I want to change my page id of wordpress blog? for eg. - my page id is : - www.mysite.com/?p=9 but i want to change ww.mysite.com/?p=8 because there is no page with this(ww.mysite.com?p=8) id..
That's not important for your blog/site. But u still can change the page id over the Phpmyadmin page.
I would just add a 301 redirect into my htaccess file. In the root of your wordpress web site, there is a file called .htacess. 1. Download the file to your local machine. 2. Open the file in notepad. 3. Add the code below to it 4. Reupload the file to the root of your site
Page ID is automatically generated and you can change the url structure in any way you want except the ID of page. If you still want to change the ID of the page (and you said that ID = 8 is available ) the only way to do that is to make the changes in the database. Also i dont think there are plugins to do that.
Why not change the permalink sdetting over to words instead of ids. This is better for ranking and is prettier too.
Yes, I agree with this totally. Unless you have a specific reason for using page id's in your url's, then you should really consider switching to a custom url structure for your permalinks. It increases your chance of ranking for your keyword and as adbox said, its prettier.
Please visit https://codex.wordpress.org/Database_Description#Table:_wp_posts ID is the column that holds id for page/posts. You can change post id from changing it in table using phpmyadmin.
When you change the ID of page make sure there is no duplicate id in the database. As I can see your mentioned page id 8 don't exist. That should be fine. You can change from PHPmyadmin
