Is Krawly a good alternative to SEMrush, Ahrefs, or BuiltWith?

Krawly provides many of the same on-page SEO analysis features as SEMrush and Ahrefs for free, including meta tag validation, heading analysis, keyword density checking, and structured data auditing. For technology detection, it serves as a free alternative to BuiltWith and Wappalyzer. However, Krawly focuses on individual page analysis rather than domain-wide crawling or backlink databases.

Can I use Krawly for lead generation?

Yes. Krawly's Lead Generation tool automatically crawls a website's homepage, about, contact, and team pages to extract email addresses, phone numbers, LinkedIn profiles, Twitter handles, Facebook pages, Instagram accounts, and GitHub links. Results can be exported as JSON, CSV, or Excel.

What data does it show?

Ad creatives (images and text), advertiser name, ad format, and date ranges when ads were active.

Can I see ads from specific countries?

Yes, filter by region/country to see ads shown in specific markets.

How far back does the data go?

The Google Ads Transparency Center typically shows ads from the past year.
