If you're bilingual, you may wonder if posting in different languages will hurt your SEO efforts. You may multiple options for creating sites for visitors from other countries or visitors who speak another language; such as a Spanish speaking individuals who live in the U.S. If you just want one post on your website in another language, it won't affect your SEO.
If you're not sure if your visitors would appreciate bilingual content, it may be better to have two blogs, one for each language. This way you could get a generic top level domain for your U.S. website and a country-code top level domain for your other sites if you are allowed to buy one. Each site should have unique content and images specific to the region. This is the best option according to SEO experts, but also the most expensive and technically challenging one.
If you want to target users in multiple countries, consider using subdomains such as es.yourwebsite.com. Subdomains don't inherit SEO from your main site. You can also use subdirectories. Subdirectories inherit SEO from the main site and they're trackable in Google Analytics and Google's Search Console. Major brands, like HP and Apple, use subdirectories.
While the Google Translate widget isn't available anymore, there are paid services like Translate This Website tool. This and currency conversion tools are the easist way to go as you won't need to create new sites in subdirectories or subdomains.
No matter which option you select, Google says it does not punish webmasters with duplicate content in multiple languages, but it's always a good idea to change content to include local keywords. You should have a native speaker review and or alter the content to account the cultural differences and to avoid using words that have different meanings in different languages.
