Drawbacks of Similarweb

Similarweb excels at providing a broad view of industry rivals and approximating traffic metrics — but there are significant limitations that may hinder more detailed marketing analysis

Limited SEO Abilities

Similarweb does not provide complete on-page and off-page SEO tools. It is missing essential features such as

• SERP tracking across search engines
• Backlink profile reviews
• Past keyword rankings
• Content performance information by page

For SEO-focused activities like improving domain authority, producing content targeting keywords, and surpassing competitors in rankings, you will need more detailed SEO intelligence software.

Smaller Keyword and Backlink Collections

When compared to leaders such as Ahrefs and Semrush, Similarweb’s crawl size is more limited

• 5 billion keywords compared to 28.7B in Ahrefs or 26B in Semrush
• 3.6 trillion backlinks compared to 43T in Semrush or 35T in Ahrefs

This restricts your capacity to find backlink gaps or long-tail keyword chances extensively.

Limited Traffic Detail

Although Similarweb offers general traffic metrics, it has limited segmentation by

• Channel (for example, organic versus paid versus referral)
• Landing page information
• Detailed bounce rates or time-on-site for each page

Without this degree of detail, it is challenging to improve site structure or refine pages at the start versus the end of the purchase process.

No Deep Demographics or Psychographics

Marketing now is heavily focused on hyper-personalization. However, Similarweb does not report on

• Age, location, interest breakdowns
• Behavioral groups or purchase intention
• Audience overlaps with competitors

Marketers require demographic data to develop sharper content, better advertisements, and prioritize customer groups.

If your team’s work focuses on SEO research, strategic content planning, or predicting upcoming trends, it is time to consider options beyond Similarweb.

Similarweb Alternatives at a Glance

Here is a quick summary of the best Similarweb alternatives, based on their notable abilities and ideal fits for different marketing teams
