SimilarWeb vs SEMrush What You Need to Know

Whether you’re a marketer, blogger or just about anyone who works with the goal of growing an audience online, you must have a profound focus on creating optimised, relevant web content.

However, creating this content without a guide or any direction can be incredibly difficult and without exaggeration, is essentially a stab in the dark.

If you’ve not got a handy SEO tool on your side, you won’t know whether you’re creating content that’s going to garner clicks and be a magnet for audiences, or essentially be an un-visited page on your website.

That in mind, if you have a dependable SEO tool, then you’re on the right track.

Today, two of the most popular SEO tools are SEMrush and SimilarWeb. Both of which have their reach spread across the web, quite literally, to ensure you’re getting all of the essentials and insightful data you need to create content, adjust your domains and link correctly to get as much web exposure from the search engines as possible.

With all that said, let’s take a look at SimilarWeb vs SEMrush and why you might what to consider one over the other.

To ensure we’re getting you everything you need to know, we’ve broken our comparison down into a few essentials.

We’ll be taking a look at both of these platform’s feature sets, the types of data they offer, the location of this data, how accurate it is and more. With all of these points out of the way, you should be able to make a well-educated choice between SimilarWeb and SEMrush for your own use, or for use in your agency.

SimilarWeb vs SEMrush – Detailed Comparison

When you take a look at SEO tools, it’s imperative that you choose something that is as detailed as possible and offers up as much easy-to-understand data as you can get your hands on.

You’ll want to make sure that you’re getting as many useful metrics as you can because these are what will make your content creation activities and marketing processes effective. This data is what is essentially driving your website’s content and campaigns, and if it’s skewed or inaccurate, you’re on track to losing out to all your competitors.

To kick things off, SEMrush is a website or SEO tool in which you’re able to find essentially all the tools needed for PPC advertising, SEO enhancement, social media marketing and content creation.

When we look at SimilarWeb, this platform is designed to give you insight into rival web stats and not too much else.

That in mind — SEMrush offers a little more edge than SimilarWeb when it comes to metrics on the web, though SimilarWeb’s approach to analytical data still offers enough information to compete with SEMrush, at least for marketers.


SimilarWeb vs SEMrush Features

Now that we’ve outlined the main fundamental difference between the two platforms, we’ll take a look at all of the primary features you’ll find on these two services and why one might be better than the other.

We’ll also let you know which service we stand by the most, more than the other as per each feature category.


Regional and Internal Data

To kick things off, SEMrush offers a tonne of both local and internal data points for marketers looking to either focus on a global audience, or to keep things at home for local businesses.

You’ll find datasets on more than 190 countries available here, and the ability to narrow down these all by filters. Whether it’s location, or anything else, you can filter with just one click.

To end, all this data is available under the one subscription you have with SEMrush.

To SimilarWeb, there is a global dataset of metrics here too, based on a range of different locations from countries to local regions, however each of these databases is paywalled.

That in mind, you’ll need to select the data you want, or from the nation you’d like and purchase this dataset separately. It’s also important to note that each dataset is priced differently to one another — which can be a little annoying.



Traffic Analytics


Traffic Source Data

When it comes to website traffic data and analytics, you’ll already know that there are a few different types of traffic and web data. These are organic search, direct, paid search, referral and social. All of these datapoint metrics are covered by both SEMrush and SimilarWeb.

SEMrush offers plenty of traffic source information and an overview of each, depending on the search term you’ve input into the bar at the top of the website.

You’ll be able to see all of these insights and get lots of information on how these websites are performing, but also how they got their hands on this web traffic and from which channel.

On top of this invaluable data, SEMrush also offers up information on website advertising campaigns. That means if you’re interested in a rival website’s current running campaigns or ads, you can simply click through to the advertising section and see all of this data form keyword strategy and content, media and more.

This is essentially one of the most effective ways to gain an edge on the competition.


When we move over to SimilarWeb, you’re able to see a little more detail when it comes to the traffic analysis.

That in mind, SimilarWeb does offer everything SEMrush does, at least with regards to traffic metrics, however, you’re going to get a little more detail here which includes things like emails and some specific advertisements — something SEMrush doesn’t yet offer.


Traffic to and from Popular Pages

When we take a look into metrics from popular pages, it’s odd to find that SimilarWeb has recently retracted their ‘Popular Pages’ metric that previously enabled a look into a tonne of data related to the traffic coming to and from popular pages.

That said, SEMrush is the only option of the two to offer popular page traffic information. You’ll find this data under the ‘Top Pages’ drop down at the top of the page, where you’ll see all of the most popular pages on a specific website. Here you’ll be able to spot whether traffic comes from an internal web page, or an external website.

This data is great to have in that you can easily find where and how rival websites are gaining the most traffic and which types of website traffic are pushing their pages to be the most popular on their sites.

All of this data can also be narrowed on SEMrush to give you a better insight into whether this traffic is from unique visitors, where these visitors came from and if there are different entrance sources for this type of traffic.

Again, great data to have if you’re looking to mimic a rival’s advertising campaigns or one-up them on a specific webpage.


Mobile Data Analytics

When it comes to the mobile-first age, data from smartphones and tablets is also integral in assisting with improving SEO and getting your websites ready for all of the mobile users hitting the market.

As with the international data, SimilarWeb charges a fee for the mobile data, whereas SEMrush offers all of this to their customers under one blanket subscription.

You’ll be able to find the same metrics on mobile data as typical browser data here, which means everything from volume and more.


Detailed Audience Demographics and Analytical Data

Another key metric that comes from website traffic is audience demographic data, which is essential to marketers looking to understand their customer base, or audience and capitalise on these potential consumers.

The SEMrush platform gives a tonne of information on demographics which covers everything from gender and age through to interests and more. You’re able to find this data underneath the Market Explorer tool which means it’s in a simple and easy to find place.

With this data you’re able to quickly build customer profiles for marketing activities, making it an essential metric for store-based blogs and other sales-focused websites.


Over to SimilarWeb now, and you’re able to find a swathe of demographics too, which includes geographic location, interests and more. Again, all of these metrics are invaluable to marketing teams.

It’s also important to keep in mind that SEMrush has an audience overlap feature here, which SimilarWeb lacks, making SEMrush a winner for the analytical data segment.


Website or Domain Category Analysis

For our readers who need an insight into an industry’s top websites, or a category’s leading blogs, websites or stores, both SEO tools have a feature to assist with this.

However, SEMrush’s option is the Market Explorer tool we mentioned above, making it rather lacklustre when compared to SimilarWeb’s.

You’ll be able to type in a specific brand or an industry category into the SimilarWeb tool and see a tonne of different domains showcased which are linked to these markets, based on audience size, ranking or popularity.

SEMrush does this through the Market Explorer that we highlighted earlier in the article, which means you’re able to type in your category or industry and have this data showcased in a relatively simple way, however, the information isn’t overly breathtaking.

On to SimilarWeb’s market analysis and we’re happy to that the information showcased here is incredibly easy to digest and is insight-rich too. You’re able to see everything from market leaders, traffic share as well as data on how your own website matches against these brands.

With this data in tow, you’ll have somewhat of a clear direction on what to focus on as you’re going to be more in tune with who your competitors are, and be able to replicate or directly compete with their online activities.

One feature we do wish either of these tools had was a growth or YoY growth metric for each industry player’s website traffic or market share.

To end, SEMrush does offer this feature in the subscription cost, making it easily accessible.


Historical or Archival Data

For the users who need access to long-term traffic data, the SEMrush tool offers this data all the way back to April of 2016 included in any plan on the service. That in mind, you’ll have access for at least the past four years.

On SimilarWeb, you’re restricted to historical data depending on your subscription — which means on the basic plan you’re going to see data capped at 12 months. To get a further look back in time, it may be worth it to upgrade your plan, though for most users the past year should be sufficient.


Data Accuracy

Without a doubt, one of the more important points when it comes to SEO tools is data accuracy.

You’re going to be relying on this data for a tonne of sensitive processes that could lead to the success or failure of your website, and it’s imperative that the data you’re using is accurate and trustworthy.

Both of these platforms make use of code which uses a clickstream algorithm for the collection of data as well as projections and estimation which means you’re going to see a little difference between what is truly accurate and what isn’t — though this should be incredibly minor.

To add, when comparing both SimilarWeb and SEMrush information and Google Analytics metrics, you will notice a difference in the data points. However, these differences aren’t too worrisome.

To keep things brief, SimilarWeb and SEMrush did match their data quite closely when datasets became quite large with both platforms hitting almost identical accuracy levels when the popularity of websites was between 50 thousand and over 500 thousand visits.

However, for the smaller website with 0 through 49 thousand visits, SEMrush was far more accurate than SimilarWeb. In fact, for the smaller-end of the scale, SimilarWeb did become near-purposeless for data accuracy.

In all, SEMrush does an excellent job at data analysis and accuracy when compared to SimilarWeb on the smaller end of the spectrum, though once things did become a little more popular, both platforms were virtually identical.

It’s also good to see that on the SEMrush platform there are small banners stated that ‘Estimated Accuracy’ is used here, keeping this as transparent as possible.

To end, both of these platforms will be fine for all users on larger websites beyond 50 thousand visits, though getting accurate data from websites that tend to be a little smaller than this can be challenging.


SimilarWeb vs SEMrush Cost

With all of the major features and tools out of the way, it isn’t too hard to see that both of these services do come with a tonne of essentials you’ll need to improve your website’s SEO.

Either of these options are fantastic, though, without pricing involved it’s hard to determine whether one is better value for money than the other — which is particularly important for those cost-conscious marketers.

That said, let’s take a look.


On SEMrush you’ll be paying $200 per month for all of the tools we mentioned above, including access to all of those global and historical databases. You’re essentially having everything bundled into the one service.

To add to this, there’s the famous SEMrush database of keywords too which is also included in this price — and we’re going to say this is a steal.


On the other end, SimilarWeb has a rather complex pricing structure. All of the country metrics in the service’s database are priced at a different cost and you’re going to need to invest in each of these separately.

With that in mind, you also won’t have access to as much data as you do on SEMrush. This is down to the fact you’ll need to buy information on mobile data, top pages and location data separately too.

That in mind, SimilarWeb can become quite expensive depending on how much data you need to invest in separately.

One last thing to keep in mind is that SimilarWeb doesn’t even have a fixed price and is quite expensive, though this will change depending on which market you’re in.


These two pricing structures in mind, we’re painting a resounding ‘pick this one’ banner above SEMrush above SimilarWeb.






Which is Better? SimilarWeb vs SEMrush

With our entire review and comparison out of the way, we’re going to say that both of these platforms are incredibly useful and offer some essential metrics that can lead you and your website to success.

Both have datasets that are far-reaching and contain enough insight and metrics to understand what the competitors are doing and what you need to do to stay one step ahead of their marketing and content creation.

That said though, SEMrush offers so much value for money that it’s quite difficult for us to suggest SimilarWeb over SEMrush.

For our readers who only need access to traffic analytics and not too much else, it would be worth your while and money to subscribe only to the Traffic Analytics tier from SEMrush above the entire service.


All of that noted, we stand by SEMrush as being the winner between the two. However, you may find an interesting feature or tidbit on offer from SimilarWeb that makes it a little more enticing than SEMrush.
