Similar Websites by Traffic: How to Identify Them for Free

Finding websites similar to yours in terms of traffic volume is one of the most useful tasks in SEO, content marketing, and competitor analysis. In 2026, you no longer need to pay hundreds of euros a month to access this information. Tools exist that allow you to discover similar sites, compare their traffic, and extract actionable insights easily, with a free option available.

If you have a blog, an online store, a SaaS platform, or any type of website, knowing who your real competitors are for traffic helps you discover content opportunities, acquisition channels you're not taking advantage of, link building strategies, and growing niches you can target before others.

In this comprehensive guide you will learn what traffic lookalike websites are, how to identify them for free step by step, and what tools to use, with a special focus on Lookkle's capabilities in 2026.

What are similar websites by traffic?

When we talk about websites with similar traffic, we're referring to websites that compete in the same digital space: same theme, same potential audience, similar traffic sources, and ranking in the same search results. They aren't always direct product competitors, but they do compete for the same user's attention on search engines, social media, or referral sources.

Identifying them correctly is useful for:

• Discover which keywords are working for sites in your same industry.

• Analyze where your traffic comes from and replicate your best channels.

• Detect content patterns that generate recurring visits.

• Find backlink opportunities that others already have.

• Validate niches before investing time and money in creating them.

Why is it important to do it in 2026?

The web traffic landscape in 2026 has changed. Now, traffic doesn't just come from Google: ChatGPT, Perplexity, DeepSeek, and other AI engines are increasingly sending visits to pages. Lookkle, for example, already includes the detection of traffic from artificial intelligence platforms among its metrics, providing a more complete view of the real-world ecosystem of visits to any website.

Furthermore, well-known traditional tools like SimilarWeb or SEMrush have very expensive paid plans for access to comprehensive data. By 2026, alternatives like Lookkle offer comparable features for a fraction of the price, with a limited free option to get started without investment.

How to identify similar websites by traffic

Lookkle offers several specific tools to discover similar websites and analyze their traffic in detail. Here's the step-by-step process.

Step 1: Access the competitor analysis tool

Go to Lookkle Competitor Analysis Tool. It's the leading tool for automatically finding similar websites.

Simply enter the URL of your website or any domain you want to analyze. Lookkle automatically generates a list of up to 20 similar sites within the same industry, with key metrics for each.

Step 2: Review the similar websites identified

After entering the domain, Lookkle displays the following for each similar website found:

• Visual preview of the site (screenshot).

• Total estimated web traffic.

• Country with the highest volume of visits.

• Site creation date.

• Traffic sources: organic, direct, social, referral, email, and AI traffic.

• Percentage of new vs. returning users.

• Bounce rate and average time on site.

• Pages viewed per session.

This allows you to understand at a glance which websites in your sector are performing best, how their visitors behave, and where their actual traffic comes from.

Step 3: Use the Web Traffic Checker for individual analysis

Once you have the list of similar websites, you can delve deeper into each one using Lookkle's Web Traffic Tool. This tool allows you to analyze any domain and obtain:

• Traffic history of 3 to 36 months.

• Traffic broken down by country, device and source.

• Organic, social, direct, paid, referral and AI traffic (ChatGPT, Perplexity, DeepSeek).

• Global ranking, by country and by category.

• Audience demographics: age, gender, education level, income.

• Engagement metrics: bounce rate, pages per session, time on site.

With this data you can build a real map of where sites in your sector are gaining traffic and what opportunities you have to grow.

Step 4: Analyze keywords to find more opportunities

Another layer of analysis that Lookkle offers within the same workflow is keyword research. You can see which keywords are bringing organic traffic to the identified similar websites, their search volume, difficulty, CPC, and intent.

This makes searching for similar websites much more actionable: you not only know who your competitors are in terms of traffic, but also what content and keywords are working for them. Use the Organic Keywords tool to research successful keywords among your competitors.

What data can you get for free with Lookkle?

Lookkle offers a free plan with daily reports. While the free reports are limited, they allow you to explore similar websites without registering or paying. For access to full reports and a higher number of daily queries, the Starter plan starts at €19.95 per month, with access to 25 daily reports per tool.

Compared to more well-known tools on the market, SimilarWeb and SEMrush offer paid plans that cost over $100-$200 per month for access to detailed traffic data. Lookkle provides a very comprehensive level of competitive analysis for a fraction of that cost.

Other complementary free tools

Although Lookkle is the most comprehensive option for this task, there are other free options that can complement your analysis:

• Ahrefs Traffic Checker (free): estimates organic traffic from any domain, but only covers traffic from Google, not the total.

• SimilarWeb (free tier): offers limited estimated traffic data, with restrictions in the free plan.

• SEMrush (free tier): allows limited queries of estimated traffic and keywords.

• Sitechecker: includes a search engine for similar sites, although with less depth in the data.

Lookkle's advantage over these free and basic paid alternatives is that it combines in a single workflow the search for similar websites, traffic analysis, breakdown by source, history and keyword analysis, without the need to combine several tools.

How to leverage data from similar websites to grow

Once you've identified websites similar to yours based on traffic, the analysis doesn't end there. The most valuable part is turning that data into concrete actions:

• Improve your SEO: Review the titles and meta descriptions of similar websites with lower bounce rates. If they're better optimized, it's a direct sign of improvement.

• Replicate channels you're not using: If a similar website gets a lot of traffic from social media or AI platforms and you don't, it's an acquisition opportunity you're ignoring.

• Discover untapped keywords: With Lookkle's keyword analysis, you can see which organic terms bring traffic to your competitors and identify which ones you haven't yet targeted in your content.

• Build a backlink strategy: If a similar website has a lot of referral traffic, use Lookkle to identify its linking domains and contact those same sources.

• Detect niche trends: Lookkle's 3-36 month traffic history lets you see which websites are growing and when, making it easier to anticipate demand spikes or industry changes.

Practical example: how the complete flow works

Imagine you have a tech blog and you want to know who your real competitors are in terms of traffic. The complete process with Lookkle would be:

1. You go to Lookkle Competitor Analysis and enter your domain.

2. You get a list of up to 20 similar websites in your same niche with basic traffic metrics, source, and user behavior.

3. You select the 3 or 4 websites that receive the most traffic and analyze them with the Web Traffic Tool.

4. You notice that one of them receives a lot of organic traffic from searches related to mini PCs and has a low bounce rate. You review its content and identify keywords that you aren't covering.

5. You notice that another similar website is gaining increasing traffic from AI platforms like ChatGPT. You decide to optimize your content to appear on those types of sources as well.

6. With Lookkle's backlink analysis, you can identify which technology blogs link to your similar competitors and contact them to obtain the same links.

In less than an hour you have a clear map of who is gaining traffic in your niche and what you need to do to compete better.
