How Do I Fix Low Impression Share in Google Ads? A Step-by-Step Guide

TL;DR: Low impression share in Google Ads usually comes down to one of three things: budget constraints, low Ad Rank, or overly restrictive targeting. This guide walks you through exactly how to diagnose the root cause and fix it, step by step.

If your ads aren't showing up as often as they should, you're leaving clicks and conversions on the table. Impression share (IS) tells you what percentage of eligible auctions your ads actually appeared in. If that number is lower than you'd like, Google even tells you why, via the "Lost IS (Budget)" and "Lost IS (Rank)" columns right inside the interface.

The tricky part isn't finding the metric. It's knowing what to do next. A lot of guides just say "increase your budget" or "improve Quality Score," which isn't wrong, but it's not a plan. This guide is a plan.

Whether you're a freelancer managing a handful of accounts or an agency running campaigns across dozens of clients, the frustration is the same: you can see IS is low, but the path from "low number" to "fixed number" isn't obvious. Do you raise bids? Restructure campaigns? Add extensions? The answer depends entirely on what's actually causing the loss, and that's what this guide will help you figure out.

We'll start with diagnosis, then move through each lever you can pull: budget, Ad Rank, keyword strategy, bids, and extensions. Each step builds on the last. Skip the diagnosis step and you'll likely fix the wrong thing, or worse, spend more budget on a campaign that still underperforms.

By the end, you'll have a repeatable process you can apply to any campaign, any account, any time IS starts slipping.

Step 1: Pull the Right Columns and Diagnose What's Actually Causing Low IS

Before you change anything, you need to know which type of impression share loss you're dealing with. Google splits this into two buckets: budget-driven loss and rank-driven loss. The fix for each is completely different, so diagnosing first saves you a lot of wasted effort.

Here's how to pull the columns you need. Go to your Campaigns view in Google Ads, click the "Columns" icon, then select "Modify columns." Under the "Competitive metrics" section, add these three columns:

Search Impression Share: The percentage of eligible auctions where your ad actually appeared.

Search Lost IS (Budget): The percentage of auctions you missed because your budget ran out.

Search Lost IS (Rank): The percentage of auctions you missed because your Ad Rank wasn't high enough to show.

Once those columns are visible, the interpretation is fairly straightforward. If Lost IS (Budget) is high, your ads are being throttled because you're hitting your daily budget cap before the day ends. If Lost IS (Rank) is high, your bids or Quality Score aren't competitive enough to win the auction. In some cases, both will be elevated, which means you have layered problems to work through.

In most accounts I audit, people look at IS at the account level and try to make sense of it from there. That's the wrong starting point. You need to segment down. Look at IS by campaign first, then drill into ad groups, and then into individual keywords. A single underperforming campaign with a large budget can drag your overall IS number down significantly while other campaigns are running just fine.

A practical move here: sort your campaigns by Lost IS (Rank) descending. This surfaces the campaigns where quality issues are costing you the most auctions. Those are your highest-priority targets for the steps that follow.

Also worth noting: impression share data is available at the campaign, ad group, and keyword level, but not all three columns are available at every level. At the keyword level, you'll see Quality Score alongside IS data, which is exactly where you want to be when diagnosing rank-driven losses.

The common mistake here is jumping straight to "let's raise the budget" without checking whether Lost IS (Rank) is actually the bigger problem. If rank is the issue and you just add budget, you'll spend more money showing in the same mediocre positions. Diagnose first, then act.

Step 2: Fix Budget-Driven Impression Share Loss First

If Lost IS (Budget) is your primary culprit, your ads are literally being turned off mid-day because your daily budget cap has been hit. Google will show you this directly: look for campaigns with a "Limited by budget" status tag next to the campaign name. That's your confirmation.

There are three practical ways to address this, and which one makes sense depends on your account structure and what you're willing to spend.

Option 1: Increase the daily budget. The most direct fix. If a campaign is consistently hitting its cap and the keywords are performing well, the math is simple: more budget means more auctions entered, which means higher IS. Before you do this, make sure the campaign is actually converting efficiently. Throwing budget at a campaign with poor conversion rates just scales the waste.

Option 2: Consolidate campaigns to pool budget more efficiently. If you have multiple campaigns targeting similar audiences or themes, consolidating them lets a single budget stretch further. Fragmented campaign structures often mean some campaigns run out of budget early while others barely spend. Consolidation fixes the distribution problem.

Option 3: Use shared budgets strategically. Google Ads allows multiple campaigns to draw from a single shared budget pool. This is particularly useful when you have campaigns with variable daily spend patterns. A campaign that spends heavily on weekdays can "borrow" from a campaign that's slower on those days. It's not a fix for insufficient total budget, but it's a useful tool for redistribution.

To think through the right budget level, work backward from your target IS. If you know your average CPC and roughly how many auctions you're missing due to budget, you can estimate how much additional daily spend would close the gap. You don't need a formula for this; Google's budget recommendation tool inside the interface will often suggest a number, and it's worth at least reviewing what they're projecting.

One important warning: don't increase budget before you've checked whether quality issues are also present. If Lost IS (Rank) is also elevated, increasing budget without fixing quality means you're paying more to show in worse positions on underperforming keywords. Fix quality issues in parallel, or address rank-driven losses first.

Step 3: Improve Ad Rank to Recover IS (Rank) Losses

Ad Rank is the score Google uses to determine whether your ad shows and in what position. It's calculated using your bid, your Quality Score components (expected CTR, ad relevance, and landing page experience), auction-time signals like the user's device and location, and the expected impact of your ad assets. You can't see your actual Ad Rank number, but you can see the Quality Score it's built on.

To find low Quality Score keywords, go to the Keywords tab, add the Quality Score column, and sort ascending. Keywords scoring 3 or below are actively hurting your IS. For each low-scoring keyword, check the three sub-components: Expected CTR, Ad Relevance, and Landing Page Experience. Each one will show as "Below average," "Average," or "Above average," which tells you exactly where to focus.

Fixing Expected CTR: This usually comes down to ad group structure. If you're running loosely themed ad groups where one set of ads has to serve a wide range of keywords, your ads won't feel specific enough to earn clicks. Tighten your ad groups so each one covers a narrow theme. When ads match the search intent closely, CTR improves, and Google's expected CTR estimate follows over time.

Fixing Ad Relevance: The most direct lever here is including the keyword or a close variant in your headline. If someone searches "emergency plumber London" and your headline says "Fast Local Plumbing Services," that's a relevance gap. A headline like "Emergency Plumber in London" closes it immediately. This sounds obvious, but in most accounts I audit, there are ad groups where the headline doesn't reflect the core keyword at all.

Fixing Landing Page Experience: Google evaluates whether the page the ad sends users to actually matches what the ad promised. A few things to check: Does the page content align with the keyword intent? Does it load quickly on mobile? Is it easy to navigate? A high-intent keyword landing on a generic homepage is a common landing page experience killer. Create dedicated landing pages for your top keyword themes where possible.

One realistic expectation to set here: Quality Score changes take time to reflect in the interface. Google updates it based on recent auction performance, so improvements you make today may take days or weeks to show up in the column. Don't make changes and expect overnight results. Make the changes, give it two to three weeks, and then reassess.

Step 4: Tighten Your Keyword Strategy to Win More Relevant Auctions

Here's something counterintuitive about impression share: you can have high impression share on auctions you don't actually want. Broad match keywords can trigger your ads across a huge range of loosely related searches, technically "winning" those impressions while burning budget on queries that will never convert. Your IS number might look acceptable, but the quality of those impressions is poor.

The fix starts with match types. Broad match spreads your budget across a wide net. Phrase match and exact match concentrate spend on higher-intent, more predictable queries. If you're running broad match across your entire campaign and wondering why IS on your core terms feels low, the answer is often that your budget is being spread thin across dozens of irrelevant auctions.

This is where the search terms report becomes your most important diagnostic tool. Pull it regularly and look for patterns: queries that have nothing to do with your product, informational searches from users who aren't buyers, competitor brand terms you didn't intend to target, and geographic queries that don't match your service area. Every one of those is a wasted impression that dilutes your IS efficiency on the terms that actually matter.

The practical workflow looks like this:

1. Review your search terms report weekly, not monthly. The longer you wait, the more budget has been spent on off-target queries.

2. Add negatives for anything clearly irrelevant. Build out your negative keyword list at the campaign and ad group level systematically.

3. Identify high-performing search terms that are currently triggering via broad or phrase match, and add them as exact match keywords. This gives you more control over bidding and reporting on those specific terms.

4. Consolidate or pause keywords that are generating impressions but no conversions over a meaningful time window. They're diluting your IS without contributing value.

What usually happens in accounts that skip this step is that the search terms report is reviewed quarterly at best, negatives are sparse, and budget is quietly leaking to irrelevant queries month after month. It's one of the highest-ROI maintenance tasks in PPC, and it's also one of the most time-consuming when done manually.

This is exactly where a tool like Keywordme earns its place in the workflow. Instead of exporting search terms to a spreadsheet, cross-referencing with your keyword list, and then manually uploading changes, you can add negatives and apply match type changes with a single click directly inside the Google Ads search terms report. For agency teams managing multiple client accounts, that kind of time compression adds up fast.

Step 5: Adjust Bids Strategically—Don't Just Raise Everything

Bid amount directly influences Ad Rank, which directly influences whether your ad shows at all. If Lost IS (Rank) is high and your Quality Score is already solid, raising bids on the right keywords is a legitimate fix. The key word is "right."

Start at the keyword level. Sort your keywords by Lost IS (Rank) descending to find the specific terms where rank is costing you the most auctions. Those are the candidates for bid increases. Keywords that are already winning efficiently at a lower CPC don't need higher bids; increasing them there just raises your costs without meaningful IS gains.

On the bidding strategy side, Google offers a Smart Bidding option called Target Impression Share. You set a target IS goal (for example, 80% at the top of the page) and Google automatically adjusts bids across auctions to hit that target. It's useful when IS is the primary goal and you're comfortable letting Google control bid-level decisions. The tradeoff is that you lose granular manual control, and Google will sometimes bid up aggressively on auctions that don't convert well. Use it with a clear maximum CPC cap to prevent runaway spend.

Bid adjustments by segment are another underused lever. If your conversion data shows that mobile users convert at a much lower rate, applying a negative bid adjustment for mobile concentrates your budget on the device segments where you actually win business. The same logic applies to location and time of day. Concentrating budget on high-converting segments improves your effective IS where it counts, even if your overall IS number doesn't change dramatically.

The mistake most agencies make here is treating bid increases as a default fix for any IS problem. If Quality Score is below average, raising bids means you're paying more for the same mediocre position. Fix quality first when possible, then use bids to amplify the improvement.

Step 6: Use Ad Extensions to Boost Ad Rank Without Changing Bids

Ad extensions, now called "assets" in the Google Ads interface, are one of the most underutilized levers for improving Ad Rank. Google explicitly includes the expected impact of your assets as a component of Ad Rank. More relevant assets mean a higher expected CTR, which improves your rank without requiring you to increase your bid.

Think about it from the user's perspective. An ad with four sitelinks, two callouts, and a structured snippet takes up significantly more real estate on the search results page. It looks more credible, offers more paths to click, and signals that the advertiser has put real effort into the ad. Compared to a bare-bones ad with just a headline and description, it will almost always win more auctions at the same bid level.

To audit your current asset usage, go to the Assets tab in Google Ads and check which asset types are active at the campaign and account level. Pay particular attention to these four:

Sitelinks: Aim for at least four active sitelinks per campaign. They should link to genuinely useful pages, not just variations of the homepage.

Callouts: Short phrases that highlight real USPs. "Free shipping," "24/7 support," "No contracts" are the kind of specifics that improve CTR.

Structured snippets: Use these to list services, product types, or features. They give users a preview of what you offer before they click.

Call extensions: If phone calls are a conversion type for you, this is a no-brainer. They also contribute to Ad Rank through expected CTR.

A campaign with no assets competing against a competitor running six sitelinks, callouts, and structured snippets will often lose the auction even at a similar bid. Assets are free to add and they directly improve your competitive position. If your campaigns are missing them, fixing that is one of the fastest IS wins available.

Putting It All Together: Your IS Recovery Checklist

Improving impression share isn't a one-time fix. It's a diagnostic process you run repeatedly as campaigns evolve, competition changes, and budgets shift. The accounts that maintain strong IS over time are the ones that treat it as a regular checkpoint, not a one-off project.

Here's the checklist to run through whenever IS drops or you're starting an audit:

Diagnose first: Add Search IS, Lost IS (Budget), and Lost IS (Rank) columns. Identify whether the loss is budget-driven or rank-driven before touching anything.

Fix budget constraints: Check for "Limited by budget" tags. Increase daily budgets, consolidate campaigns, or implement shared budgets where appropriate. Don't increase budget on campaigns with quality problems.

Improve Quality Score: At the keyword level, sort by Quality Score ascending. Address expected CTR through tighter ad group theming, ad relevance through headline alignment, and landing page experience through intent-matched pages.

Tighten keyword strategy: Review the search terms report weekly. Add negatives for irrelevant queries. Move high-performing search terms to exact match for better control.

Adjust bids strategically: Raise bids on keywords with high Lost IS (Rank) where quality is already solid. Use bid adjustments by device, location, and time to concentrate spend where it converts.

Add missing assets: Audit the Assets tab. Ensure every campaign has at least four sitelinks, active callouts, and relevant structured snippets.

Check these metrics weekly, not daily. Daily fluctuations are normal. Weekly trends are where the signal lives.

If you're managing IS across multiple campaigns or client accounts, the manual overhead adds up quickly, especially the search terms review and negative keyword work in Steps 4 and 5.
