How to Fix Low Quality Traffic in Google Ads: A Step-by-Step Guide

You're getting clicks. Your budget is draining. But conversions? Barely there.

If that sounds familiar, you're likely dealing with low quality traffic in Google Ads — clicks from people who were never going to buy, sign up, or do anything useful on your site. This is one of the most common and costly problems advertisers face, and it usually comes down to a few fixable issues: broad match keywords pulling in irrelevant search terms, missing negative keywords, and campaign settings that cast too wide a net.

Here's the important distinction to understand before we dive in. In Google Ads, keywords are the terms you bid on. Search terms are the actual queries users typed that triggered your ads. These two things are often very different, and that gap is where low quality traffic is born.

The good news is that you don't need to rebuild your campaigns from scratch. With the right process, you can tighten your targeting, cut wasted spend, and start sending your budget toward people who actually convert. This guide walks you through exactly how to do that, step by step, inside Google Ads. No spreadsheets required.

Step 1: Diagnose the Problem Using Your Search Terms Report

Before you fix anything, you need to see what's actually happening. The Search Terms Report is your starting point — it shows you the real queries that triggered your ads, not just the keywords you bid on.

To find it, go to your Google Ads account and navigate to Campaigns, then select a campaign, and click Search terms in the left navigation. You can also access it via Keywords > Search terms from the main left nav. This report is where the truth lives.

Once you're in, start looking for patterns. You're scanning for a few specific types of low-intent search terms:

Informational queries: Terms like "how does X work," "what is X," or "X explained" suggest someone in research mode, not buying mode. These clicks cost money but rarely convert.

Competitor brand names: If you're not intentionally running competitor campaigns, appearing on searches for a competitor's brand name is usually wasted spend.

Unrelated industries or topics: Broad match keywords can pull in queries from completely different contexts. A keyword like "project management" might trigger ads for searches about construction project management when you sell software for marketing teams.

Zero commercial intent: Terms with "free," "DIY," "template," or "sample" often signal someone who isn't looking to spend money.

Sort the report by cost, highest to lowest. This surfaces the irrelevant search terms that are actually draining your budget the fastest. Then filter for a meaningful time window — typically 30 to 90 days depending on your traffic volume — and flag any search terms with notable spend but zero conversions.

Don't just skim the top ten results. Scroll through the full list. Low-cost terms that appear frequently can add up to significant wasted spend over time.

By the end of this step, you should have a clear, prioritized list of irrelevant or low-intent search terms that are costing you money. That list becomes the foundation for everything that follows.

Step 2: Audit Your Keyword Match Types

Once you know which search terms are causing problems, the next question is: why are those queries triggering your ads in the first place? The answer is almost always match types.

Match types control how closely a user's search query needs to match your keyword before your ad is eligible to show. Here's how they work:

Broad match gives Google the widest latitude. Your ad can show for searches that are loosely related to your keyword, including synonyms, related topics, and queries that Google's algorithm interprets as relevant. This is the default match type when you add a keyword without specifying otherwise, and it's the most common source of low quality traffic.

Phrase match requires the search to include the meaning of your keyword, in order, though additional words can appear before or after. It offers more control than broad match while still allowing some variation.

Exact match is the tightest option. Your ad shows only when the search query matches your keyword closely in meaning, with little room for variation. This gives you the most control but limits reach.

Go through your keyword list and identify which keywords are set to broad match. For each one, cross-reference the search terms that keyword is generating. If a broad match keyword is consistently pulling in irrelevant queries, that's a signal to either tighten the match type or pair it with a stronger negative keyword strategy.

Tightening match types on high-spend, low-conversion keywords is often the right first move. Switching a broad match keyword to phrase match can meaningfully reduce irrelevant traffic without cutting off all reach.

That said, don't eliminate broad match entirely. It has real value for discovery — finding new search terms you hadn't thought to bid on. The key is that broad match keywords need to be actively managed with negative keywords. Without that discipline, broad match becomes a budget drain.

One common mistake: switching every keyword to exact match in one go. This can tank your impression volume and cut off traffic you actually wanted. Make targeted adjustments based on what the data shows, not a blanket policy change.

By the end of this step, every keyword's match type should reflect a deliberate decision based on performance data, not whatever the default happened to be when the campaign was set up.

Step 3: Build and Expand Your Negative Keyword List

Negative keywords are the most direct lever you have for cutting low quality traffic. They tell Google: do not show my ads when someone searches for this. If you haven't built a solid negative keyword list yet, this step will likely have the biggest immediate impact on your traffic quality.

Start with the flagged search terms from Step 1. These are your highest-priority negatives because they're already costing you money. Add them as negative keywords, but think carefully about the right level to apply them:

Ad group level: Use this when a term is irrelevant for one specific ad group but might be relevant for another. For example, "free" might be a negative at the ad group level for a paid software product, but you might want to keep it active in an ad group promoting a free trial.

Campaign level: Use this when a term is irrelevant across all ad groups within a campaign.

Account level (shared negative keyword list): Use this for terms that should never trigger any of your ads, regardless of campaign. Things like competitor brand names you're not targeting, completely unrelated industries, or terms that consistently attract zero-intent traffic.

When you add negative keywords, also think about match type. Negative phrase match and negative exact match are usually the safest choices. Negative broad match for negatives can sometimes block more traffic than you intended, because it prevents your ads from showing on any search that contains all the words in your negative keyword, in any order.

Some common categories worth building out as negatives:

Informational intent: "how to," "what is," "guide," "tutorial," "explained," "definition"

Non-commercial intent: "free," "DIY," "template," "sample," "download"

Unrelated geographies: If you only serve certain regions, add location terms for areas you don't cover.

Competitor names: If you're not running intentional competitor campaigns, add competitor brand names as negatives.

If you want to speed up this process, Keywordme's Chrome extension lets you add negatives directly from the Search Terms Report with a single click, without leaving Google Ads or opening a spreadsheet. You can flag an irrelevant search term and add it as a negative right there in the interface, which makes the review cycle significantly faster.

The goal is a search terms report that shows progressively fewer irrelevant queries each week as your negative keyword list matures.

Step 4: Review Your Campaign and Ad Group Structure

Sometimes low quality traffic isn't just a keyword or match type problem — it's a structural one. Poorly organized campaigns make it harder to control which ads show for which queries, and they can create keyword cannibalization where multiple ad groups compete for the same search terms.

The principle to apply here is tight theming. Each ad group should cover a specific topic or intent cluster. When an ad group contains keywords with very different intents, Google has to make judgment calls about which ad to show and which landing page to send traffic to — and those calls aren't always the right ones.

For example, if a single ad group contains both "buy running shoes" and "running shoe reviews," you're mixing purchase intent with research intent. Someone searching for reviews isn't ready to buy. Split those into separate ad groups so you can tailor the ad copy and landing page to each intent.

Beyond ad group structure, check two specific campaign settings that often contribute to low quality traffic:

Search Partners: This setting allows your ads to appear on Google's search partner sites. Traffic quality from these partners can vary significantly. If you're seeing high spend with low conversion rates and you have Search Partners enabled, try disabling it and monitoring the impact.

Display Network: If your Search campaign has "Display Network" enabled in the settings, your ads may be showing on display placements — a very different audience context from someone actively searching. For most Search campaigns, this should be turned off.

Also review your audience targeting and bidding settings. Broad audience targeting combined with broad match keywords amplifies low quality traffic problems. These settings compound each other, so tightening one without addressing the other only goes so far.

By the end of this step, each ad group should have a clear, single theme, and your campaign settings should reflect deliberate choices rather than defaults you never revisited.

Step 5: Check Your Landing Page Alignment

Here's a less obvious cause of apparent low quality traffic: the problem isn't always who's clicking. Sometimes it's what they find when they arrive.

If someone searches for "project management software for agencies," clicks your ad, and lands on a generic homepage with no mention of agencies, they'll leave. That bounce looks like low quality traffic in your metrics, but the traffic itself might have been perfectly qualified. The disconnect was between the ad's promise and the landing page's delivery.

To check for this, go back to your Search Terms Report and look at the terms that are generating clicks but no conversions. Then visit the landing pages those clicks are being sent to. Ask yourself: does this page directly address what someone searching that term would expect to find?

Specifically, check for alignment between:

The search term's intent and the landing page's headline. If the headline doesn't reflect what the user was looking for, they'll bounce before reading further.

The ad's promise and the landing page's content. If your ad mentions a specific feature, offer, or use case, the landing page should lead with it — not bury it three scrolls down.

The call to action and where the user is in the buying process. Someone searching an informational query might need more context before a "Buy Now" CTA makes sense. A landing page that skips straight to the hard sell for a research-stage visitor will see high bounce rates regardless of traffic quality.

This step is about diagnosing whether what looks like a traffic problem is actually a messaging or user experience problem. Both are fixable, but they require different solutions. Fixing your targeting won't help if qualified visitors are bouncing because the landing page doesn't meet their expectations.

Step 6: Set Up Ongoing Search Term Monitoring

Here's something most guides on this topic miss: fixing low quality traffic is not a one-time task.

Google's matching behavior evolves. When you add new keywords, adjust bids, change budgets, or expand campaigns, new search terms start appearing in your report. Some of those will be irrelevant. Without a regular review cadence, the problem quietly creeps back.

The fix is simple: build search term review into your regular campaign management routine. A weekly or bi-weekly cadence works well for most accounts. If you're managing high-volume campaigns or running frequent changes, lean toward weekly. For smaller, more stable accounts, bi-weekly is usually sufficient.

Each review session should follow the same basic process:

1. Open the Search Terms Report and filter for the past 7 to 14 days.

2. Sort by cost and scan for irrelevant or low-intent queries.

3. Add irrelevant terms to your negative keyword list at the appropriate level.

4. Flag any high-intent search terms that aren't already in your keyword list as candidates to add as positive keywords.

5. Update your running negative keyword list document so you have a record of what's been added and why.

If you want to make this process faster, Keywordme is built exactly for this workflow. The Chrome extension surfaces your search terms directly inside Google Ads and lets you add negatives, promote high-intent terms to keywords, and apply match types in a few clicks — without exporting data, switching tabs, or opening a spreadsheet. For agencies managing multiple accounts, this kind of streamlined review can make a meaningful difference in how quickly you can work through each client's search terms each week.

Set a recurring calendar reminder for your review sessions, or anchor the task to something you already do regularly — like your weekly reporting check. The specific cadence matters less than the consistency.

The success indicator here is a documented, repeatable process that you actually follow. Not a plan to review search terms someday, but a scheduled habit that keeps your account clean over time.

Putting It All Together

Cutting low quality traffic in Google Ads comes down to one core habit: regularly reviewing the search terms that are actually triggering your ads and acting on what you find. The six steps above give you a complete process for doing that, from initial diagnosis through to ongoing maintenance.

Before you wrap up, run through this quick checklist:

Search Terms Report reviewed: Irrelevant and low-intent queries identified and prioritized by cost.

Match types audited: Broad match keywords assessed and adjusted where the data supports it.

Negative keywords added: Flagged search terms added at the right level (ad group, campaign, or account) with appropriate match types.

Campaign and ad group structure reviewed: Ad groups are tightly themed, and network settings reflect deliberate choices.

Landing page alignment confirmed: Pages match the intent of the search terms driving traffic to them.

Ongoing monitoring cadence set: A recurring review schedule is in place and on your calendar.

Work through these steps consistently and you'll have a cleaner, more efficient account — one where your budget is working for you instead of leaking out through irrelevant clicks.
