What Exactly is Semrush Competitor Research?

Semrush competitor research is the process of using the Semrush software suite to systematically gather and analyse data about your business rivals. This isn't just about finding out who your competitors are; it's about deeply understanding their digital marketing strategies. The goal is to identify their strengths, weaknesses, opportunities, and threats—a classic SWOT analysis, but tailored for the digital world.

At its core, this research answers critical questions. Which keywords are driving the most traffic to their websites. Where are they acquiring valuable backlinks that you're missing. How much are they spending on paid search, and what do their most effective ads look like.

What kind of content resonates most with their audience on social media.

By answering these questions, you move from guesswork to strategy. For example, a semrush competitor analysis might reveal that a rival ranks highly for a set of valuable keywords you haven't even targeted. This insight immediately gives you a new set of content ideas and SEO priorities. Similarly, seeing their most successful ad copy can inspire your own PPC campaigns, helping you write more effective ads from day one.

It’s about leveraging their efforts and budget to inform your own, saving you time and money.

How to Conduct Semrush Competitors Research: A 7-Step Guide

Getting started with competitor research in Semrush can feel overwhelming due to the sheer volume of data available. Following a structured process ensures you gather the most impactful insights efficiently. Here is a step-by-step workflow to guide your analysis.

Step 1: Identify Your True Online Competitors

Your perceived business competitors might not be your main online rivals. A local shop's biggest search competitor could be a national blog that dominates informational keywords in your niche. Semrush helps you find who you're actually competing against in the search engine results pages (SERPs).

Start by entering your domain into the Organic Research tool. Navigate to the 'Competitors' tab. Semrush will generate a list of domains that rank for a similar set of keywords as you. The 'Competition Level' metric is particularly useful here, as it considers both the number of shared keywords and the total number of keywords the competitor ranks for.

This gives you a data-backed list of your true digital adversaries.

Step 2: Analyse Competitor Traffic and Audience

Once you know who your competitors are, the next step is to understand their audience and traffic sources. The Traffic Analytics tool in Semrush provides a high-level overview similar to what you might find in a tool like SimilarWeb.

Enter a competitor's domain to see estimated monthly visits, unique visitors, and engagement metrics like average visit duration and bounce rate. More importantly, you can see their traffic sources—direct, referral, search, social, and paid. This reveals how dependent they are on SEO versus other channels. If a competitor gets 70% of their traffic from search, you know their SEO strategy is a critical area to analyse.

Step 3: Uncover Profitable Keyword Gaps

This is where the most actionable SEO insights are found. A 'keyword gap' refers to the search terms your competitors rank for, but you don't. The Keyword Gap tool makes this analysis straightforward.

You can enter your domain and up to four competitor domains. The tool will generate several reports, but the most valuable one is often 'Missing'. This shows you all the keywords your competitors rank for (typically in the top 100) that your site doesn't. You can filter this list by keyword difficulty, search volume, and position to prioritise the most valuable, attainable keywords to target next in your content strategy.

Step 4: Find High-Authority Backlink Opportunities

Backlinks remain a crucial ranking factor. The Backlink Gap tool works similarly to the Keyword Gap tool but focuses on referring domains. It helps you find websites that link to your competitors but not to you.

Enter your domain and your competitors' domains. The tool will generate a list of websites that are giving your rivals a vote of confidence through backlinks. These are prime targets for your own link-building outreach. Since these sites are already linking to similar content in your industry, there's a higher probability they will be interested in linking to your high-quality resources as well.

Step 5: Deconstruct Their Paid Advertising Strategy

If you're running or planning to run Google Ads campaigns, understanding your competitors' paid strategy is invaluable. The Advertising Research tool provides a treasure trove of data on their PPC efforts.

You can see the keywords they are bidding on, view their live ad copy, and even see their ad history over the past 12 months. This allows you to identify their most profitable keywords and see how they craft their messaging to attract clicks. Analysing their landing pages can also give you ideas for improving your own conversion rates. This form of semrush rival research saves you from making costly mistakes with your own ad budget.

Step 6: Monitor Their Social Media Presence

While not a direct SEO factor, a strong social media presence can drive traffic and build brand authority. The Social Media Tracker helps you benchmark your performance against competitors across major platforms.

You can track audience growth, posting frequency, and engagement metrics (likes, shares, comments). The tool helps you identify their most successful content, giving you a clear idea of what topics and formats resonate with your shared target audience. This data can inform both your social media strategy and your broader content creation efforts.

Step 7: Assess Visibility in AI-Generated Results

With the rise of AI-powered search like Google's SGE (Search Generative Experience), understanding your visibility in these new formats is becoming crucial. Semrush's AI Competitor Research report is a forward-thinking tool for this.

This report helps you compare your brand's presence in AI-generated results against your competitors. It can identify topics and specific prompts where your rivals are being featured but you are not. This allows you to start optimising your content to appear in these AI-driven answers, preparing your strategy for the future of search.

Key Semrush Features for Competitor Analysis

Semrush is not a single tool but a comprehensive toolkit. For effective competitor research, several key features stand out for their depth and utility. Understanding what each one does helps you extract maximum value from the platform.

• Domain Overview: This is your starting point. It provides a top-level snapshot of any domain's online visibility. You can quickly see a site's authority score, estimated organic and paid traffic, and the number of backlinks. It’s the perfect tool for a quick health check on a competitor before diving deeper.

• Traffic Analytics: This feature offers market intelligence by estimating a website's traffic metrics. It goes beyond just organic search, showing you the full picture of how people find your competitor's site, including direct visits, referrals from other sites, and social media. The audience overlap feature is also powerful, showing you which other websites your competitor's audience frequently visits.

• Organic Research: This is the heart of SEO competitor analysis. It shows you every keyword a competitor ranks for, their position in the SERPs, and the estimated traffic each keyword brings. You can track their ranking changes over time, identify their top-performing pages, and discover new keyword opportunities.

• Keyword Gap: As mentioned in the workflow, this tool is essential for finding strategic content opportunities. By comparing your keyword profile against up to four competitors, you can instantly see where you're falling behind. The 'Weak' and 'Missing' keyword reports are particularly useful for building a content calendar that directly targets your competitors' strengths.

• Backlink Analytics & Gap: A two-part feature set for dissecting link profiles. Backlink Analytics lets you do a deep dive into a single competitor's backlinks, assessing their quality and velocity. The Backlink Gap tool provides the comparative view, showing you exactly which high-authority domains are linking to your rivals but not to you, creating a ready-made list for outreach campaigns.

Pro Tip: When using the Backlink Gap tool, filter the results to show only 'dofollow' links from high-authority domains (Authority Score of 50+). This focuses your efforts on the links that will have the most significant impact on your SEO.

Why Look for a Semrush Alternative?

While Semrush is an exceptional all-in-one platform, it may not be the perfect fit for everyone. There are several valid reasons why a marketer or business might consider an alternative tool for their competitor research needs.

First and foremost is the cost. Semrush is a premium tool, and its pricing can be a significant investment, especially for freelancers, small businesses, or startups on a tight budget. Some alternatives offer a more focused feature set at a lower price point, which can be more practical if you don't need the full breadth of Semrush's capabilities.

Second, different tools have different specialities. While Semrush is a fantastic all-rounder, other platforms are renowned for being best-in-class in specific areas. For example, Ahrefs is widely considered to have the most comprehensive and up-to-date backlink index on the market. If in-depth backlink analysis is your absolute top priority, Ahrefs might be a better choice.

Finally, user experience and interface design play a role. Some users find Semrush's interface, with its vast number of reports and tools, to be complex and overwhelming. A simpler, more intuitive tool like Mangools or SE Ranking might be preferable for those who value ease of use and a cleaner dashboard. The best tool is ultimately the one you'll use consistently, so finding one that matches your workflow and technical comfort level is key.
