Frequently Asked Questions
Do these SEO tools require an API key? expand_more
No. All tools run entirely in your browser without connecting to any external SEO API. Keyword suggestions are generated algorithmically from your seed keyword using common search patterns, not live search volume data.
How accurate is the SERP Preview? expand_more
The SERP Preview measures pixel widths using the same font rendering logic Google uses, making it a reliable indicator of whether your title or description will be truncated. Actual results may vary slightly by device and query context.
What does keyword density mean? expand_more
Keyword density is the percentage of times a keyword appears in a text relative to the total word count. A density above 3–4% for a single keyword is generally considered over-optimized and may trigger spam filters.
Can I analyze meta tags from a live URL? expand_more
The Meta Tags Analyzer works by parsing HTML you paste into the tool. To analyze a live URL, view the page source (Ctrl+U or Cmd+U) and paste the HTML head section into the tool.
