Title Tag SEO

Google and the history of your pages

All SEOs know that the Title tag is one of the most important criteria in the web page ranking algorithm. It is for this reason that we must take good care of it, and make it evolve according to the key expressions that we seek to dominate in the SERPs.

Update the TITLE tag

The websites change over time …

  • they cover a wider theme
  • they specialize in a niche/niches
  • they refine and optimize their visibility strategy on their core theme/competence.

It is, among other things, for these reasons that we sometimes have to change our title tags, over time, over the news, and changes in mores or information landscapes. Only, this is not an innocent change.

We all know that, even if our pages are indexed in 5 minutes, the titles in the SERPs are not (yet?) Updated in real-time, and therefore we can keep the old title for several days in the results pages.

So far nothing new, but it is good to note the latency time between two updates to better understand the rest …

A history of titles, pages?

I have seen some strange phenomena in the search results for a few key phrases that I was checking… For websites I was involved with, I had changed the title tag to a variation of the expression.

The first phrase was “Monitor your link exchanges” and a few months later I changed that phrase to “Check your link exchanges”.

A few months (again) later, I check the positioning of my site in the search results, on the two expressions, and there, I notice that the titles are modified …

The old title tag appears when it has been modified several months ago. So, for the same page, Google displays 2 different titles in its results!

what then? I don’t believe it, not after several months …

Partial restoration of their index? It seems unlikely to me … Obviously, Google would therefore keep a record of what our sites were several months ago so as to easily trace changes.

This facilitates block analyzes (isolation of the menu, the footer, etc.) but it also makes it possible to observe redesigns, or even to track down updates to articles.

So you might think that there would be multiple indexes or rather a historical index that would also be queried for a certain period of time after changes have been made to the site.

The next question is “Did this have an impact on my positioning? The answer is no, at least not in my example. If others have encountered this phenomenon, I would love to hear from them.

On the other hand, the positive point is that it allows you to use the exact phrase you are looking for when it matches the title of the page, so it encourages the visitor to click more since that is the phrase they are looking for.
A month after this observation, the phenomenon disappeared …
