CCBot/2.0 (


Vetrotech are pioneers in passive fire protection and high-security glazed solutions.

MintTwist were approached to support them with their International SEO efforts.

The mission

Our mission was to perform a comprehensive audit to identify the reason why the global traffic was critically low.

The website had 210 missing hreflang tags, 160 hreflang tags with errors, 273 hreflang tags with missing confirmation links, 1,108 missing x-default tags, 190 non-canonical confirmation links and 140 hreflang tags not using canonicals

Additionally we found the website had IP serving 301 redirects by default sending users to random languages. This practice affected the indexation of many pages.

Furthermore, their hreflang tags pointed to many orphan pages.

The challenge

As a consecuence of all the mentioned hreflang issues, the website had indexation issues for most of the languages but especially in Germany.

The challenge in this case was to fix all the hreflang issues for Google to better understand how the multilingual website is structured and index all the relevant pages.

The strategy

We delivered a long report with all the correct hreflang tags for all the languages.

The strategy also included the creation of language-specific sitemaps and its submission via their correspondent Google Search Console accounts.

The MintTwist team delivered the SEO results that we had always thought were possible. We will be using them on other projects soon.

The client was so happy they came to our London offices for an intensive SEO training taken by our SEO Manager. Additionally, we regularly support them with paid advertising campaigns.
