# Enrich Existing Data #### **Example: Visit every profile from a list of LinkedIn profile links and save additional public information such as current job position and email address shown on the profile page** Here is the workflow set-up:

The loop is set to iterate over table rows:

*Open Link* building block points to the table column "Profile link":

The two last *Save Web Element* building blocks save job title and about me section:

**Table before run**

**Table after run**

#### Avoid visiting same profiles You should avoid visiting the same profiles. Visiting same profiles over and over slows down your TaskBot runs and data generation. And it might also trigger **anti-bot alerts**. Some websites like LinkedIn track how many profiles you visit per day and block display if you exceed those limits. So do add extra logic to avoid visiting same profiles. The example below explains how to achieve that. #### **Example: Set profile visit status to "visited" and avoid visiting same profile links by checking if status equals "visited"** Add [update-data](https://docs.zerowork.io/using-zerowork/using-building-blocks/update-data "mention") building block:

Create a new column in your table (or in your Google Sheet) and call it "Profile visit status":

Use *Update Data* building block to mark that a profile was visited like so:

Now you need to set a condition that will check if a profile has already been visited or not. Add [start-condition-and-set-condition](https://docs.zerowork.io/using-zerowork/using-building-blocks/start-condition-and-set-condition "mention") building blocks like so:

Your *Start Condition* building block points to the "Profile visit status" column:

And your *Set Condition* building block ensures that TaskBot only opens those links that have not yet been visited:

The above set-up on how to prevent your TaskBot from visiting same profile links is also demonstrated in a video tutorial: {% embed url="" %} ### Video Tutorial {% embed url="" %}
