Some time ago we introduced you to the new [Macro feature](https://www.mergado.com/mergado-macros). During its testing, we have **improved** some of its **features** and **implemented** **new** **ones** with the help of our insiders. Let’s take a **quick** **look** at where it will make your work easier.

## Learn how to work with Mergado macros, you speed up a lot of work
With [macros](https://app.mergado.com/projects/105468/macros/), you can do several common tasks in Mergado. Their automation will **save you a lot of valuable time**.
[  ](https://www.mergado.com/sites/default/files/perm/paragraph-image/makra-ob1.png)
### What existing macros do:
- ### Add manufacturer to the title
It creates a query and rule that adds the manufacturer to the product name.
- ### Set values in unique URLs
It creates a single rewriting rule that ensures that **every URL is unique**.
- ### Remove HTML from tags
**It removes HTML tags**, e. g. from product descriptions.
- ### Swapping values for two tags
It **swaps the values of two tags**, typically when it is necessary to replace the main product image (e. g. IMGURL) with one that is in the feed as an alternative (e. g. IMGURL\_ALTERNATIVE).
- ### Segmentation into 10 conversion levels
It creates 10 queries to divide your products into 10 conversion levels. It assumes the active use of [Bidding Fox Elements](https://store.mergado.com/detail/biddingfoxelements/).
- ### Segmentation into 5 price levels
It creates 5 queries to divide products into 5 price levels.
- ### Hide cheap products
It creates a query and rule that hides cheap products.
- ### Hide products that are out of stock
It creates a query and rule to hide products that are not currently in stock.
