Importance and usage of social network sites in terms of SEO:
Its very important to use social network sites or social media for the advertisment and getting the word out about your website. It has great importance for seo for wordpress
I use two very useful websites for all of my postings to appear in all major social network sites.
Visit dlvr.it and sign up there. After signing up, on the left column add your website and on the right side add social networks like facebook,twitter,tbmlr,linkedin and myspace etc.
This is one simple technique which normally brings 100′s of visitors per day, depending upon your post content and how much the viewer gets excited after looking at your post.
I will also recommend you to make a free facebook page. The more people will like it, the more the word will spread.
Use of Social sharing buttons:
I would highly prefer using s e x y bookmarks plugins. It gives the visitors to share your content on the social network they are using e.g. digg, delicious etc.
Another social networking tool:
I found a very good way to add the share buttons on the website in one step, visit addthis and register there, after registering you can get the code which you can simply copy and paste to your website’s html code.
Or else if you have already logged in to blogger.com and then made an account with “addthis”, it will give you an option to automatically add the widget to your blogger site.
Why Social sharing buttons are important:
A website without sharing buttons is considered zero, because you are not giving any viewer the option to share your valuable content, in other words, you are not letting others spread your website’s content.
You should always place the sharing links on your website, its one of the key techniques to get traffic.
For my wordpress blog I personally use WP Socializer plugin. Install it and then activate it. While editing it activate or apply the theme of buttons you want to display and the sharing buttons will appear with all of your posts. Other social plugins are lazy buttons and hupso which I highly recommend.
