Frequently Asked Questions
Can I really do SEO with only free tools?
Yes. Free tools cover 80% of SEO needs. The remaining 20% (advanced competitor analysis, large-scale tracking) requires paid tools, but you don't need that at startup stage.
What's the most important free SEO tool?
Google Search Console. It's the only tool that shows actual Google data about your site. Everything else is secondary.
How do I track keyword rankings for free?
Use Google Search Console's "Performance" report. It shows average position for queries. For more detailed tracking, manually check rankings or use limited free tiers of rank trackers.
Are AI SEO tools worth using?
AI tools (ChatGPT, Claude) are excellent for research, outlines, and optimization suggestions. But don't use them to write final content—Google can detect AI content and may deprioritize it.
How often should I check my SEO performance?
- Search Console: Weekly
- PageSpeed Insights: Monthly
- Technical audit: Quarterly
- Competitor analysis: Monthly
What about Core Web Vitals?
Core Web Vitals are confirmed ranking factors. Use PageSpeed Insights to check them. Aim for:
- LCP (Largest Contentful Paint): less than 2.5s
- FID (First Input Delay): less than 100ms
- CLS (Cumulative Layout Shift): less than 0.1
Should I use paid tools when I scale?
Yes, when you have:
- 10K+ monthly visitors

Until then, free tools are sufficient.

Combine:
- Google Suggest (autocomplete)
- AnswerThePublic (questions)

How do I build links without paid tools?
- Create quality content worth linking to
- Guest post on industry blogs
- Get listed in relevant directories
