Technical SEO Generator
Generate production-ready technical SEO tags instantly. Canonical, hreflang, robots, Open Graph, Twitter Cards, and more — with live preview, validation scoring, and one-click export.
Master Technical SEO in Minutes
Technical SEO forms the invisible backbone of every high-performing website. While content drives engagement, it is the meta tags, canonical URLs, and structured directives that tell search engines how to crawl, index, and display your pages. Getting these right is the difference between ranking on page one and being lost in the void.
Our Technical SEO Generator eliminates the guesswork. Instead of hand-writing HTML tags and wondering if you missed a closing quote, configure your settings visually and get production-ready code instantly — validated, scored, and ready to paste into your <head> section.

Tag Reference Guide
Every checkbox and toggle in the tool maps to a specific HTML tag. Here is a quick reference of what each option generates:
| Section | Option | Generated Tag | Purpose |
|---|---|---|---|
| Canonical | Page URL | <link rel="canonical"> | Prevents duplicate content issues |
| Robots | index / follow | <meta name="robots"> | Controls crawling & indexing |
| Robots | noarchive | noarchive directive | Blocks cached page in search results |
| Robots | nosnippet | nosnippet directive | Removes text snippet from results |
| Robots | max-snippet | max-snippet:N directive | Limits snippet length in characters |
| Hreflang | Language rows | <link rel="alternate" hreflang> | Targets specific language audiences |
| Hreflang | x-default | hreflang="x-default" | Fallback for unmatched languages |
| Open Graph | Title / Desc / Image | <meta property="og:*"> | Social sharing preview on Facebook, LinkedIn |
| Card type | <meta name="twitter:card"> | Preview style on Twitter/X | |
| Pagination | Prev / Next URLs | <link rel="prev/next"> | Signals paginated content series |
| Viewport | width / scale | <meta name="viewport"> | Mobile-friendly rendering |
| Additional | Theme color | <meta name="theme-color"> | Browser UI color on mobile |
Industry Use Cases
Technical SEO tags are essential across every type of website:
- Blog & Content Sites: Canonical tags prevent duplicate content from tag pages, archives, and pagination. Proper robots directives keep thin pages out of the index while keeping valuable content crawlable.
- E-commerce Stores: Product pages often have multiple URLs due to filters and sorting. Canonical tags consolidate ranking signals. Open Graph tags ensure products look great when shared on social media.
- Multilingual Websites: Hreflang tags are critical for serving the right language version to the right audience. Misconfigured hreflang can cause entire language versions to be deindexed.
- Landing Pages: Twitter Cards and Open Graph tags maximize click-through rates from social shares. Viewport tags ensure mobile-first compliance for Google's mobile-first indexing.
- SaaS & Web Apps: Robots directives can prevent crawling of authenticated areas, admin panels, and API endpoints while keeping public marketing pages fully indexed.
Self-Referencing Canonicals
Every page should have a canonical tag, even if it points to itself. This protects against URL parameter variants and ensures clear indexing signals.
Hreflang Reciprocity
Hreflang tags must be reciprocal — if page A references page B, page B must reference page A. Use our tool to generate consistent tags for all versions.
OG Image Dimensions
For best results, use 1200x630px images for Open Graph. Twitter Cards work best at 1200x600px for summary_large_image.
Avoid noindex + nofollow
Using both together blocks the page from indexing AND prevents link equity flow. Usually noindex, follow is a better choice — it blocks the page but passes link value.
