Frequently asked questions
Will these SEO tools actually improve my rankings?
These tools help with the technical and content basics, such as descriptive titles, meta tags, useful slugs, sensible keyword density, and structured metadata. They're not a ranking shortcut, but they cover the on-page work search engines reward.
Do you scrape Google or send queries on my behalf?
BlinkCalc does not submit searches to Google on your behalf. Most SEO tools work on text you paste, while a URL-analysis mode may request the public URL you provide; check the relevant tool disclosure before submitting private links.
Is keyword density still relevant?
Modern search engines use much more than density, but checking density still helps you avoid both keyword stuffing and accidentally omitting your main topic.
How to choose the right tool
SEO tools help shape page metadata, titles, slugs, keyword checks, and structured content before publishing.
Most SEO tools work with pasted text, page titles, keywords, or HTML meta snippets.
