This time I need an advice from SEO experts again: I wonder if I can have exactly the same title and the same meta description on my 2 websites? The content of these 2 websites however won't be the same - it will be similar, but I will use Copyscape to make sure that the content will be unique on both websites. Can I get a penalty from Google for duplicate content for this?
If your content is going to be unique on each site I would say no. Also when it comes to title and meta descriptions, based on the limits there are probably lots of websites that have the same titles and meta tags. But I would still recommend trying to make them different.
Make sure your meta description reflects to your niche of your website and holds some description that can relate to your meta tags
Always put the right meta title and meta description that best describe in every page of your website. Duplicating metas doesn't help a lot in your site.
