Can OG titles be used as a substitute for Meta titles

[patilhimanshu]

We use og (open graph) titles in lieu of meta titles. Is there any downside to using just one. Should we be using both og and meta titles on our page.

Appreciate any insight.

Open Graph and Meta Titles act slightly different. Open Graph is for audience on social media such as Facebook and Meta Title information can be processed by search engine bots and display results in the organic listings on search engine page such as Google.

Meta title are usually crafted by keeping the keyword search volume, target market and user interest in mind. This help with the rankings on search engines like Google.

Open Graph are usually created to serve meta title that look 'appealing' to the users on social media (Facebook) so as to receive more clicks. There are no rankings involved here.

You can have meta titles and open graph titles as the same or different, it depends on what you are after.

TL;DR - Yes, you should use both for better CTR in SERP and Social Networks.

OpenGraph is described here:
http://ogp.me/
and OG is mostly used from Facebook and G+.

Twitter used TwitterCards:

G+ used shema.org or OG:

Pinterest used RichPins:

So you should read excellent article from Cyrus Shepard about all meta tags:

where everything is described with examples.

And answer is YES! Today is 2015 and within few days will be 2016. Today shares in social networks are so much important than also baclkinging. Of course organic visits and visits from social networks are different, so you need to implement both of tags to get maximum performance there.
