# About the SEO Tags API

The SEO Tags API allows you to generate and resolve SEO tags for a site based on site and page specific metadata. The API takes a page URL and specific content information and returns a complete set of SEO tags, such as meta tags, Open Graph data, and structured data (JSON-LD). The API generates these SEO tags dynamically in real time when a site visitor accesses a page. This enables you to personalize SEO content based on site visitor preferences or update product availability and pricing information dynamically.

With the SEO Tags API, you can:

- Generate optimized SEO tags for Wix product items and static pages.
- Retrieve SEO tags including HTML meta tags, Open Graph data, and structured data to create personalized site experiences where SEO tags adapt based on site visitor preferences and behavior.

# SEO Tags Service: Sample Flows

This article presents possible use cases and corresponding sample flows that you can support. This can be a helpful jumping off point as you plan your implementation.

## Generate dynamic SEO tags for product pages

You can generate dynamic, real-time SEO tags for Wix product pages that reflect product availability and pricing. Retrieve SEO tags when a site visitor accesses a product page to enable personalized content based on the product state.

To generate dynamic SEO tags for product pages:

1. When a site visitor navigates to a Wix product page URL (for example, `"https://store.com/products/air-jordan-1"`), call the [Resolve Item SEO Tags](fallback::https://dev.wix.com/docs/api-reference/site/viewer/seo-tags/resolve-item-seo-tags) method, specifying the full canonical URL, item type, and product slug to retrieve product-specific SEO tags. The method's response includes SEO tags: title, meta description, Open Graph tags, canonical links, and structured data.

2. Inject the SEO tags from the method response into the product page's HTML head section and serve the complete page to the site visitor. The service dynamically generates the tags based on the product state, ensuring search engines and social media platforms receive accurate information about price, availability, and reviews.
