I must appreciate the quick effects of this plugin on google search.
I have been using this plugin on my website http://www.vsagar.com since a couple of weeks but I am really impressed with its positive effects on Google search in particular.
However, I noticed slight lagging so far as Bing search is concerned, which I don't know about its technicality, which the author of this plugin may explain.
But the overall results of this plugin are just beautiful.
There is still one more point that I must add:
When used, this plugin produces one "summery" box at the bottom of each post. For me in particular, this box is not required.
I talked with the author of the plugin, and he said in his mail -
If you hide the summary box Google won't be able to read your snippet data and also it wouldn't show up in search results. Even still if you need to hide the summary box and want Google to read your data you will have to write your snippet code in meta tags.
We will be releasing a future update with an option to hide the summary box which can be also read by search engines. Stay tuned!
So I hope to get his new update as quick as possible.
I heartily thank the author/designer of this plugin and wish him best of luck for the future update.
