How to change our design or content that users open our website when they see the content?

Maybe the title is not clear; Because the subject is a little special

We are well ranked website and our users are really important for us, and we really care about them. We even don't advertise on our website or if we do we try to do our best design for ads and they have to has harmony with the entire website's template.

We have Chrome extension and Firefox add-on for our website that users out of our website can use our service and our extension is really popular and users like it. (We know this from feedback)

recently we developed a new Chrome extension; if you search for "define computer" or "define something..." Google will define it for you, see the below image:

And we just made something like what Google return for Persian (We are a big famous dictionary and more services) and when user is searching for something in Persian or just search a word we will show them the result inside Google by our extension and they don't need to open our website anymore if they see all the result inside Google (by out extension)! This is what we return:

We'll show what user search and we have it in our database inside Google search, Then we think more than half of our extension users won't open our website. (Just about 10% of our users will install this extension) but it is still a good number of users!

We really care about our users and like to let them use this extension because this extension will really help them but the problem is we also need our ranking.

So, what we are going to do is just show half of the result and put a read more link, Show some more words that user may be interested to know what does they mean and click and open the website...

Any suggestion? Your advises would be so useful for us
