The decision to use a SEMrush or Similarweb can be difficult. I have used both and found them to be a little different in their search results. When it comes to deciding which is better, there are a few factors that you need to consider before making your final decision.
This blog post will compare these two tools based on their pricing plans, features offered, customer reviews and testimonials, as well as pros and cons for both products.
Short Summary: SEMrush vs Similarweb
In short, Semrush and Similarweb are great at what they do, but more specifically SEMrush would be a better choice because it has a lot going for it.

Also, it’s a whole lot cheaper than the competition while still delivering accurate insights which give businesses more control over their situations.

Semrush Data Collection Tool Review
SEMrush is well known for its keyword database and clickstream data. The company’s ability to use these two resources, in tandem with each other as tools of analysis rather than relying on just one or the other alone, has made SEMrush one of the best SEO tools in the market.
The Semrush data collection tool collects data from the internet and stores it in your Semrush database, which can be used to build backlinks and find keywords for SEO purposes.
SEMrush’s basic search features allow you to find and analyze information on any website, blog, or domain name in about 2 minutes. The data captured by the basic keywords search includes:

Summary: Similarweb and Semrush Data Collection
Similarweb is a fantastic tool for overall rankings and social performance data, while Semrush gives you valuable insights into organic search results and paid listings.
Semrush is my personal preference when tackling SEO-related projects. Because it provides the meat-and-potatoes of what clients are paying for – insight into search engine optimization practices that affect ranking positions.
Semrush pays attention to the top five keywords driving traffic and how obscure keywords contribute positively or negatively towards your site’s success.
Competitive Analysis Tool
Semrush Competitive Analysis Tool Review
A Competitive Analysis Tool is a tool used by SEMrush to view the keywords, domains, AdSense earnings, backlinks of competitors.
The Competitive Analysis Tool was designed to determine the competitiveness of websites for SEO purposes. It provides an overview of how competition on search engine result pages will affect your site’s rankings, given all other factors being equal.
This knowledge can help you adjust your strategy accordingly, resulting in success despite this factor being present on SERPs. The more competitive a keyword or domain is on SEMrush’s Database, the more difficult it will be for your site to rank higher than these results in search engines – even if everything else about your site were equal.


This powerful tool allows companies and agencies alike to gain critical insights into their competitors’ search strategies. Also allow them to view their organic visibility across both desktops, mobile, app, video, news, image search sources in addition to identifying new keywords by utilizing Keyword Expansion Mode.

What makes SimilarWeb different is that it extends this assessment not only towards competitors but also other similar sites, which enables the user to benchmark their performance and learn about proven techniques to find new growth potentials.
Summary: Similarweb and Semrush Competitive Analysis Tool
Semrush Competitive Analysis Tool is better because you get all the features for less.
Similarweb does not offer many additional features beyond what you get with Semrush. As a result, the only elements unique to Similarweb are its backlink audit tool and its rank tracking solution capabilities.
Both Tools need to be used in addition to access to competitive analysis data. That is only exclusively available through Semrush’s service, which becomes extremely expensive; when utilized every month. Considering how much it could cost per month over time if annual subscriptions are cheaper.
Social Media Analysis Tool
Semrush Social Media Tool Review
SEMrush is known for its influential social media analysis. One of the best features it has to offer is Social Media Trackers, you can track your competition and see what they’re doing on their channels. SMA tool gives you a better idea about how often posts should go out to achieve desired results in online marketing.

Similarweb Social Media Tool Review
SimilarWeb is an excellent tool for measuring the amount of social media traffic on a particular site. Through their Website Analysis tab, you can track various aspects of how many people are visiting your website from specific sources, and at what times throughout each year or month during particular days.

One of the best features of this tool is that it understands which platform the result has come from. So, for example, if somebody shares a link on Facebook, there might not be any corresponding Twitter post because no one has tweeted about the article. However, with Similarweb, you can still see what sort of traffic there’s been on Twitter, even if nothing is shown.
It also analyses each platform for what keywords are most frequently shared by users (and which ones aren’t) and then automatically scans new pages to show these exact keywords.
Summary: Semrush vs. Similarweb Social Media Tool
Semrush tends to have an extensive index of social media platforms but is better for looking at areas where a lot of noise has been generated. It shines in helping with understanding brands and how they work – brand mentions, popularity ranking scores from the annual Google sentiment analysis index, best relevancy queries, etc.
On the other hand, Similarweb social media analysis tool also provides us with good information. One thing where the Similarweb tool lacks, it doesn’t offer in-depth data. At the same time, Semrush gives us a complete social media toolkit that provides a comprehensive insight into social media traffic for our website and our competitor site.

The Similarweb pricing plans start at $249 per month, but that does not include unlimited reports or export quotes to Excel. For that, you’ll need to upgrade your account for a piece of extra information based on other needs.

Frequently Asked Questions
Is Similarweb accurate?
SimilarWeb is accurate for getting an approximate value but not fair in terms of comparing different sites.
There are some cases where a similar web tool will not produce reliable data for a specific site. For example, if a company only uses customized software to track specific site metrics, the info may not be available in this search engine tool.
However, that does not mean that the data is inaccurate; it simply means that this standard web analytics tool’s specialized software wasn’t captured.
How does Similarweb get its data?
Similarweb gets its data from various sources. Google AdSense, Google Analytics, Alexa web traffic ratings, Compete.com and Quantcast, are all used to provide estimates of site visits for SimilarWeb.
The primary source is the widespread use of digital installs with which you have interacted at some point on your desktop or mobile device. For example, if you have downloaded a browser extension or app that offers the usage of their service to people who visit sites within their installation audience reach. So, an analogy would be how many clicks were made by visitors to your site after they installed an adware product onto their machines.
How accurate is Semrush?
Semrush is one of the best and most accurate SEO analysis tools available. It’s also very affordable, with the primary license running about $99USD per month.
Above all else, it has to be precise in what it does and highly effective when analyzing everything from keywords in search results to several backlinks on specific websites. Semrush checks in at 88% accuracy when finding old versions of websites like eBay and Amazon.
How to use Similarweb chrome extension?
SimilarWeb has many features you can adjust for different functions. To use it on Chrome, install the extension by following these steps:
- First of all, go to the Chrome Web Store and search for Similarweb-Chrome extension
- In case that there is a direct link available, click on the install button right away
- If not, look around the page and scroll down until you see “ADD TO CHROME.”
- Once installed, it will show up in your browser with its icon of an orange shield with a black arrow going from left to right. Now, this is what you need to do to use the Similarweb chrome extension.
Conclusion
There’s no reason not to try both and see how they work for you.
It comes down to preference in what metrics you want to be tracked when you would like the information gathered, and what information you need. I prefer Semrush due to its hourly updates on keyword data, while Similarweb only updates every 24 hours.
I also find Semrush easier to navigate than Similarweb. My favorite feature of it is the fact that it answers all your questions so quickly.
Moreover, SEMrush has features that I don’t see in Similarweb, such as keyword or domain-related alerts, backlink research, and mobile app marketing tools. The only services similar to what isn’t offered by SEMrush are web stats and competitor monitoring services.
