Yes. A capable SEO company can help a website serve more than one language correctly, which is a different and more technical task than simply translating pages. A multilingual site has to tell search engines which language version exists, point each user to the version that matches their language, and avoid being treated as duplicate content. An SEO company handles those signals so each language version can rank on its own.
What multilingual SEO actually involves
Translating page text is only the visible part. The work that affects rankings happens around the content. Search engines need a clear map of every language version of every page, and they need that map to be consistent across the whole site. When the signals are missing or contradictory, search engines often show the wrong language version to a user, or pick one version and ignore the rest. An SEO company audits the current setup, identifies which of those signals are broken or absent, and puts a maintainable structure in place.
It is worth separating two related ideas. Multilingual SEO means serving the same content in different languages, for example English and Spanish. International SEO is the broader practice of targeting different countries, which can include regional variants of one language. The two overlap but are not identical, and the multilingual side has its own specific requirements.
Hreflang for language and regional variants
Hreflang is the annotation that tells a search engine which language a page is written for, and optionally which region. It is the core technical element of multilingual SEO. An SEO company implements it so that, for example, a Spanish speaker is shown the Spanish page and an English speaker is shown the English one.
Two points matter here. First, hreflang annotations must be symmetric and self-referencing. If the English page points to the Spanish page, the Spanish page must point back, and each page should also reference itself. Second, regional variants need valid codes. Spanish for Mexico and Spanish for Spain are different targets, and the language and country codes have to follow the correct standards. A common mistake is inventing codes that look reasonable but are not valid, which causes the annotation to be ignored. An SEO company knows these rules and verifies them after implementation.
URL structure and language switchers
Each language version should live at its own URL. Search engines recommend distinct URLs for each language rather than changing content based on a cookie or browser setting, because a crawler needs a stable address to index. The common structures are subdirectories such as /es/, subdomains, or separate country domains. For most businesses adding languages, a subdirectory is the practical default because it keeps everything under one domain. An SEO company recommends the structure that fits the site and that the team can maintain over time.
A language switcher lets visitors move between versions. It should be visible, should use clear labels, and ideally should not rely only on a country flag, since a flag represents a country rather than a language. An SEO company can advise on placement and labeling so the switcher helps both users and crawlers.
Translation quality and avoiding duplicate content
Raw machine translation alone is usually not enough for content meant to rank. It misses cultural nuance and, more importantly for SEO, it often misses the actual words people search for. Search behavior varies by language and region, so a direct translation of a keyword is frequently not the phrase real users type. The current standard practice is a hybrid approach: machine translation followed by human review and localization, with the most attention given to the pages that matter most, such as the homepage and key landing pages. An SEO company can run keyword research in each target language so the translated pages target real local demand.
Correct hreflang also resolves the duplicate-content concern. Properly annotated language versions are understood as alternates of one another, not as copies competing against each other.
If your site already serves more than one language, or you plan to add languages, an SEO company can audit what exists, fix the signals that are wrong, and set up a structure that lets each language version rank for its own audience.
