Free seo tools that run entirely in your browser.
The SEO Tools hub is the technical side of getting found: the tags, files, and structured data search engines read before they decide how to show your page. Generate Open Graph and Twitter Card meta tags that control link previews, build robots.txt crawl rules, produce XML sitemaps, and declare canonical URLs to stop duplicate-content confusion. For rich results, create FAQ, breadcrumb, article, and product JSON-LD schema, plus the web manifest that makes your site installable. Every generator runs in your browser — paste your values, copy the finished snippet into your page head, and nothing is uploaded.
What is a meta tag generator?
It creates the HTML meta tags (title, description, keywords, robots, canonical) needed to optimize a page for search engines.
What are Open Graph tags?
Open Graph meta tags control how a page appears when shared on Facebook, WhatsApp, LinkedIn and other platforms.
What size should the og:image be?
Most platforms prefer a 1200×630 image (1.91:1 aspect ratio). It renders crisply on Facebook, WhatsApp, and LinkedIn and avoids the low-quality scaling you get with a smaller or portrait crop.
Do Open Graph tags help with search rankings?
They do not change ranking directly, but consistent rich previews raise click-through from social shares, and the engagement that follows is a positive signal. Add them alongside normal SEO meta tags.
