If Google still shows my old title in the search results then there is no way my title change could have changed my ranking yet right?

If Google still shows my old title in the search results then there is no way my title change could have changed my ranking yet right?

In other words if I changed from TItleA to TitleB but search results and cache still show TitleA then any SERP drops or increases would still be entirely based on titleA right?

Thanks.

I wouldn't say definitely, but yes most probably it is still pulling the existing cache.

If you click on the cache, that is what google is using to index the page. You can also check Google Webmaster Tools, Fetch as Google tool, to see if your title is being picked up correctly. You can also see the frequency that google visits your site as well in Webmaster Tools.

I have had problems with Wordpress sites not being structured correctly and google pulling the wrong meta title.
