I bought a script for my bux site that is Extremely similar to another site. Almost an exact clone. My site is uxbux.com and the real site is bux3.com. will google ban my site from their search engines??
A duplicate content penalty is applied by Google and possibly other search engines when content found on your website is largely the same as what is found elsewhere on your site or on other websites across the internet.
Once a Google bot indexed a site, any other site that is similar to it is more likely to be denied and will not be indexed. You should ensure that you have unique content before you let SE bots see your site.
Since it is almost an exact clone of the other site, it is possible Google see it as a duplicate content. You need to change lot of thing from the new script, to make it different from the other one.
