Why Title looks different on Google SERP?

Hello Team,

I don’t know if anyone observed this or not. On Google, our website’s home page title looks different for some keywords. You can check below images to understand the concept.

Keyword 1: image
Keyword 2: image

For keyword 2, it shows one of our blog’s images. Similarly, for some keywords, it shows the same image. I don’t know why Google bot fetched that.

Similarly, for one of our service pages, Google is showing an image. We didn’t upload that image on that page. Not sure where Google took that image & showing it on SERP for that service page.
