Cách trích xuất dữ liệu từ Google Maps: Hướng dẫn từng bước

Sometimes Google adds other categories to your searches. For example, when you search for restaurants you might see bars, coffee shops, etc.

Outscraper provides you with two tools that you can use to eliminate those categories.

1. Use the “Quote categories” checkbox. The categories will be enclosed between quotation marks ” “. The ” “ operator is typically used when you want Google to return only those companies that match your category terms exactly.
2. Filter results by applying filters to the extraction task. To avoid empty results, make sure you are familiar with the values of the fields before using filters with the “contains” operator.

2. Results filters

There are some cases when predefined locations or/and categories aren’t enough. Use the “Custom locations” or/and “Custom categories” options to insert the categories or/and locations you need.

There is a limitation from Google Maps that shows only up to 400-500 places per one query search. This may be a problem when there are more companies in one category. For example, for the query “restaurants, Brooklyn”.

To overcome this we suggest splitting the location into sub-locations. For example, by using postal codes:
”restaurants, Brooklyn 11203”,
”restaurants, Brooklyn 11211”,
”restaurants, Brooklyn 11215”,

…

Or using queries with sub-categories:

“Asian restaurants, Brooklyn”,

“Italian restaurants, Brooklyn”,

“Mexican restaurants, Brooklyn”,

…

Check the “Use queries” switcher and enter the queries.

To force Google to search for particular companies only, enclose the term between quotation marks ” “. The ” “ operator is typically used around stop words (words that Google would otherwise ignore) or when you want Google to return only those pages that match your search terms exactly.

After clicking the button “Extract data…” you will see the task estimate and the queries.

It’s recommended to click and open a few queries to check how it looks on the Google Maps site.

There are two things you should follow to control the expected number of results.

1. Organizations per query limit – the limit of organizations to take from one query.

2. Number of queries – the number of search queries you’re going to make.

There are 6 queries the bot will make to extract the data from 2 categories and 3 locations.

Therefore, the resulting amount will be no more than 480 organizations (limit of 80 * 6 queries).

You can remove duplicates in one task by selecting the “Drop duplicates” checkbox.

Yes, you can drop duplicates by using the “Drop duplicates” checkbox (advanced parameters). Alternatively, you can drop it by yourself by using the “google_id” or “place_id” fields as unique identifiers for a place.

The exact number of results will be known only after the extraction.

You can use “Total places limit” to limit the final amount of results scraped.

Yes. You can use the following link as a query “https://www.google.com/maps/search/real+estate+agency/@41.4034,2.1718413,17z” where you can specify a query (real+estate+agency), the coordinates (41.4034,2.1718413) and zoom level (17z). You can find these values while visiting Google Maps.

Alternatively, you can use the “coordinates” parameter if you are using API.
