# Using embedded SKUs to generate Product hotspots
***Available in Enterprise***
Publitas can automatically tag the SKUs it detects in your publications. It does so by scanning the pages and looking for matches with the SKUs in your product feed. For every match, a Product hotspot is created on top of the corresponding SKU.

### Prerequisites
To use the *Auto-tag SKUs* feature, you need to:
- Import your product data by [connecting your product feed](https://support.publitas.com/product-feed-integration?hsLang=en)[to Publitas](https://support.publitas.com/hc/en-us/articles/360016773739?hsLang=en)
- Store the SKUs in the product feed:
\- XML: Store the SKUs in the ***\*** attribute
\- TSV: Store the SKUs in the ***id*** column
- Add the SKUs to the pages of your publication in a way that they can be indexed ([Find out more about indexable content here](https://support.publitas.com/optimizing-online-publications-for-search-engines-seo?hsLang=en))
- Per product, the SKU in both the product feed and the PDF needs to be identical
*TIP: Avoid appending additional characters to the SKU in the PDF, like a dot, comma or parenthesis*
### How to automatically tag SKUs
The option to *Auto-tag SKUs* is available when uploading a new PDF to Publitas, in the hotspot editor and when you save changes in the Page Manager. Each time auto-tagging is used, it can automatically produce up to 5000 products. More hotspots can be added by manually or by running the process again.
Since auto-tagging relies on the SKUs being available in both the PDF and the product feed, it is most effective when all, or the majority, of the products are found in the product feed. However, in the hotspot editor, you can always run auto-tagging again to fill in the blanks after your feed has been updated.
### Auto-tag SKUs when uploading a new PDF
If your collection of products does not change very often you can enable auto-tagging as soon as upload the publication to Publitas. It will automatically create Product hotspots based on matching SKUs. You can additionally choose if icons should be shown for each hotspot or not.
*Locating the auto-tagging option when uploading a new PDF:*
### (Re)Run auto-tagging in the hotspot editor
Use the option in the editor, located in the upper left corner, to apply auto-tagging to your publication if you haven't done so already when creating the publication.
*Example:*
**
This option can also be used if you have already run auto-tagging before, but your feed has since been updated to include the SKUs that were missing before. Publitas will then only add product hotspots to the SKUs that don’t already have product hotspots associated with them. You can additionally choose if icons should be shown for each hotspot or not.
### Adjusting the hotspot size and positioning the hotspot icons
In the editor, look for SKUs on the pages and drag one of the corners of the hotspot to adjust the size. If you're adjusting the hotspots to cover the entire promotion, we recommend also to also [reposition the icons](https://support.publitas.com/applying-and-positioning-hotspot-icons-optimally?hsLang=en) to help increase the clickthrough.
