Keyword MSV
Monthly Search Volume (MSV) is an estimated count of how many times a keyword is searched in a month, averaged over time.

Here's what I'd do first if I were starting from scratch.
What I'd do first
- Open Google Keyword Planner (free with an Ads account) or a trial of Semrush / Ahrefs.
- Type in a few topic ideas and look at the MSV column.
- Sort by volume to see which terms get searched most.
- Cross-check with Google Trends to spot seasonality—don't trust a single average number.
- Pick 3-5 keywords with decent volume AND clear search intent (e.g., "buy running shoes" vs. "best running shoes").
Plain-English take
MSV is like a restaurant's daily customer count—but the count is an average over the last year, not today's actual number. If a keyword shows 10,000 MSV, it means roughly 10,000 people search for it each month on average. Some months might be 15,000, others 5,000. The number helps you gauge interest, but it's not a promise of traffic. Think of it as a compass, not a GPS.
When it actually matters
- Prioritizing content topics: High MSV signals demand, so you know people care about the topic.
- Estimating traffic potential: If you rank #1, you might get a fraction of that MSV as clicks (depends on CTR and SERP features).
- Comparing keyword opportunities: 1,000 MSV with low competition can be better than 10,000 MSV with fierce competition.
- Budgeting for paid search: MSV helps estimate how many impressions you could get with ads.
What I got wrong
- Treating MSV as exact: I used to think 5,000 meant exactly 5,000 searches. It's an estimate, and different tools show different numbers.
- Ignoring intent: I chased high-volume terms like "SEO" but wrote a beginner guide—people searching that wanted advanced tips. Traffic came, but bounces were brutal.
- Forgetting seasonality: I built content around "Christmas gifts" in July based on average volume. Come December, the spike was huge, but I missed the window to optimize.
- Overlooking low-volume gems: I dismissed 50 MSV keywords until one converted at 10%—way better than a 0.5% conversion on a 5,000 MSV term.
