Frequently Asked Questions

Common Questions About Subayoga SEO Tools

Everything you need to know about our browser-based utilities, data privacy, and Google search optimization.

Are the SEO tools on Subayoga.com completely free? +
Yes. Every tool on Subayoga.com is 100% free with unlimited usage. There are no paid tiers, trials, subscriptions, or account registrations required.
How does the Google SERP Simulator calculate title pixel truncation? +
Our simulator uses an HTML5 Canvas rendering engine with Google's exact proportional typography (Arial 20px regular). Rather than counting characters, it calculates the physical pixel width against Google's 600px desktop and 580px mobile truncation boundaries.
Does Subayoga store my website URLs or text content? +
No. Subayoga tools operate 100% client-side inside your browser. No copy, URLs, keywords, or meta tags are ever transmitted to or stored on external database servers.
How do I submit an XML sitemap to Google Search Console? +
Generate your sitemap using our XML Sitemap Maker, click Download sitemap.xml, upload it to your website's root hosting directory, and then enter the URL (e.g., https://yourdomain.com/sitemap.xml) in Google Search Console under the Sitemaps tab.
Why is keyword density important for Google's Helpful Content System? +
Google's modern neural language models detect multi-word n-gram frequency. Over-repeating exact 2-word and 3-word phrases above 2.0% density triggers algorithmic over-optimization penalties. Our Keyword Density Analyzer highlights these risks so you can maintain natural, helpful copy.
