Yo fellow SEO enthusiasts, just found this awesome resource that blew my mind - a DIY SEO audit tool set that won't break the bank (less than $50). I'm talkin' about tools like Ahrefs Site Audit, SEMrush Audit, and Moz Pro's Crawl Test, which offer detailed site audits, crawl errors, and optimization suggestions. Anyone got experience with these tools or know some free alternatives?
