Keyword research

There seems to be a tie in this Semrush vs Similarweb feature. Both enable keyword search, sorting, comparison, search, lists, and gaps.

While they offer almost the same keyword research options, they vary in terms of insights. The power of keyword research an SEO platform provides is measured by the size and quality of search data it provides.

For instance, Semrush has over 40 trillion inbound links and around 22.3 billion keywords stored in its database. This lets users perform more extensive research.

Semrush vs similarweb

On the other hand, Similarweb may have a diverse database, but it’s unknown.

On-page SEO

On-page SEO is crucial for search engines to identify your website’s content and show it on the search engine result pages (SERPs) on relevant queries. When offering basic to advanced on-site or technical SEO features, Semrush beats Similarweb in most aspects. It’s understandable since Semrush was designed as an SEO tool.

Both platforms offer solid website analytics and audit features, which detect on-page SEO issues and suggest improvements. They also provide competitor benchmarking and exceptional UX ideas.

However, Similarweb lacks many essential on-page SEO features that Semrush offers. These include an on-page SEO checker to scan keywords in landing pages, technical ideas, semantic keyword suggestions, a log file analyzer, a markup report generator, and much more.

Semrush On-Page SEO Checker

So, in this Semrush vs Similarweb metric, Semrush is a clear winner.

Off-page SEO

Off-page SEO primarily includes building a website’s domain authority and recognition through authentic backlinking. It ensures your site ranks higher on the SERPs at the right keywords. Both Semrush and Similarweb provide users with helpful features to level up their off-page SEO game.

You can perform backlink analytics with both platforms, monitor your inbound links, and avail of the right link-building opportunities. They also provide a backlink gap analysis to identify the high-authority links you are not using, but your competitors are. This helps you find efficient and impactful backlinks.

However, Semrush offers some features that Similarweb doesn’t. These include backlink audits, automated link-building outreach, and bulk analytics capabilities. But in Similarweb’s defense, this tool lets users explore opportunities for industry-wise referrals, which can be challenging with Semrush.

Semrush Bulk Backlink Analytics

Overall, Semrush is a winner in this aspect, too.

Position tracking

Position tracking or rank tracking allows users to track a website’s position for a specific keyword. This includes your own website as well as your competitor’s. With this feature, you can easily monitor your efforts and see how they impact your rankings.

Moreover, you can track the pages with the highest and the lowest traffic. Both Semrush and Similarweb offer an efficient position-tracking feature. You can evaluate your website’s SEO performance based on filters like keyword tagging, filtering, and sorting.

With both platforms, you can also extract detailed reports.

Semrush and Similarweb also allow you to set your targeting to location and device type. So, we can call it a tie here.


Local SEO

Local SEO is another metric in this Semrush vs Similarweb in which Semrush seems to have a lead. If your target audience also includes local clients and customers, local SEO is as important for you as on-page or off-page SEO.

Semrush possesses some great local SEO features, including listing management that handles your listing on Google Business Profile (formerly Google My Business) and review management that caters to customer reviews. This tool also has a local ranking feature that gives you suggestions for boosting your site’s local SEO efforts.

Unfortunately, Similarweb lacks all these features.

Content marketing

Your digital marketing campaigns are incomplete without content marketing. Fortunately, both Semrush and Similarweb offer basic to advanced features that help you create, monitor, and optimize the best content.

With both platforms, you can track your competitors’ high-performing content to optimize your website accordingly. You can also get excellent content ideas.

However, Semrush is a step ahead of Similarweb in content marketing. It also helps you research the market, write SEO-based content, and research topics. Moreover, this SEO tool has a content marketplace where you can find, connect, and hire talented content writers.

Semrush Topic Research Page

Since Similarweb lacks these features, we can give Semrush additional points here.



Semrush and Similarweb are great for managing advertising campaigns. You can use any of them to monitor your competitors’ ad strategies and evaluate your campaign’s performance. Both platforms also enable you to identify your ad budget, semantically linked keywords, and keyword gaps.

But unlike Similarweb, Semrush allows you to manage your keywords for PPC campaigns. With its Keyword Manager, you can organize your chosen keywords in suitable baskets and use them when creating campaigns.

However, Similarweb has the upper hand over Semrush in creating and managing display ad campaigns. The platform suggests the most successful ad creatives based on your competitor’s search. It also gives you a list of channels to display the ads and the total campaign cost.

Similarweb Display Ad Manager

So, there is no winner in this factor of the Semrush vs Similarweb one-on-one. Both platforms are excellent on their own.

Social media marketing

Semrush and Similarweb are pretty helpful for SEO and SEM, but do they have any features for SMM (social media marketing)? Yes, they do.

You can manage your ad campaigns on social media sites with both platforms. Moreover, you can also keep an eye on your competitors’ social media accounts to find strategies that are working for them.

Similarweb Social Media Overview

So, which tool ranks better in the SMM aspect of Semrush vs Similarweb comparison? Our vote goes to Semrush.

Semrush also enables users to manage social media pages and groups and create posts. You can also track your posts’ performance and optimize them where necessary. Unfortunately, Similarweb doesn’t offer these social media management features.

To help users analyze websites, Semrush and Similarweb collect data from different sources. Both platforms claim to extract data from credible sources while complying with the ethical guidelines.

Semrush uses anonymous behavioral data from various internet-based third-party sources. It also tracks social media networks’ public APIs and other sources of specific users from relevant marketing channels.

Both tools may sound similar in features, right? They are both also great for startups, small businesses, and large enterprises. So, how can you choose one? Let’s summarize this Semrush vs Similarweb one-on-one.

If you want more data about SEO, PPC, and online visibility, choose Semrush. Similarweb provides powerful insights into audience behavior, site traffic, and competitor websites, but it lacks advanced SEO features.
