Keyword Overview Page of Semrush

While both SimilarWeb and Semrush are pretty much identical in terms of keyword research with similar features, there are crucial differences between both that can lead to very different results. 

SimilarWeb vs Semrush - Keyword Overview

The accuracy of keyword research depends on the quality and scale of search data that’s used in the research, and that’s where Semrush seems to have some edge on SimilarWeb. There are more than 40 trillion inbound links in its database to help you conduct your keyword research, while the size of SimilarWeb’s keyword database is unknown. 

Keyword Overview Page of SimilarWeb

However, at the same time it’s also worth noting that while SimilarWeb doesn’t disclose the size of its database, it has been in business for much longer. It was founded in 2007, while Semrush was founded in 2012. Therefore, it’s quite possible that the database of SimilarWeb may be larger than that of Semrush. 

Keyword Overview Page of SimilarWeb

Plus, SimilarWeb claims to rely on fresh weekly data and real-time trends for providing you insights about your keywords, so it can’t be put behind Semrush in terms of quality so easily. 

Other than that, both platforms offer almost similar keyword research capabilities. There’s no clear winner in this first criterion of our comparison. 

Winner: None

#2. Off-Page SEO (Link Building) Features

FeaturesSimilarWebSemrush
Rank monitoringNoYes
Backlink analyticsYesYes
Backlink profile auditingNoYes
Bulk analysisNoYes
Backlink Gap Tracking YesYes
Automated link buildingNoYes

Off-page SEO mainly refers to link building, and both SimilarWeb, as well as Semrush, provide you a number of useful features to build your backlinks in a smarter way. 

Link-Building Features of Semrush

Both of them provide backlink analytics so you can keep track of your inbound links and discover new link-building opportunities at the same time. Semrush’s link building is more like a DIY tool where it gives you insights, and you take actions based on it.

Both platforms also allow you to analyze your competitors’ backlinks and their top referral sources to identify the best possible link-building opportunities. SimilarWeb also allows you to discover industry-wise referral opportunities that you may not necessarily discover sometimes from Semrush.

Finally, the backlink gap analysis feature included in both platforms allows you to discover more link-building prospects by identifying high-authority websites linking to your competitors but not linking back to you. That way you can reach out to them for building backlinks that drive the most impact for your SEO.

However, there are some unique features too that give Semrush a clear edge over SimilarWeb in this department. It allows you to automate your link-building outreach, thus eliminating the need of doing this process manually. It also allows you to track your rankings and also the rankings of your competitors for any of your desired keywords. Finally, it also provides a detailed audit of your backlink profile and bulk analysis of the link profile of your competitors to help you gain the best possible understanding of your link-building requirements.  None of this can be done with SimilarWeb.

Winner: Semrush

#3. On-Page/Technical SEO features

FeaturesSimilarWebSemrush
Site auditYesYes
On-page SEO checker NoYes
Log File AnalyzerNoYes
Markup ReportNoYes
SEO Content TemplateNoYes
User experience ideasYesYes
Semantic ideasNoYes
UX ideasNoYes

On-page SEO, also known as on-site SEO or technical SEO, is an area where Semrush has a clear edge over SimilarWeb, mainly because it’s a tool designed primarily for the needs of SEO. Its robust site audit functionality scans your website for all the on-page SEO issues it may have and then suggests you the changes that you can make to fix them. And while SimilarWeb too does the same, it lacks other on-site SEO features that make Semrush a better option. 

Semrush - Listing Management

For instance, Semrush comes with an on-page SEO checker that can be used to scan any of your landing pages for the presence of keywords in critical areas (i.e. meta tags, title tags, etc). Based on the findings of a scan, the tool can generate numerous ideas for improving the on-page SEO of the page that was scanned. These ideas may range from hardcore technical SEO suggestions to user experience-related suggestions or semantic keyword ideas. SimilarWeb doesn’t offer this functionality. 

Semrush also includes a number of other advanced on-page SEO features, like Log File analyzer, Markup report generator, etc. that are not included in SimilarWeb.  

Winner: Semrush

#4. Local SEO Features

FeaturesSimilarWebSemrush
Listing managementNoYes
Local rankingsNoYes
Review managementNoYes

Listing Management Feature of Semrush

Again, this is an area in which Semrush has a clear advantage over SImilarWeb. If your website thrives on local customers, local SEO is what you need to be done. Fortunately, Semrush provides you with robust tools for this purpose too. Its Listing Management feature can be used to manage the Google My Business listing of your business, while the Local Rankings feature provides you with ideas and suggestions specifically curated for boosting the local SEO of your website and specific web pages.  

Winner: Semrush

#5. Social Media Marketing Features

FeaturesSimilarWebSemrush

Social media managementNoYes
Competitor social trackingYesYes

Semrush is not for SEO or SEM only – it includes terrific social media marketing features too. Not only it allows you to manage your social media handles but also you can use it for creating posts or managing your ad campaigns. You can also analyze the performance of your posts as well as your competitors on social media to learn what’s working and what’s not. 

Semrush Social Media Tracker

SimilarWeb, on the other hand, offers limited functionality in this regard. It can be used for analyzing the social media accounts of your competitors or their ad campaigns, but not for social media management or posting. Performance analysis of your own social media posts can also not be done with it.

Semrush Advertising Research Page

Both Semrush and SimilarWeb provide you with a detailed analysis of your competitor’s advertising campaigns so you can get an idea of how much ad budget you need for a campaign. Both of them also allow you to discover keyword gaps and semantically-linked keywords. However, there are some areas where both of them have a unique advantage over the other. 

Semrush Advertising Research

Semrush is way better than SimilarWeb when it comes to managing your PPC keywords. Its Keyword Manager allows you to add the desired keywords to various keyword baskets for easier sorting and campaign creation. This functionality is not available in SimilarWeb.

SimilarWeb ad Manager

SimilarWeb, on the other hand, also helps you in creating your display ad campaigns by suggesting ad creatives that are working for your competitors, the channels that they are using to display them, and the estimated costs of running such campaigns. This makes SimilarWeb an all-rounder when it comes to online advertising campaign management and monitoring.

Content marketing is also a crucial part of the digital marketing landscape, and both these platforms offer some features to help you with this thing too.  You can identify the top converting marketing channels (i.e. direct, email, social media, etc.) of your competitors using both SimilarWeb and Semrush. You can also get content ideas based on what works and doesn’t work for your industry in both these tools, and you are also allowed to track how your posts and content are performing.

However, Semrush offers much more than that.  It helps you with topic research and market research, provides SEO-based writing suggestions for your content, and also has a content marketplace from where you can hire writers or copywriters to help you with your content requirements. SimilarWeb doesn’t get you any of that.

#8. Payment Plans

Finally, let’s talk about the pricing of both these platforms. Looking at the table given above it’s easy to see that SimilarWeb is a costlier choice in comparison to Semrush. However, that’s not the ideal way to look at it. For a full picture, you must look at what’s offered in both these plans. So let’s take a look at Semrush plans and their offerings first:

And here’s what you get with SimilarWeb in its plans:

SimilarWeb Plans

As you can see, both these platforms have structured their offering in a very different manners. While Semrush has made its suite available in a manner that’s more suitable to digital marketing agencies that cater to multiple clients, SimilarWeb has structured its offering in a way that is more suitable for individual business owners and agencies both. 

SimilarWeb - Plans

In addition to that, unlike Semrush which is more focused on search engine and social media marketing the SimilarWeb suite is also a 360° digital marketing solution so it also includes many things that are not included in Semrush (i.e. media buying research tools, ad creative research tools, etc). Therefore, the higher price is rightly justified and there’s no clear winner.
