaign "limited by budget" or "limited by bid"? Both statuses mean Google is throttling delivery. "Limited by budget" means your daily cap is too low for the available search volume at your current bids. "Limited by bid" means your bids can't win auctions. In bad cases this drops delivery to almost nothing.
Step 5: Targeting level. Is the audience too narrow? Check location targeting. If you accidentally narrowed it to a single postcode instead of a region, volume will be minimal. Check device adjustments. A -100% mobile adjustment locks mobile out completely. Look at audience exclusions and confirm you haven't accidentally excluded the people you actually want.
Step 6: Conversion level. A campaign can be working in the sense that clicks and impressions are flowing, but still look broken if conversion tracking is busted. Check the "Conversions" column. Zero conversions on reasonable click volume usually means a broken tag, not a broken campaign. Test the tag with Google Tag Assistant or real-time view in Google Analytics before you blame the campaign.
Google Ads not loading
Sometimes the problem isn't your campaigns at all. It's the Google Ads UI. Blank dashboards, half-loaded screens, controls that won't respond. It happens more than Google likes to admit, and every minute spent on it is a minute not spent on actual work.
Clear your browser cache. This fixes most dashboard loading problems. Google Ads is a heavy web app that stuffs a lot of data into your browser cache, and when that cache goes stale or corrupt, the UI breaks. Clear it, or open the dashboard in an incognito window to test.
Disable ad blocker extensions. Browser extensions that block ads can also block the Google Ads interface. Yes, the irony writes itself. They sometimes block the JavaScript or network calls the dashboard relies on. Turn off extensions, reload, and see if the UI comes back.
Check for Google Ads outages. Google Ads goes down periodically. The status dashboard at ads.google.com/status will tell you if it's an outage rather than a you-problem. If it is, you wait. They usually clear in 30 minutes to a couple of hours.
Use Chrome. Google Ads is officially supported on Chrome, and while it usually works elsewhere, Chrome gets the most testing and the fewest UI bugs. If you're hitting weirdness in Firefox, Safari, or Edge, just switch to Chrome before you sink another hour into debugging.
Sign out of multiple Google accounts. Multi-account sign-in confuses the Ads interface about which account's data to load. Sign out of everything, sign back in with only the account that has Ads access, and a surprising number of loading and auth issues quietly resolve.
Most of the time, clearing the cache or switching browsers does it. If you've tried everything above and it still won't load, it's a platform-side problem and you're waiting it out.
Google Ads not converting
Campaigns running, clicks coming in, budget draining, conversion column reads zero. You're paying for traffic that does nothing. The causes usually fall into five buckets.
The conversion tracking tag is not firing. Check this first. It's the most common culprit by a wide margin. Use Google Tag Assistant or GTM's debug mode to confirm the tag fires when someone actually completes the action you care about. Typical failures: the tag was placed on the wrong page, it fires on page load instead of on form submit, or someone removed it during a recent site update. If you've shipped a website change recently, re-verify every conversion tag. Don't trust that they survived.
The landing page is broken. Perfect targeting can't save a broken landing page. Test on desktop and mobile. Submit the forms yourself (a visual inspection isn't a test). Confirm the page loads in under three seconds, because anything slower bleeds visitors before they read a word. And check that the page actually matches the ad. If your ad promotes a specific product and the click drops users on a generic homepage, they bounce.
The wrong conversion action is set as primary. Google Ads lets you mark conversions as "primary" or "secondary." Bid optimisation only uses primary conversions. If you accidentally set a page view or a scroll-depth event as primary instead of a form submission or purchase, the campaign optimises for the wrong outcome. Open Tools > Measurement > Conversions and confirm the right action is the primary one.
Not enough volume on competitive keywords. In some industries you need a minimum click volume before conversions show up at all. If your conversion rate is 3% and you're getting 10 clicks a day, going several days with zero conversions is just maths, not a broken campaign. Work out how many clicks you need given your expected conversion rate, and check your budget can actually deliver them.
Poor search term relevance. You're getting clicks, but from the wrong people. Open the search terms report and look at what users are actually typing when they trigger your ads. If most of it is irrelevant, the problem isn't your tracking or your landing page. It's your targeting. Add negatives, tighten your match types, and re-evaluate. For a systematic approach, our PPC audit guide walks through the full process.
Common Google Ads issues and quick fixes
Not every problem needs a full investigation. Here are six issues you'll hit constantly, and the direct fix for each.
Disapproved ads. Open "Ads & assets" and hover over the status to see the specific policy violation. Usually it's restricted content, a misleading claim, or a trademark issue in the copy. Fix the creative, resubmit, and a review will normally come back within 24 hours.
"Limited by budget" status. Google is telling you the campaign could spend more if you'd let it. Two options: raise the budget to capture the volume, or tighten targeting and bids to get more out of what you've already got. If raising the budget isn't on the table, concentrate spend on your highest-converting keywords and pause the rest.
Extended learning period. Smart Bidding (Target CPA, Target ROAS, Maximise Conversions) enters a learning period after any significant change. Performance wobbles during it. The fix is patience. Stop touching the campaign, give the bid strategy two to three weeks with stable settings, and let it converge. Frequent edits reset the clock and the algorithm never gets where it's going.
Keyword conflicts. The same keyword sitting in multiple campaigns or ad groups competes against itself in the auction. CPCs go up, reporting gets confusing, nothing good. Audit for duplicates, consolidate them into one place, and use negatives to stop campaigns from overlapping. Another keyword status that catches operators off guard is when Google flags terms as low search volume and stops serving them entirely, which looks like a delivery problem but is really a query-volume one.
Low ad strength. Google grades Responsive Search Ads from "Poor" to "Excellent." Low strength means you haven't given it enough variety in headlines and descriptions, or the variations are too similar to matter. Add more headlines with different angles: keywords, benefits, CTAs, USPs. Aim for at least 10 headlines and 4 descriptions per RSA.
Billing errors. A failed payment pauses the whole account. Update the payment method under Tools > Billing > Payment methods, and check you haven't blown past your billing threshold. Once you fix the payment, ads can take a few hours to come back. For persistent billing weirdness or double charges, go straight to Google Ads support.
When to escalate to Google support
Some problems you can't fix yourself. They sit on Google's side. Knowing when to stop digging and just open a ticket saves you hours.
Account suspensions. A policy suspension goes through Google's policy team, full stop. No amount of self-service troubleshooting fixes one. Submit the appeal through the Google Ads interface and attach any documentation that shows the listing or business actually complies with the policy in question.
Merchant Centre product disapprovals. If a product in your Merchant Centre feed is disapproved for a reason that's clearly wrong (a "misrepresentation" flag on a perfectly accurate listing, for example) request a manual review. Automated systems get it wrong all the time, and a human reviewer can usually overturn a bad call.
Billing disputes or double charges. If you've been charged incorrectly or twice for the same period, talk to Google Ads billing support. Don't try to fix it by swapping payment methods or playing with the budget. That just compounds the mess.
Account access issues. Locked out, can't add or remove users, getting auth errors that survive a cache clear? That's a support call. They can verify identity and put you back in.
Platform bugs. Editor not syncing. Reporting numbers that don't agree with each other. UI elements consistently broken across browsers and machines. That's a platform bug, not a you-bug. Report it with screenshots and clear reproduction steps.
When you do contact support, use live chat over email. It's substantially faster. Have your 10-digit account ID ready before you start. Bring screenshots with timestamps and a short list of what you've already tried. Vague tickets get vague responses.
Most of these issues are avoidable if someone is actually watching. Daily checks catch billing failures before the account pauses, catch disapprovals before delivery drops, and catch a broken conversion tag before you lose three days of data. Pace watches your campaigns for you and surfaces this stuff the moment it happens, so you catch issues before they become emergencies. Start a free trial to see it in action.
