@armenhex We understand that you are intending on changing the domain name on your site, and we’ve identified several concerns in your message and responded to each below:
whether i should again write all keywords
If you are only changing the domain name of the site, but the site’s content is remaining the same, you typically would not need to edit the focus keyphrases of it’s pages.
in new domain i will have all keywords already done in bizrating.online
If you are only changing the domain name of the site, all of the site’s content should remain the same.
I mean can i export and import focus keyphrases from old to new plugin ( in new website )?
The premium version of Yoast SEO does include a feature that allows you to export the site’s focus keyphrases to a .csv file, along with the other associated data you selected in the export options. You can then view the .csv file in a spreadsheet editor such as Microsoft Excel for example.
We also have more information on exporting keyphrases in the following article: https://yoast.com/why-and-how-to-export-your-focus-keyphrases-with-yoast-seo-premium/
