I’m currently managing an eCommerce site and looking for recommendations on free SEO tools that can help with traffic analysis. I need insights into visitor behavior, keyword performance, and overall site health to improve our search engine ranking and drive more organic traffic. While I know there are several premium tools out there, my budget is tight at the moment, so I'm particularly interested in any effective free tools you’ve had success with.

Specific features I’m looking for include:

• Detailed traffic analytics
• Keyword tracking and research
• Competitor analysis
• On-page SEO audits

Additionally, if anyone has experience with eCommerce SEO agencies that offer free tools or resources, I’d love to hear your thoughts. Any suggestions or experiences you can share would be greatly appreciated! Thanks in advance for your help!
