How to Get the Most From These Tools
These tools are most effective when used as part of your regular content and campaign workflows — not as one-time checks. Here's the recommended approach:
- Before publishing any page, run your title and description through the Meta Preview tool. Fix anything that's truncated or too vague.
- Check social sharing with the SERP & OG Preview. Make sure your Open Graph tags produce a clear, clickable card on Facebook and Twitter.
- Add structured data to key pages using the Schema Generator. FAQ and Article schemas are the fastest path to rich results.
- Tag every external campaign link with the UTM Builder so your analytics correctly attributes traffic sources.
- Review your robots.txt with the Robots.txt Generator whenever you launch a new section of your site or change your URL structure.
- Check SMS costs before sending with the SMS Segment Calculator — a single emoji can double your per-message cost.
Frequently Asked Questions
Are these tools really free?
Yes. All 13 tools are completely free with no sign-up, no usage limits, and no feature gating. Most run entirely in your browser. The SEO Page Analyzer uses a lightweight server fetch to avoid CORS, but no data is stored.
Which tool should I start with?
Start with the Meta Title & Description Preview. Optimizing your title tags and meta descriptions is the highest-impact, lowest-effort SEO improvement most sites can make. A well-written title can meaningfully improve click-through rates from search results.
Is my data safe?
Yes. Every tool runs 100% client-side in your browser. Nothing you type — URLs, titles, descriptions, robots.txt rules, campaign parameters — is transmitted to a server, stored in a database, or shared with anyone. You can verify this in your browser's network tab.
Do I need to know code to use the Schema Markup Generator?
No. The generator uses a form-based interface. You fill in fields, and it outputs valid JSON-LD code that you can copy and paste into your page's HTML. The tool includes implementation instructions for various platforms.
Can I use these tools for client work?
Absolutely. These tools are designed for anyone managing websites — whether it's your own site, a client project, or an employer's domain. There are no restrictions on commercial use.
