Frequently Asked Questions

Everything you need to know

You can generate and preview meta tags, create Open Graph cards, build schema markup (JSON-LD), generate QR codes, create XML sitemaps, build UTM tracking links, and analyze keyword density.

No, all SEO tools are completely free with no usage limits. Useful for freelancers, agencies, and in-house teams who need quick SEO utilities without expensive subscriptions.

Use our Meta Tag Generator & Previewer tool. Enter your title, description, and URL, and instantly see a live SERP (search engine results page) preview of how Google will display your listing.

Schema markup is structured data (JSON-LD) added to your HTML that helps search engines understand your content. It can enable rich results like star ratings, FAQs, and product details in search, improving click-through rates.

Yes. The Sitemap Generator lets you input your website URLs and generates a valid XML sitemap you can save to your server and submit to Google Search Console.

Use the Readability Checker tool. Paste your page content and it calculates your Flesch-Kincaid reading level, average sentence length, and overall readability score. Aim for a reading grade level of 7--9 for general web audiences. Simpler content tends to rank better in featured snippets and has lower bounce rates.

Open Graph (og:) tags are used by Facebook, LinkedIn, WhatsApp, and most social platforms to control how a shared link displays -- title, description, and image. Twitter Cards are Twitter's own system that does the same for Twitter/X. Most platforms now fall back to og: tags if Twitter Card tags are missing. It is good practice to include both: og: for broad compatibility and twitter: tags for correct rendering on Twitter/X.

Use the Open Graph Preview tool. Paste any live URL and it fetches the page's existing og: and Twitter Card tags, then shows a rendered preview of how the link card appears on Facebook, Twitter/X, LinkedIn, and WhatsApp. This is different from the Open Graph Generator -- the Preview tool audits an existing URL rather than generating new tags.
