google-maps-scraper

Google maps scraper

A command line google maps parser build using

scrapemate web crawling framework.

You can use this repository either as is, or you can use it's code as a base and customize it to your needs

Maintainers wanted

Google frequentyl changes the layout of the pages and the CSS selectors needs to be adjusted and I would like some help.

Please report if the tool is broken or even better make a Pull Request with the fix.

A small request please. If you use or like the program please ⭐ the repository, it may help to find some maintainers.

Thanks

Quickstart

Using docker:

touch results.csv && docker run -v $PWD/example-queries.txt:/example-queries -v $PWD/results.csv:/results.csv gosom/google-maps-scraper -depth 1 -input /example-queries -results /results.csv

file results.csv will contain the parsed results.

On your host

(tested only on Ubuntu 22.04)

git clone https://github.com/gosom/google-maps-scraper.git
cd google-maps-scraper
go mod download
go build
./google-maps-scraper -input example-queries.txt -results restaurants-in-cyprus.csv

Be a little bit patient. In the first run it downloads required libraries.

The results are written when they arrive in the results file you specified

Command line options

try ./google-maps-scraper -h to see the command line options available:

  -c int
        concurrency (default 4)
  -cache string
        cache directory (default "cache")
  -debug
        debug
  -depth int
        max depth (default 10)
  -input string
        input file (default "stdin")
  -lang string
        language code (default "en")
  -results string
        results file (default "stdout")

-c: sets the concurrency. By default it uses half of the number of the CPUs detected

-cache: sets the cache directory (no effect for the moment)

-debug: Uses this to perform a headfull crawl (it will open a browser in your host)

-depth: is how much you allow the scraper to scroll in the search results. Experiment with that value a bit

-input: the input file with the keywords to search (see example-queries.txt)

-lang: is the language code to use for google (the hl urlparam). Default is en. For example use de for German or el for Greek.

-results: is the path to write the results

Extracted Data

• Title: the title of the business
• Category: the category of the business
• Address: the address of the business
• OpenHours: the opening hours of the business
• WebSite: the website of the business
• Phone: the phone number of the business
• PlusCode: the plus code of the business
• ReviewCount: the number of reviews for the business
• ReviewRating: the rating of the business
• Latitude: the latitude of the business
• Longtitude: the longitude of the business

Using Database Provider (postgreSQL)

For running in your local machine:

docker-compose -f docker-compose.dev.yaml up -d

The above starts a PostgreSQL contains and creates the required tables

to access db:

psql -h localhost -U postgres -d postgres

Password is postgres

Then from your host run:

go run main.go -dsn "postgres://postgres:postgres@localhost:5432/postgres" -produce -input example-queries.txt --lang el

(configure your queries and the desired language)

This will populate the table gmaps_jobs .

you may run the scraper using:

go run main.go -c 2 -depth 1 -dsn "postgres://postgres:postgres@localhost:5432/postgres"

If you have a database server and several machines you can start multiple instances of the scraper as above.

Kubernetes

You may run the scraper in a kubernetes cluster. This helps to scale it easier.

Assuming you have a kubernetes cluster and a database that is accessible from the cluster:

1. First populate the database as shown above
2. Create a deployment file scraper.deployment

apiVersion: apps/v1
kind: Deployment
metadata:
  name: google-maps-scraper
spec:
  selector:
    matchLabels:
      app: google-maps-scraper
  replicas: {NUM_OF_REPLICAS}
  template:
    metadata:
      labels:
        app: google-maps-scraper
    spec:
      containers:
      - name: google-maps-scraper
        image: gosom/google-maps-scraper:v0.9.3
        imagePullPolicy: IfNotPresent
        args: ["-c", "1", "-depth", "10", "-dsn", "postgres://{DBUSER}:{DBPASSWD@DBHOST}:{DBPORT}/{DBNAME}", "-lang", "{LANGUAGE_CODE}"]

Please replace the values or the command args accordingly

Note: Keep in mind that because the application starts a headless browser it requires CPU and memory. Use an appropriate kubernetes cluster

Perfomance

At the moment when you run it with concurrency 4 and with depth 10 it takes around:

around 30 seconds to scrape each search

and around 8 seconds to scrape each business listing

So assuming that depth 10 contains 100 listings then for each search keyword we expect: 30 + 100*8 = 330 seconds.

If we have 1000 keywords to search we expect in total: 1000 *330 = 330000 seconds ~ 92 hours ~ 4 days

If you want to scrape multiple keywords then it's better to use the Database Provider in combination with Kubernetes for convenience
