On-page have a big impact on your website ranking. There is a big chance that your website ranking may have affected by this. You need to use your relevant keywords intelligently in title and description.

Frequent changes of meta tags will affect rankings and provide improvements only when relevant keywords are used in it.

No, but its not a good way. Once you add fresh meta title in your site then you must need to analysis the changes in the ranking results on SERP so that you can decide whether you need to change the meta title or continue with the same meta titles.
