Understanding the Purpose of Hreflang

There seems to be persistent confusion about the purpose of using hreflang on your website and what it does and does not do. In this post, I will explain the purpose and why it is more critical to implement correctly than most global website owners understand.

Google’s Purpose of Hreflang

Hreflang elements were introduced by Google and adopted by other search engines as a method for site owners to explicitly state the language or language region of a specific webpage AND indicate that a URL has one or more equivalent (alternate) URLs with similar content but designated for another specific language or language region. This paraphrases Google’s guidelines for managing international versions of a website.

Why Do Websites Need it?

For the same reason, Google says we do. Many multinationals will create websites for a specific market and especially with B2B sites; the only difference is the lead form and local contact details. B2C websites typically have more unique elements like colors, sizes, prices, offers, and shopping carts tuned for the local market.

Let me try to illustrate what hreflang does using Nike.com. Nike’s country selector lists 78 market-specific websites across five geographic regions, of which 37 are in English and 22 use the $ symbol for currancy. All English language market websites use the nike.com global top-level domain with a two-letter folder representing the market. For example, Australia is https://www.nike.com/au/.

Without hreflang, Nike is at the mercy of Google to figure everything out. True, Google can quickly determine whether the page is in English, but are there strong enough signals on each to ensure Nike’s desired version in the correct search results for that market or will Google consider it a duplicate and suppress it from the results?

That is a lot of processing effort with little to no benefit to Google when they only need to show the searcher any English language version of the desired product page. Nike hopes that the page is the correct/desired website for that market.

The Nike Germany link on the selector takes a user to https://www.nike.com/de/. Does the de folder indicate Germany as the country or German the language?

Very simply, websites using hreflang removes chance, minimizes effort by Google, and remove ambiguity related to where a webpage is targeting.

Benefits of Hreflang

As the purpose illudes, hreflang offers two key benefits to a site owner.

Benefit #1 – Minimize Search Engine Results Page (SERPS) cannibalization. Since the website owner has specifically indicated a page was for the UK or France, Google will typically show that designated URL version over another it believes is also relevant. Presenting the correct market version in the SERPS maximizes traffic to the appropriate local market website, reduces shopping cart abandonment, and, ultimately, increases revenue. 

Benefit #2 – Prevent duplicate content challenges. Since the site owner has explicitly listed alternative URL versions, these near-match pages being designated alternate market versions eliminate the potential for them to be considered duplicates and demoted or not added to the Search results.

You can review our post on Why Google Needs to support hreflang to understand the importance of the website owner self-designating a market for each URL.

What Hreflang Does Not Do

Hreflang elements are not magic or a special technique to help you rank better. Unfortunately, just because you set a hreflang does not mean that search engines will use it as an absolute fact. If Google’s algorithm truly believes a page from another market is the best, it may still show it with or above the market page especially if the desired page does not have related content or words. Additionally, incorrect implementation and significant search health issues with your website can negatively impact the effectiveness of how well hreflang performs.

It does not make you rank better.

Using hreflang elements does not in itself make you rank better.  Hreflang will not increase your rank in a market where an alternate page ranks. It will only replace which page is ranking in a market at the same position. Another common myth is that if you have a single language website and then use hreflang to target other markets with that same website, it will then force the same rank in those markets. If the original site was not ranking as a global English site, is it not likely to rank trying to fool Google by saying it is now a UK or Australian Website.

Does not fix errors in SEO Diagnostic Tools

Hreflang lang elements, no matter the method implemented, cannot fix duplicate issues in SEO diagnostic tools. We have received several support tickets wanting to know why, after deploying hreflang that their diagnostic tools were still showing elements as duplicates. While hreflang gives the page a purpose, it does not and cannot magically make element-specific duplication disappear.

Does not remove another market from SERPS

Hreflang does not remove non-market pages from SERPS in another market.  For example, if your US page was ranking #1 in Ireland and you implemented hreflang, the US page may not disappear. Once Google understands your hreflang settings and the link to the alternate Ireland English version, its systems will replace the US page with the Ireland page. It may not remove the US page from the results but will demote it to a position below the Ireland page. This is especially true where one page is algorithmically dominant and/or gets a lot of traffic, Google may show it as indented but will typically be placed under the designated market version of the page.  

It does not Exclude Markets from SERPS

You cannot exclude markets using hreflang.  For example, suppose you do not want to target English speakers in Fiji due to high shipping costs. You cannot use hreflang elements to prevent being shown in Fiji since you set your website to Australian English. No provision in the rules can exclude it from appearing in any market.
