Hi Dimitrii,
There is around 20 000 domains with the same content at the moment and this number is constantly growing. There is only random variations in title and meta description currently. Each time the pages is loaded those data are changing.
We need to have the visible content on these pages more or less the same as they are now as they give useful information to clients at the same time as they market our products. We can change all content that is not visible and make those permanent on each domain (if desirable).
Given those requirements and that information, would you recommend me to put no follow on the links to our website? Is the current setup hurting our SEO efforts since it is guaranteed that extremely many of the domains has duplicate content?
Thank you so far for valuable tips.
Best regards,
Jon
