Recently, I start my personal blogging and want to monetise my site with Google Adsense. However, I realize that a sub domain or sub site could not be approved by Google. As a result, google only approved for monetizing in your main domain.
For example: www.maomaochia.com
blog.maomaochia.com (not approved)
Due to this, I do a lot of research and try to seek for experts to answers and solve my problem. I am using WordPress Multisite for the site building. I don’t want to redesign the whole main site to the blog site that I wanted to switch to. Because this will cost a lot of time and efforts.
After a lot of testing, I’m finally turn my Multisite sub site (blog.maomaochia.com) in to primary main site (www.maomaochia.com).
This methods is switching the site content including pages, posts, users and etc. If you are facing the same problems with me, you could try this methods. Explaining on the below.
A. Learn how’s Multisite works.
1. Check the site you want to switch.
You can see my wordpress multisite primary landing page design (Maomaochia.com) and subdomain design (blog.maomaochia.com). I want to switch the whole website from blog.maomaochia.com to www.maomaochia.com.
2. Define of wp-config.php.
From the site cpanel > wp-config.php, we can see SITE_ID_CURRENT_SITE = 1, BLOG_ID_CURRENT_SITE = 1.
Go to phpMyAdmin open the database, check the file [name]_blogs, we can see the current settings blog_id are different. From here we know wordpress use this to define sub site in multisite.
*the [name] is the database name, you must find the right database of the site.
4. Options Table
Now search “options”, you can see there are few options file. Each options define sub site in your WordPress multisite.
Check the [prefix]_6_options, site url is blog.maomaochia.com.
From the above you know that, wordpress how to define every subdomain in multisite. Once you create a new site in your wordpress multisite, here will automatically generate a new file name accordingly in your database. For example 10_options, if you create 10th subsite in multisite.
B. Start switching sub site to primary site domain.
Read carefully the whole writing before you go into the process.
1. Before switching, backup your site!
You could try WordPress Backup and Migrate Plugin – Backup Guard this is a free plugin for WordPress Multisite backup. Network active and go to backups, you can choose to full backup or custom backup database or files only.
2. Duplicate both site you want to switch.

Sites > Duplicate
Choose the Original site to copy > Name new site address and title > Site admin email > Click [Duplicate]
*If you want to move your current primary site to another subdomain, name the site address to the new subdomain.
3. Edit database in phpMyAdmin.
In my case, I want to switch my blog.maomaochia.com to www.maomaochia.com.
Search and open blog.maomaochia.com options table (located in [name]_6_options in my case), edit the siteurl and home column “option_value” to “https://maomaochia.com”.
Also, editing maomaochia.com options table (located in options), edit the “option_value” to “http://blog.maomaochia.com” as below.
After edit both options table, search and go to [name]_blogs change the (maomaochia.com) to (blog.maomaochia.com) in blog_id 1 column and (blog.maomaochia.com) to (maomaochia.com) in blog_id 6 colume. Demo below.
4. Edit wp-config in file maneger.
Open wp-config.php, change the BLOG_ID_CURRENT_SITE to ‘6’ (in my case) and click [Save].
5. Transfer media.
Now we have done in server site, refresh your wp-admin and you will see your primary site have been change. However, your media become unusable but luckily we’ve already backup.
