The Content settings under the Advanced tab when creating a source provide options to manage and streamline the content imported from your source.

Trim the Content
This option allows you to trim down the imported content for each item to a specific word count rather than importing the full content that’s available from the source.
By importing short snippets, you are reducing the potential for duplicate content and giving more credit to the original author since readers will have to go to the original site to read the full content. This could help your SEO efforts, improve user experience, and build a stronger relationship with your sources.
Limit the number of words per post
Set the maximum number of words for each imported item when trimming the content. For example, if you set this to 100 words, each item will be trimmed to that length.
Remove Unwanted Content
Streamline your imported posts by removing unnecessary elements like ads and social buttons.
Use rules known as CSS selectors to specify which elements to remove or keep. This helps in keeping the imported content clean and relevant.
When adding a new rule, you will see four options:
- Remove the matching elements: This option removes the elements that match the specified CSS selector.
- Remove the matching attributes: This option removes the attributes that match the specified CSS selector from the elements.
- Remove the matching elements, but keep their content: This option removes the elements that match the specified CSS selector but keeps their inner content.
- Remove everything except the matching elements: This option keeps only the elements that match the specified CSS selector and removes everything else.
After selecting the rule you want to use, enter the CSS selector for the elements or attributes you want to target. You’ll find these elements or attributes from the original source site. Click the Save button to save your rule.
You can also add more rules by clicking the Add rule button. There are no limits on the number of rules you can set.
