Here is a heretical opinion I have developed over the last few years: your own Google Analytics data is probably the least useful dataset you have for planning SEO strategy. The most useful one is your competitors' content calendar, and almost no one monitors it systematically.
This is going to be a shorter post than my last few, because the point is pretty simple. But I want to make it strongly, because I think most SEO teams are drowning in internal data and starving for external data, and they have it backwards.
The asymmetry of information
When you look at your own analytics, you are looking at lagging indicators. Traffic came in last week. Rankings shifted last month. A page started or stopped performing. All true. All in the past. All the result of decisions made six months ago.
When you look at a competitor's content — specifically, their recent content, the pieces they've published in the last quarter — you are looking at their strategic bets on what will perform in the next six months. If a competitor has suddenly published six pieces on a topic they didn't cover last year, they believe that topic is worth covering. They have reasons. Some of those reasons might be wrong, but some of them are right, and you can often tell which is which from the details.
Your analytics is a mirror. Competitor analysis is a map.
What to actually track
The specific things I monitor on competitor sites, in rough order of value:
Their publishing cadence. How many posts per week? Per month? Is it increasing, stable, or decreasing? A competitor ramping publishing is a competitor investing; a competitor cutting publishing is a competitor retreating. Both matter.
The topics they're entering. Specifically, topics they weren't covering a year ago and are covering now. These are the bets. If three of your competitors all entered the same topic in the last quarter, something is happening there — a search trend, a product-category shift, an emerging customer need — and you probably want to be in it too.
The topics they're abandoning. Almost as useful. If a competitor had a pillar page on "Topic X" for three years and has stopped updating it, they've decided Topic X isn't worth the investment anymore. Maybe they're right. Maybe they're wrong and you can take over the space.
Their internal linking evolution. When you visit their old pillar pages, are they still being linked to from new content? This is a surprisingly strong signal of which topics are still strategic for them.
The formats they're experimenting with. Long guides? Short listicles? Interactive tools? Comparison tables? Formats go in and out of effectiveness as SERPs evolve. Watching what your competitors experiment with saves you from running experiments that are already de-risked.
Their structured data. Check the schema.org markup on their pages. If they're suddenly using HowTo or FAQ schema where they weren't before, they've noticed it's being rewarded in the SERPs. Steal that.
The tools question
People always ask what tools to use for this. Honestly, a lot of it can be done with a browser and ten minutes a week.
Subscribe to your competitors' RSS feeds. Most blogs still publish them, even if they're buried. Your RSS reader will show you every piece they publish, in chronological order, for free.
Once a month, scan the feeds. Look for topic shifts. Click into pieces that look strategically significant and read them — don't just look at the titles. The structure and angle of a piece tells you things the title won't.
Once a quarter, do a full gap analysis (I wrote a whole piece on this). That gives you the systematic view of keyword coverage overlaps. The monthly feed-reading gives you the early signal. They're complementary.
Tools like Ahrefs and Semrush can alert you when competitors gain or lose significant rankings. These alerts are noisy. Most of them are not actionable. But scan them; occasionally there's a signal worth chasing.
VectraSEO's competitor analysis surfaces the keyword-gap view continuously. I'm biased, but I'll say: the continuous version is meaningfully better than the quarterly version, because content calendars compound and you want to see the gaps emerge as they open, not three months late.
Reading between the lines
A specific skill that separates junior and senior SEO people: reading competitor content for what it implies about their strategy, not just what it says.
When a competitor publishes a 4000-word guide on a topic, they didn't invest that effort for a 100-search-volume keyword. They think the keyword has more value than the volume suggests — probably commercial intent, or a position in a buying-journey they care about. Worth a second look.
When a competitor publishes three pieces on adjacent subtopics in a month, they're building a cluster. Clusters take six months to show returns. They're investing ahead of a strategic push.
When a competitor's recent pieces have gotten shorter and more numerous, they've shifted from depth to breadth. This is often a response to pressure from leadership for faster content throughput, and it's not always a winning strategy.
When a competitor's old pillar page suddenly gets a big refresh — new sections, updated stats, new examples — they've decided that page is worth re-investing in. Either because it's still ranking and they want to defend it, or because it dropped and they're trying to recover. Either way, the topic is live.
None of this shows up in your own analytics. It shows up only if you're watching competitors directly.
The analytics trap
I want to explain why I think teams over-rely on their own analytics. Partly, it's because the data is visible — you paid for it, you built dashboards, it's right there, why not use it? Partly, it's because internal metrics feel more "objective" than looking at other people's work. And partly, it's because analytics is measurable in ways competitor intelligence isn't — you can report "traffic up 12%" but you can't report "learned something about competitor X."
All of this is understandable. It's also a trap. Internal analytics measures the results of past decisions. You cannot make new decisions from it except defensively — "this page is dropping, should we refresh it?" That's reactive. Competitor intelligence gives you proactive information: "this topic is about to matter; get ahead of it."
The ratio of time I spend on internal analytics vs. competitor analysis is about 20/80. That's unusual. Most SEO teams I've met are at 80/20 the other way. I think they're leaving strategy on the table.
The ethical footnote
Watching competitors is not industrial espionage. It is reading their public content. Everything I've described uses information the competitor has already made public. If you're tempted to go further — scraping their private dashboards, accessing their internal systems, that kind of thing — you're in a different and wrong place. Stop.
The useful line is: treat every competitor's public content as a signal, not a target. You are not trying to copy them. You are trying to learn what they've learned, so you can make your own decisions informed by their evidence.
Do that systematically. Do it monthly. Take notes. Over a year, you will accumulate a much better model of your competitive landscape than most teams ever do. And that model will show up in better strategic calls — which topics to enter, which formats to experiment with, which pillar pages to build.
Close your analytics tab. Open your competitors'. Spend the next hour reading. See what you find.
