The world of search engine optimization (SEO) and digital marketing is littered with metrics. One of the biggest metrics, however, is monthly search volume (MSV). This is the estimated number of times a specific word or phrase is searched for in a search engine in any given month.
Some MSV data comes directly from search giants. For example, Google offers Keyword Planner as part of its Google Ads platform, and it allows you to enter different terms to research their MSVs. Other popular tools for checking MSV keywords include Ahrefs, SEMrush, Moz, and Keywords Everywhere, though it’s worth noting that each tool pulls from different data sources, so results can vary by 20–40%. Notably, the MSV figure is almost always an estimate and not an exact number, with the math factoring in both historical search volume data and algorithmic data.
As a general framework, MSV keywords fall into three ranges:
- High MSV keywords: 10,000+ searches per month (e.g., “running shoes” at ~50,000 MSV)
- Medium MSV keywords: 1,000–10,000 searches per month
- Low MSV keywords: Under 1,000 searches per month (e.g., “best trail running shoes for women” at ~800 MSV)
These ranges aren’t rigid rules, but they give you a working baseline when evaluating search traffic potential and planning your keyword strategy.

Why Care about MSV?
People care because MSV is a good proxy for a topic’s popularity and overall audience interest. Looking at broad MSV estimates gives you a good sense of the potential organic traffic and organic growth that might accompany targeting a particular keyword or phrase. It also gives you a good way to perform competitive analysis since you can follow up with your own keyword searches and see who appears on the first page. Especially if you’re building a content-centric content strategy, MSV will guide your choices in terms of targeting MSV keywords and how to structure on-page content.
The Problem with Relying Solely on MSV (Monthly Search Volume)
User Intent
User intent and MSVs can diverge significantly. You will see gigantic MSVs for the term “iPhone,” for example. “iPhone” doesn’t tell you much about the user’s intent, however. Plenty of people will search for everything from iPhone user guides to repair shops. Conversely, a search like “where to buy an iPhone 17 online” is loaded with user intent. The latter is far more valuable to businesses because it’s tied directly to purchase intent.
The reason you care is that volume doesn’t necessarily translate into conversions or a high click-through rate. High MSV keywords might drive large amounts of search traffic, but you may get more conversions from low MSV keywords that are rich with intent. A term like “best trail running shoes for women” converts at a far higher rate than “running shoes” despite a fraction of the volume.
Ranking Difficulty and Competitiveness
High MSV keywords, often synonymous with high search volume keywords, tend to carry extreme competitiveness. If you try to rank #1 for “Nintendo Switch 2,” you will aim for a high MSV keyword. However, the competitiveness in that segment means every major electronics retailer on Earth has also come to fight.
It takes significant resources, time, and domain authority to even hold up in that battle, let alone win. Small businesses typically can’t compete with large enterprises on high MSV keywords where competitiveness is already saturated. That’s often where low MSV keywords become a smarter investment, offering less competitiveness, more specific intent, and a realistic path to page one.
Data Limitations
Every search tool will show different figures for various MSV keywords. You can easily see a discrepancy of 20–40% in MSV and even CTR between tools like SEMrush and Google Keyword Planner. Seasonal fluctuations also affect data. A keyword like “snowblower” will spike in November and flatline in June, making its annualized MSV misleading if you don’t check the trend.
Geographic variation matters too. An MSV keyword showing 10,000 monthly searches globally might only pull 500 in Canada. Always specify your target country or region when researching MSV keywords, and cross-reference with Google Trends to spot seasonal patterns and regional demand.
How to Check MSV Keywords: A Best-Practice Walkthrough
If you’re new to keyword research, here’s a simple process for evaluating MSV keywords using a keyword research tool:
- Start with a seed keyword. Enter a broad topic into a tool like Google Keyword Planner, Ahrefs, or SEMrush.
- Review the MSV data. Note whether the keyword falls into the high, medium, or low MSV range.
- Check competitiveness. Look at the keyword difficulty score and review who currently ranks on page one.
- Evaluate intent. Ask whether the keyword signals awareness, consideration, or decision-stage intent.
- Filter by geography and trends. Narrow results to your target region and check for seasonal patterns that could skew the MSV.
- Compare across tools. Cross-reference at least two sources, since MSV estimates can differ significantly between platforms.
This process helps you move beyond raw search traffic numbers and toward keywords that actually align with your goals.
How Search Behavior and SEO Are Evolving
Modern search users are becoming more conversational and specific in their tone. The net effect is that their queries are frequently longer and more detailed. Voice search especially encourages this type of long and natural query.
The consequence is that better conversion rates tend to appear for low MSV keywords. After all, the difference in user intent for “BMW” versus “BMW mechanic near me” is pretty dramatic, even if the MSV for “BMW” is in the millions monthly. The user intent will show up as greater conversions for mechanic searches because the need is much more specific.
The net effect is that topic clusters are more important than winning the ranking battle for a single high MSV keyword. Related terms will still rank well on search engine results pages. Content as part of an SEO strategy needs to account for which search stage a user is at, be it awareness, consideration, or decision.
Search providers know this, and their algorithms have de-emphasized the importance of MSV. Semantic relationships and user intent will cause some seemingly specific search results to appear on results pages that don’t use the exact phrase from an MSV keyword.
When MSV Still Matters
MSV remains a strong indication of brand awareness. It also shows where there are opportunities for producing educational content. If you have broad visibility goals, particularly improving awareness at a brand’s early stages, targeting high MSV keywords still matters.
You also should consider fighting for high MSV keywords if you have:
- Strong domain authority
- A serious budget
- Solid content support
Pair MSV with other metrics, such as keyword difficulty, competitiveness, opportunity, and user intent. This will help you better match your efforts to potential conversions rather than chasing search traffic alone.
Best Practices for MSV Analysis
Effective MSV analysis is about balancing search traffic potential against competitiveness and intent. A few practices worth building into your workflow:
Lead with keyword intent and relevance, not raw search traffic. A high MSV keyword that doesn’t match your offer wastes budget.
Hunt for low MSV keywords with minimal competitiveness. These long-tail opportunities are often goldmines for conversions because intent is sharper and ranking is realistic.
Build topic clusters rather than chasing a single high MSV keyword. Collectively, low MSV keywords in a cluster can outperform a single high MSV keyword while facing far less competitiveness.
Audit your MSV keywords quarterly. Search traffic patterns shift, competitiveness changes as new entrants arrive, and what was a viable high MSV keyword target last year may now be locked up.
Measure conversions, engagement, and search traffic flow alongside MSV, not just rankings.
Common Challenges in MSV Analysis
The biggest challenge is misjudging competitiveness. Tools report MSV keywords with difficulty scores, but those scores rarely capture the full picture of domain authority, content depth, and backlinks held by sites already ranking. A high MSV keyword that looks moderately competitive on paper is often locked up in practice.
Another challenge is over-indexing on search traffic at the expense of intent. A high MSV keyword can pull large amounts of search traffic that never converts, while a cluster of low MSV keywords with sharper intent quietly drives revenue.
Data inconsistency is the third recurring issue. As noted earlier, MSV figures vary 20–40% between tools, so cross-reference at least two sources before committing budget to any MSV keyword.

How reliable is MSV data when evaluating keyword competitiveness?
Should I prioritize search traffic volume or keyword intent?
Conclusion
MSV alone is not enough. Search is changing rapidly, and algorithms are too sophisticated to prioritize exact matches. Likewise, searchers are increasingly focused on highly conversational long-tail keywords, which often fall into the low MSV keyword range. You must reinforce SEO with a balanced keyword strategy that accounts for metrics like user intent, competitiveness, and conversions rather than chasing high MSV keywords and raw search traffic alone.
