To set different languages for different spiders on a website, you need to make use of the "Accept-Language" header in HTTP requests. The header indicates the preferred languages of the client, and the server can use that information to serve content in the best-matching language.
Here's an example implementation in Python using the Flask framework:
1 2 3 4 5 6 7 8 9 10 11 12 |
from flask import Flask, request app = Flask(__name__) @app.route("/") def index(): language = request.headers.get("Accept-Language") if language.startswith("en"): return "English content" elif language.startswith("fr"): return "Contenu en français" else: return "Default content" |
In this example, the server checks the Accept-Language header in the incoming request, and returns content in English, French, or the default language, based on the header value. Spiders can set the Accept-Language header in their requests to indicate their preferred language.

To set different languages for different spiders on a website, you can use the following steps:
- Set the language in the HTTP header: You can specify the language in the "Content-Language" header of the HTTP response. For example, you can use "Content-Language: en" for English and "Content-Language: fr" for French.
- Use hreflang: The hreflang attribute specifies the language and geographical target of a webpage. For example, you can use <link rel="alternate" hreflang="en-US" href="http://example.com/en-us/" /> for an English page targeting users in the US and <link rel="alternate" hreflang="fr-FR" href="http://example.com/fr-fr/" /> for a French page targeting users in France.
- Use language tags in the HTML: You can use language tags in the HTML code to specify the language of the content. For example, you can use <html lang="en"> for English and <html lang="fr"> for French.
- Serve different URLs for different languages: You can serve different URLs for different languages by using separate subdirectories or subdomains. For example, you can use "http://example.com/en/" for English and "http://example.com/fr/" for French.
It's important to note that different search engines may have different preferences and requirements, so it's a good idea to consult their guidelines to ensure that your website is properly optimized for each spider.

To set different languages for different spiders on a website, you can follow these steps:
- Define the language for each page or section of your website using the HTML lang attribute, for example: <html lang="en"> for English, <html lang="fr"> for French, etc.
- Use the HTTP Content-Language header to specify the language of the content in each HTTP response.
- In your web server or application code, use logic to determine the language of each request based on the user-agent string of the spider making the request.
- Set the appropriate lang attribute and Content-Language header based on the determined language.
Note: It's important to keep in mind that not all spiders respect the lang attribute or Content-Language header, and some may ignore them entirely. It's a good practice to also include language information in your URLs or in the metadata of your pages to make sure the language information is visible to all spiders.
