16. Just click on yourname.blogspot.com to link the blog with your given domain.

17. Select yourdomain.com to given domain.com and click "Save" to complete your setup.

18. Generally it verifies the domain using the CNAME records but If you face any verification related issue such as We have not been able to verify your authority to this domain, then no need to worry about that. You can verify your ownership of the domain with a TXT record through google search console. When you will face the verification issue just read out the whole instruction and look for Google Search Console here instead. Click on here which will redirect you to google console page. Just see the both images given below and do the same showing in red mark area.
You can check CNAME records from here: CNAME records
You can also check your DNS from here: DNS lookup

From the image given below you need choss Other and you will get a TXT record to verify the ownership. Just copy the TXT record and add it to your DNS Management list. Check step 13 to review how to add records in DNS Management section. (Do not close the console tab)
Enter @ as Host Name, Choose SPF(TXT record) as Record Type, Enter the copied TXT record as Address and click Save Changes.
After adding the record in your DNS Management go to the console page again and click VERIFY (see the image)

If everything goes fine, you will see a message of complete ownership. Remember, after changing the information it will take upto 24 hours to complete the process and then your blog will become live.
Some helpful notes:
- If your new domain isn't taking you to your blog, wait another day or two to make sure all the DNS servers have been updated. If it still isn't working, contact your registrar to make sure you entered the DNS settings correctly.
- Your original Blogspot address will automatically forward to your new domain. That way, any existing links or bookmarks to your site will still work.
