The Google Ads Keyword Planner gives you a column-heavy interface that most small business owners open once, feel overwhelmed by, and never return to. That interface — with its keyword, currency, avg. monthly searches, three month change, yoy change, competition, competition (indexed value), top of page bid (low range), top of page bid (high range), ad impression share, organic impression share, organic average position, in account, in plan, and searches data — is actually one of the most useful free research resources available to any advertiser running paid search.
This article explains what every column in the Google Ads Keyword Planner actually means, how to use the data to make smarter bidding and budgeting decisions, and where human interpretation still matters more than any automated output.
What the Keyword Planner Data Columns Actually Mean
The keyword, currency, avg. monthly searches, three month change, yoy change, competition, competition (indexed value), top of page bid (low range), top of page bid (high range), ad impression share, organic impression share, organic average position, in account, in plan, and searches columns are not decorative. Each one answers a specific operational question about whether a keyword is worth targeting, what it will cost, and how you are currently positioned against it.
Start with avg. monthly searches. Google presents this as a range rather than an exact figure — you might see 1,000–10,000 for a given term. This is intentional. Google does not expose precise search volumes to prevent advertisers from reverse-engineering competitive intelligence. The range is directionally useful, not mathematically precise. If you are comparing two keywords and one sits in the 100–1,000 bracket while another sits in the 10,000–100,000 bracket, that distinction matters far more than trying to pin down an exact number.
The three month change and yoy change columns show trend direction. A keyword with 10,000 monthly searches and a negative yoy change is declining — that context changes how aggressively you should invest in it. We ran a marketing agency for nine years, and one of the most consistent mistakes we saw was businesses bidding heavily on terms that looked healthy by volume alone but were quietly losing relevance. Trend data prevents that mistake.
Understanding Competition and Indexed Value
The competition column in Keyword Planner — low, medium, or high — reflects the number of advertisers bidding on a keyword relative to all keywords in Google Ads. It is not the same as search difficulty in an SEO context. A keyword can be low competition in paid search and still have a highly competitive organic results page.
The competition (indexed value) column translates that categorical label into a numerical score from 0 to 100. This is more useful when comparing similar keywords. If two terms both show as "medium" competition but one scores 45 and the other scores 72, the latter is meaningfully harder to compete in. Use the indexed value when you need to rank a list of potential keywords by competitive intensity rather than simply filtering by the broad label.
For a fuller picture of how paid and organic competition interact, AdWords Keywords: What SMEs Actually Need to Know covers the strategic side of keyword selection in more detail.
Top of Page Bid Ranges: What They Tell You
The top of page bid (low range) and top of page bid (high range) columns represent the lower and upper end of what advertisers have historically paid to appear at the top of the search results page for that keyword. These are not guaranteed costs — your actual CPC will depend on your Quality Score, landing page relevance, and auction dynamics at the moment your ad enters a live auction.
Think of the range as a bracket. If the low range is £0.80 and the high range is £4.20, you are looking at a keyword where cost-per-click varies significantly based on how well your account is set up. A poorly structured campaign with a weak landing page will pay towards the top end of that range. A tightly built campaign with strong relevance signals will pay closer to the bottom. This is why bid management is not purely a numbers exercise — the quality of your account infrastructure directly affects what you actually spend.
For context on what SMEs typically pay across different keyword categories, Ad Cost on Google: What SMEs Actually Pay breaks down realistic cost expectations by industry.
| Column | What It Measures | Practical Use |
|---|---|---|
| Avg. monthly searches | Estimated search volume (range) | Assess demand size |
| Three month change | Short-term trend | Spot seasonal shifts |
| YoY change | Annual trend | Identify growing or declining terms |
| Competition (indexed value) | Advertiser competition 0–100 | Compare similar keywords precisely |
| Top of page bid (low range) | Lower historical CPC benchmark | Set minimum budget expectations |
| Top of page bid (high range) | Upper historical CPC benchmark | Identify costly keyword categories |
| Ad impression share | Your ads' share of eligible impressions | Spot budget or bid gaps |
| Organic impression share | Your organic presence for the term | Find paid/organic overlap |
| Organic average position | Average organic ranking | Prioritise where organic is weak |
| In account | Keyword already in your account | Avoid duplication, spot gaps |
| In plan | Keyword added to your plan | Track research selections |
Ad Impression Share and Organic Impression Share
Ad impression share tells you what percentage of auctions your ads appeared in for a given keyword, out of all the auctions you were eligible to enter. If you have a keyword in your account with an ad impression share of 30 per cent, you are missing 70 per cent of potential appearances — either because your budget runs out, your bids are too low, or your Quality Score is limiting eligibility.
Organic impression share shows how often your website appears in the organic results for that same keyword. This column only populates if you have connected your Google Search Console account to Google Ads. When it does appear, it creates a genuinely useful paired view: you can see where you are showing in both paid and organic simultaneously, and where you are absent in one or both. If your organic impression share is high for a term but your ad impression share is low, you might choose to redirect that ad budget to terms where your organic presence is weaker.
The organic average position column completes this picture by showing your typical ranking in the organic results. A position of 1–3 is strong. Positions 8–15 represent the borderline of page one visibility. If you are sitting at position 12 organically for a high-value keyword, running paid ads for that term while you work on organic rankings is a rational short-term approach.
Paid Search Optimisation: What Actually Moves the Needle covers how to use impression share data to prioritise where you allocate budget.
In Account and In Plan: The Operational Columns
The in account and in plan columns are administrative rather than analytical. "In account" indicates that the keyword already exists somewhere in your Google Ads account. "In plan" shows that you have added the keyword to the plan you are currently building in Keyword Planner.
These columns matter most when you are doing a keyword audit or expanding an existing campaign. If a keyword shows as already being in account, you can check whether it is in the right match type, whether it is in a relevant ad group, and whether it is active or paused. It prevents you from accidentally duplicating keywords across campaigns, which creates internal auction competition — your own campaigns bidding against each other for the same term.
For SMEs managing accounts without a dedicated paid search specialist, this kind of structural oversight is easy to miss. Small Business PPC Management: What Actually Works covers the account hygiene basics that keep campaigns running efficiently.
How Overtime Uses This Data in Practice
Reading Keyword Planner data is one thing. Acting on it correctly — and doing so consistently across campaigns — is a separate skill. The keyword, currency, avg. monthly searches, three month change, yoy change, competition, competition (indexed value), top of page bid (low range), top of page bid (high range), ad impression share, organic impression share, organic average position, in account, in plan, and searches data only creates value when it drives actual account decisions: pausing underperforming keywords, adjusting bids based on competition indexed scores, reallocating budget from saturated terms to those with stronger growth trends.
This is the operational layer where most SME accounts fall short — not because the data is unavailable, but because the time and attention required to act on it consistently is not there. Overtime is an AI agent built specifically for this problem. It logs into Google Ads accounts directly, reads performance data, adjusts bids, pauses underperformers, reallocates budget across campaigns, and sends plain-English summaries of what it has done and why.
In 2026, the gap between SMEs who actively manage their accounts and those who set campaigns live and leave them is growing. The keyword data tells you where the opportunity is. Acting on it at the right cadence is what determines whether that opportunity converts into revenue.
For SMEs who are still figuring out whether paid search is the right channel at all, What Is Paid Search: The SME Guide is a useful starting point before going deeper into Keyword Planner analysis.
Limitations Worth Knowing
Keyword Planner is a planning tool, not a forecasting engine. The search volume ranges it provides are estimates derived from historical data, and they can be meaningfully inaccurate for niche or highly specific terms. We have seen Keyword Planner show low search volume for terms that were actually driving significant traffic in live accounts — the tool under-indexes for long-tail specificity.
The top of page bid ranges also reflect historical auction data, not real-time pricing. If a competitor enters your market aggressively or a seasonal surge increases demand, actual CPCs can exceed the high range figure within days. Never treat the bid range as a fixed budget ceiling.
Finally, the organic impression share and organic average position columns only appear if Search Console is connected and your site has sufficient organic data. For newer websites or businesses in highly niche categories, these columns may simply be empty — which is not a tool failure, it is a data availability issue.
How to Fix High Cost Per Acquisition in Google Ads addresses what to do when keyword data looks healthy but campaign costs are not matching expectations.
Before diving deeper into keyword strategy, the keyword, currency, avg. monthly searches, three month change, yoy change, competition, competition (indexed value), top of page bid (low range), top of page bid (high range), ad impression share, organic impression share, organic average position, in account, in plan, and searches data should be treated as a starting point for decisions — not a substitute for them. Understanding each column removes the guesswork from keyword selection. Combining that understanding with consistent account management is where the actual return on ad spend comes from.

Frequently Asked Questions
What does competition (indexed value) mean in Google Keyword Planner?
The competition (indexed value) is a numerical score from 0 to 100 that represents how many advertisers are bidding on a keyword relative to all keywords tracked in Google Ads. A higher score means more advertiser competition. It is more precise than the categorical low, medium, or high label and is useful when comparing keywords within the same niche.
How should SMEs use top of page bid data when planning a campaign?
Use the top of page bid (low range) and top of page bid (high range) as a bracket for expected cost-per-click rather than a fixed price. Your actual CPC will depend on your Quality Score and landing page relevance. A well-structured account typically pays closer to the low range; a poorly optimised one will pay towards the high range or above it.
What is the difference between ad impression share and organic impression share in Keyword Planner?
Ad impression share shows what percentage of eligible paid auctions your ads appeared in for a given keyword. Organic impression share shows how often your website appeared in the organic results for the same term. Comparing both helps you identify where you have strong organic coverage and can reduce paid spend, and where you have gaps in both channels.
Why does Keyword Planner show search volumes as ranges rather than exact numbers?
Google intentionally presents avg. monthly searches as ranges to limit the precision of competitive intelligence available to advertisers. The ranges are directionally accurate — useful for comparing the relative size of demand between keywords — but they should not be treated as exact figures, particularly for low-volume or niche search terms.
Do I need to connect Search Console to see organic data in Keyword Planner?
Yes. The organic impression share and organic average position columns only populate when your Google Ads account is linked to a verified Google Search Console property. Without that connection, those columns will be empty. Linking both accounts takes a few minutes and unlocks a genuinely useful paid and organic comparison view. You can find setup instructions on Google's official support documentation.
