Competitor Analysis Tools: 15 Quick Ways to Compare Websites

By Andy Crestodina

I usually ignore the competition. Watching the other guy can be a distraction, taking my focus off of the important things like taking care of clients and sharing my best advice.

But analyzing competitor websites can quickly give you ideas for your own web marketing. Of course, you can’t see their Analytics, but there are lots of free competitor analysis tools that will give you fast and valuable insights.

Here are 15 competitive analysis tools that you can use to compare your website to the other guys in many ways: search optimization, digital advertising, social media, traffic and technology.

Here we’ll list them alphabetically, but you can see they have overlapping features. They all have free tools and more powerful paid versions. We’ve also shown how to do competitive analysis with each in the detailed descriptions below.

Let’s break down each type of analysis. They each represent different aspects of digital marketing and criteria for evaluating websites.

Keyphrases and Search Engine Rankings

What do they rank for? What battles are they winning? And are we even in those same fights?

Seeing what your competitors rank for and how high will immediately give you ideas for content and keyphrases. Without using a tool, the only way to find this information would be to search for every conceivable keyphrase.

Pay Per Click and Digital Advertising

What phrases are they bidding on? Where are they investing their ad budgets? What do their ads look like?

Similar to organic rankings, watching a competitor’s ad spending will give you insights into what might be a good investment for you. Assuming they have well-managed, well-optimized campaigns, you can see which words and phrases are getting traction with your target audience.

Authority and Link Popularity

How famous and trustworthy is their website? Are their pages more likely to rank than ours? Who can target the more competitive phrases?

The next level of SEO competitive analysis is all about links. Sites with links from many other websites have higher authority, especially if the links are from sites that have high authority themselves.

The original metric of authority is Google’s own “PageRank” but they no longer share this data. So these tools offer proxy metrics. Beyond the number, you can use these reports to find PR opportunities. If a media site or blog has mentioned and linked to a competitor, it may be a good site to pitch to yourself!

The many sources of link popularity data

There are many tools that track links and provide authority metrics. Each has its own name for the number, but they all essentially measure the same thing: the likelihood of ranking and they all use a scale from 1 – 100.

  • MOZ: Domain Authority
  • SEMrush: Domain Score
  • Alexa: Competitive Power
  • Ahrefs: Domain Rating
  • Searchmetrics: Page Strength

Social Media

Which of their articles is getting shared the most? Which of their social networks is getting the best results? Who is sharing their content?

Social accounts are easy to watch, but hard to analyze. At a glance, you can see which specific posts are getting engagement, but the big picture is impossible to see without tools.

The insights are very useful and include ideas for what to write about, where to be active and who to collaborate with.

Traffic

If their site more popular than yours? Are they getting more traffic? Are their visitors more engaged?

There are no tools that will give you an accurate look into their Analytics, but there are ways to get website traffic estimates. These tools give you a big picture, top-line look into who is getting more visitors, when they visit, demographics and behavior data.

Technology

What framework is their site built on? Is it WordPress? What tracking tools are they using?

Website technology is surprisingly visible, and there are tools that make it easy to sniff out exactly what’s powering your competitor’s website and what tools and plugins are bolted on. This gives you visibility into what tactics they’re likely using and what might work well for you.


1. SEMrush

website | rankings, advertising, authority, social media

Popular and powerful, we have to list this one first. It’s the most recommended SEO tool on Robbie Richard’s survey of top SEOs. SEMrush shows both organic and paid search rankings for any site, mobile or desktop in any country. Just drop in the URL.

Paid users can use advanced filters to find the most important phrases fast. Remove low ranking phrases, low volume phrases and branded phrases. Here’s what the filter will look like:

The paid version also includes site audits, brand tracking and more. The only downside to SEMrush is that it has so many features, it takes a while to find everything!

2. Ahrefs

website | rankings, authority

There is no free version, but you can get a 2-week free trial. Once you’re in, you’ll have access to the largest database of keyphrases of any of these analysis tools: four billion keyphrases. This is definitely a power user tool with many features beyond keyphrase tracking. Not surprising it’s #2 on Robbie’s leaderboard.

Considering targeting a phrase? Ahefs provides detailed reports with search volume, projected traffic, competition and SERP analysis.

Ahrefs also includes a lot of other reports for tracking keywords and links. These go beyond competitive analysis. These are power tools for serious SEOs. If search is critical to your company, you likely need these options.

3. Alexa

website | rankings, advertising, authority, traffic

One of the best known competitive metrics and tools for website analysis, Alexa provides a number that some marketers obsess over. The “Alexa Rank” is an estimate of the popularity and ranking of every website globally and in every country.

The paid version also has excellent tools for spying on competitors rankings.

One of our favorite reports is the “Audience Overlap Tool” which first tells you which sites you compete with, then it shows you the phrases you’re competing for. It puts everything on a table. The darker table cells show who’s winning. Amazing!

Alexa is also one of the only tools to estimate behavior data (bounce rate, time on site) and demographics (gender, education levels). No wonder people love it.

  • Paid version: $99/month

4. BuiltWith

What content management system are they using? What are they tracking? Do they use a content delivery network? What plugins are installed? Are they doing retargeting?

This fast, free analysis tool shows you everything that can be learned by analyzing the code of the website. It’s a lot of information and a bit like doing IT due diligence on a competitor. Plug in a competitor’s website and instantly see what software and systems they have plugged in. This gives you powerful tools into their marketing strategies.

It’s also easy to see what phrases that competitor website is bidding on and how those bids have changed over time.

It’s a popular and powerful SEO tool with all kinds of useful reports. The one most relevant to competitive analysis is Link Explorer. This is probably the most famous tool for measuring link popularity. They use the term “Domain Authority” for their metric.

It’s super easy to use. Just put in your site to see your Domain Authority, then put in a competitor. Or use the “Compare Link Metrics” tool. The site with the higher authority is more likely to rank for more competitive phrases.

A few notes: Domain Authority will naturally fluctuate over time. Also, keep in mind that ultimately, it’s pages that rank in Google, not domains. So the “Page Authority” of the specific pages is even more important. To better understand this tool, read How to Increase Domain Authority.

This is one of the oldest and most trusted traffic estimators. Similar to Alexa, it ranks sites globally and nationally by traffic. It also puts each website into a category and shows a category rank.

The free version is very easy to use. It only shows the top five ranking keyphrases, so it’s not ideal for SEO comparisons. But it does show the top referring websites, which is not available in any other tool.

When to do this kind of competitive analysis

These are the times when checking out the competition is especially useful:

  • When starting a web-based business
  • When starting a website redesign project
  • Twice a year or so, just because (put it on your calendar!)

There you have it. Fourteen tools to snoop on the competition. Don’t pay too much attention to the other guys, but never miss a chance to find the data that can help you make better decisions.

PS: I’ve once made the case that for content marketers, there’s no such thing as competition, only collaboration. If you think you’re competing with someone, you probably just don’t know them well enough. They likely have a different specialty, price point and target market.

What do you think?
