SEMrush and SimilarWeb are both great tools for marketers, and at least the most popular of all. Without access to credible tools, like website traffic analyzers and competitor research, digital marketers and bloggers could have difficulty planning their campaigns. But with tools like SEMrush and Similarweb, your work becomes easier. These tools enable you to access information that would otherwise be impossible to get your hands on as a digital marketer.
With any of the two, you can estimate a website’s traffic at any moment. But these tools don’t come cheap. You must pay for each. Because of this, it wouldn’t make sense to pay for the two when there’s maybe one that offers more than the other. That’s why we’re going to help you decipher in our SEMrush vs Similarweb comparison.
SEMrush vs Similarweb, Which One Should You Pick?
We’re going to look at the two, Similarweb vs SEMrush, head-to-head to help you make a more informed decision on which one to go for. Also, you can get to know which one offers more value for your money in the process. And which tool between the two is best suited for your specific needs.
SEMrush vs Similarweb Features
Features are what determine the value you get in return for your cash. Here’s a breakdown of the features offered by the two.
SEMRush features a whole host of tools beyond just SEO including tools to help with content marketing, competitor research, PPC, and social media marketing. SimilarWeb mostly just has tools to show basic web analytics including overall traffic and traffic channels. While SimilarWeb does offer some additional tools with the paid account, they still focus on traffic analysis.
Source of Data
Similarweb obtains its data from a variety of sources. The platform leverages data directly from website owners, partners, and public data sources that use proprietary technology for scanning, and anonymous behavioral data from its contributory network. All of this put together, Similarweb tries to leverage each data source’s strength to get the most accurate result.
On the other hand, SEMrush gathers data using its machine learning algorithms and data from third-party providers. It also uses different approaches of data collection, depending on the data types and corresponding databases. Because the two use different methodologies in gathering data, it makes sense to know which tool is more accurate than the other. We’ll get to that later.
Traffic Source Analysis
When it comes to traffic source analysis, both SEMrush and Similarweb offer the same data. You can access an estimate of traffic on any individual website and the various sources of traffic whether it’s from organic search, direct, referral traffic from other websites, paid search, and traffic obtained from social media channels.
SEMrush traffic analysis tool also offers you a little bit more information on a website’s traffic journey or how it generates its traffic. It also breaks down referral traffic, detailing which sources contributed to how much traffic on a specific website page on a domain. You can view traffic to a website’s subdomain.
Traffic Estimation Accuracy
These tools’ accuracy could easily be put into question since they don’t entirely rely on data provided by individual websites. Instead, they rely on a variety of sources, as mentioned above. But how accurate is Similarweb or SEMrush? This case study from OWOX should give you an insight into this critical aspect in the Similarweb vs SEMrush battle. According to the study, which analyzed SEMrush and Similarweb on 787 websites using Google Analytics data as a benchmark, the accuracy varies. Traffic data from Similarweb was found with higher deviation and did not represent Google Analytics data.
But for Similarweb, it wasn’t straightforward. Traffic data on high-volume websites (with over 1 million-plus sessions) was more accurate, but websites with at least 100k in traffic showed up to a 45% deviation from Google Analytics data. The study also reveals Similarweb having more accuracy in analyzing data from websites with at least 500k traffic, 9 to 12% more accurate than SEMrush. Similarweb also has higher accuracy analyzing website traffic on low traffic sites than SEMrush, although both exhibited “large inaccuracies” according to the report.
As a marketer or a blogger, keep your expectations in check when doing competitor analysis on sites with low traffic using either tool. And this extends to even high-traffic sites with over a million sessions in a month. From these numbers, it’s clear that every tool has its weaknesses and strengths on accuracy since they use different tools and methodologies for collecting and analyzing data. In summary, overall, SEMrush and Similarweb have similar accuracy according to the report, but it also reveals the latter tends to underestimate traffic.
Audience and Demographics Analysis
SEMrush provides a way to view how your audience overlaps with your competitor’s. You can also analyze audience overlap up to five sites at a go using SEMrush’s Traffic analytics tool. Besides, you also get access to audience demographic analysis, including gender and age, and their respective interests and preferred brands. On the other hand, Similarweb also analyzes demographics, but you won’t check the audience overlap.
Similarweb has a free version that is very limited in functionality. Using the free version on Similarweb, you get access to 5 Results Per Metric, 1 Month of Mobile App Data, and 3 Months of Web Traffic Data. For any serious marketer, that is not enough. But the availability of a free tier is a good move. However, Similarweb offers complicated pricing details with each country database priced individually, and you also have to pay for some features separately.
For SEMrush, their pricing is straightforward, but there’s no free tier. The platform only offers a 30-day trial for some of its packages. There are three packages; pro, Guru, and business. Pro goes for $99.95 per month, $199.95 per month for Guru, and $399.95 monthly for the business package best suited for agencies, eCommerce, and extensive business. Subscribing to SEMrush on an annual basis is a smart move because you could save some cash, up to 16% off. On SEMrush, each package includes a host of different marketing tools for PPC, SEO, traffic analysis, and more, in addition to website traffic analysis.
Verdict: Which Tool Should You Choose?
The main point of comparing the two is to give you an insight into the tool that offers better value for money. In general, you won’t go wrong choosing SEMrush over Similarweb.
And here are the reasons why. SEMrush provides more than just website traffic analysis. On top of that, SEMrush’s traffic analysis is more in-depth than what Similarweb offers. For instance, you get audience overlap analysis, traffic journey, access to historical data, and more.
SEMrush also offers a variety of tools for bloggers and marketers. On the other hand, Similarweb is limited in functionality. And the fact that you have to pay to access each country’s database individually and select tools separately, make it less appealing. Similarweb is also secretive on its pricing plans, which could be a turn-off as well to some.
