SEO Tools FAQs
What is a meta tag generator used for?
A meta tag generator helps you write SEO-optimised title tags (under 60 characters) and meta descriptions (under 160 characters) with a live SERP preview so you can see exactly how your page will appear in Google search results.
Why do I need a robots.txt file?
A robots.txt file tells search engine crawlers which pages and directories to crawl and which to ignore. Misconfigured robots.txt files can accidentally block important pages from being indexed.
What is schema markup and why does it matter?
Schema markup is structured data added to your HTML that helps search engines understand your content. Correct schema can earn rich results in Google — like star ratings, FAQs, and product prices — which improve click-through rates.
How accurate is keyword density analysis?
Keyword density analysis identifies how often a specific term appears relative to total word count. While no hard rule exists, over-optimisation (keyword stuffing) is a ranking negative signal. Our checker helps you find the balance.
Can I use a SERP preview tool before publishing?
Yes — paste your proposed title and meta description to preview how the snippet will appear on Google desktop and mobile. This helps you catch truncation issues and improve click appeal before you publish.
