Why Google Rewrites Title Tags
Even before the update, Google would change the title tags for a better search experience.
Instead of showing webpages with title tags of Homeand Untitled, it adds meaningful and relevant titles to improve the page’s click-through rate and user experience.
With its new system, Google finds an alternative text from the page’s text that’s more relevant to the result. By making the title more relevant, Google helps users find the information they’re looking for.
Google confirmed that it uses default title tags 87% of the time. It’s the remaining 13% of titles that it rewrites.
If we understand Google’s rewrites, we can learn why Google changes title tags.
