Liking the whole page instead of the individual post

I have manually added FB like, Twitter and Google Plus buttons to my content.php page. However if you click one of them it likes my whole page instead of liking or sharing the post. I wanted to know if I could tweak the code I’m using to make it like the individual post instead, the code I’m using is:

<!-- AddThis Button BEGIN -->
<div class="addthis_toolbox addthis_default_style ">
<a class="addthis_button_facebook_like" fb:like:layout="button_count"></a>
<a class="addthis_button_tweet"></a>
<a class="addthis_button_google_plusone" g:plusone:size="medium"></a>
</div>
<script type="text/javascript" src="http://s7.addthis.com/js/250/addthis_widget.js#pubid=xa-4ff5c0d418c8201f"></script>
<!-- AddThis Button END -->

Any help would be greatly appreciated!
