I have a website which is considered duplicate contents by google. actully there are more than 200 posts copied exactlly from wikipedia and caused my website to rank low.
I read several articles and find out I must use rel="canonical" but I dont know how and where to use it.
this is what google says :
Add a <link> element with the attribute rel="canonical" to the <head> section of these pages:
<link rel="canonical" href="https://blog.example.com/dresses/green-dresses-are-awesome" />Click to expand...
where should i put the links?
should I link to wikipedia ?
I am using wordpress .
and one more question, my robots.txt is :
sitemap links also included in robots.text
but I have a couple of my pages blocked.
could anyone help me to solve these issues ?
thanks in advance
