Engines use example

To get results from all supported engines you need to use the app with no engine argument:

seo get <search  query>
Enter fullscreen mode Exit fullscreen mode

If you want to get results from one or two selected engines you need to define the --engine option (or short: -e) divided by a comma, e.g. paa, ac (People also ask and Autocomplete):

seo get <search  query> -e <engine(s)>
Enter fullscreen mode Exit fullscreen mode
  • paa - People Also Ask engine;
  • rs - Related Searches (People Also Search) engine;
  • ac - Autocomplete engine.

Use different Google domain, country and language

You can change the default google domain google.com to any of supported domains list by defining the --domain (-d) option:

seo get <search  query> -d <google domain>
Enter fullscreen mode Exit fullscreen mode

Also, you can change the default country us (United States) of the search using the --country (-gl) option and set it to any of supported country codes list:

seo get <search  query> -gl <country code>
Enter fullscreen mode Exit fullscreen mode

If you want to change the default language en (English) of the search, you need to use the --language (-hl) option and set it to any of supported language codes list:

seo get <search  query> -hl <language code>
Enter fullscreen mode Exit fullscreen mode

Available file types to save search results

The default file type to save search results is json. You can change it to txt or csv using the --type (-ft) option:

seo get <search  query> -ft <file type>
Enter fullscreen mode Exit fullscreen mode

What is the depth parameter? (only for People Also Ask results)

When you open People Also Ask result, it loads more results:

  • Default:

image

  • One of the results is open:

image

So if you open all initial results that was mean you see next-depth results.

The depth limit parameter can be set from 1 to 3. This limit is set because, for each depth value, the number of results returned grows exponentially, for example, if the number of results is 5 at each level, for a depth of 3, the total number of results will be equal 125.
