Why the site title did not cached?

[aksharweb]

Hello Everyone,

I have an one problem related to the google indexing that i have mention below.

My website made in the wordpress and i set my website name as title (in wordpress general setting- ex company name). Then the google was cache that page and indexing.

Then after i created my home page and used the different title (page meta title - SERP title) for my home page but now the problem is that google SERP pages only shown my title (company name) instead of the title(SERP Title).

Note phase this problem from the last 6 month.

Any one suggest me that how can i solve the problem?
