Google constantly collects additional data about your pages. It views how users react to them. It sees if users use the rear button to come back to Google after viewing your content.
It sees if the page attracts external links. Older pages have far more history; those with positive history will rank well.

Google may try it out on the primary page of the results to ascertain how users react to that. It always doesn’t stay there unless it gets a very positive click-through rate. After the test, it’s going to fall in rankings substantially, often back several pages. It could take it years to urge back to the primary page of search results.
You may even be experiencing a traffic boost two to four weeks into posting the article because of Google determining its ranking value based on the signals it’s received.
If your page has initially received a low amount of traffic, there aren’t many signals for Google to work out how beneficial this page is going to be to its users.
Once you have got started to receive some traffic then Google can analyze metrics of the article like “time on page”, “bounce rate”, “Pages per session”, etc, also as its success on social network sharing. If your article performs well in its metrics analysis, then Google will begin sending you more traffic.

Although Google prefers fresh content, an older page that’s regularly updated may outperform a more recent page.
