Step-by-Step: How to Scrape Leads with KorpDeck

Prerequisites

Before starting, make sure you meet these requirements:

  • Have a registered account on KorpDeck
  • Internet access and compatible browser (Chrome / Edge)
  • Knowledge of your target niche and desired location

Log in to your KorpDeck dashboard and select the option “Search users by niche”.

Here, you’ll need to enter the following parameters:

🔍 keyword1: Your Main Topic

Define the type of profile you’re looking for.
Example: "financial advisor", "digital entrepreneur", "freelance web design".

🔍 keyword2: Secondary Filter or More Specific Location

You can use keyword2 to include a city, neighborhood, or area.
Example: "Mexico City", "Valencia", "Miami".

This helps the system prioritize leads from that region.

🌍 country: Search Country

This filter defines the general language and location context of the search.
Example: "Spain", "Colombia", "United States".

🇪🇸 lang: Display Language (Optional)

Doesn’t affect the actual language of the profiles but allows you to view results in Spanish or English, depending on your preference.

🔁 combination: Variations of Results

Each combination returns a unique set of profiles.
For example:

  • combination=1 → First set of results
  • combination=2 → Second different group
  • And so on until all results are exhausted

The number of leads returned per execution may vary, as it depends on Instagram’s internal algorithm.
