Most of the time new bloggers make this mistake. They have set their wordpress show full posts at their homepage, category pages and archive pages. It should not be the case, as this creates duplicate pages with same content on your website or blog which is powered by WordPress.
For SEO purposes and user friendliness, it should be set to show only summary or excerpts of posts at every pages except their own page or post page. That is there should be only one page at your blog or website which does have full orignal text, and all other pages should only show excerpt and link to that page.
This will help you have a great webpage with genuine content and many many internal and external incoming links to that page with anchor text in links. And this is surely going to rank your that page higher and higher for the related keywords targeted in that post.
So onward ask your webmaster or theme designer to set all home.php, index.php, category.php, arhive.php or any other template pages of WordPress theme to show only Excerpts of the posts, and only single.php, page.php show their full content. If you do want to do it yourself, look for DIY guide at my PressGold’s WordPress Blog for a detailed technical information related to this issue and fix. Also you can outsource this fix to my team at WarMarks.com if you do hate doing technical stuff yourself 🙂
