Frequently Asked Questions
Can I do SEO for free without paid tools?
Absolutely — Google Search Console, Google Analytics, and Ahrefs free tools give you most of what you need. Paid tools save time but aren't required, especially starting out.
Is Semrush worth paying for?
For serious SEO work at scale, yes. For a new or small site, start with free tools and upgrade when you're earning enough to justify the cost.
Does Google penalise AI-written SEO content?
Google's guidance is that helpful, accurate, people-first content is what gets rewarded — regardless of how it was created. AI content that's thin, inaccurate, or spammy gets penalised. Quality, edited AI content performs well.
