How to remove indexed pages from google?

Hello....

I have ecommerce website with hundreds of products.
Client has changed the website url structure and parmalinks of whole website.
So, if I open old indexed pages from google it shows 404 error.
I want to remove all those pages. I know there are tool in webmaster but I want to do it all in once by removing multiple websites from google.

So, can any one please help me guide how to remove multiple products from google.

 

Better solution would be to use 301 redirects. This way you will not lose the traffic.

People will click on the search result and will be automatically redirected to the new location.

 

The redirect would be the better solution, though perhaps taking advantage of your .htaccess file and putting a redirect in there for anything that matches a certain range of url strings.

 

thank you for the advice you've given, I will try redirect

 

Even if you redirect, the page will be still indexed. If the content has changed as well then I recommend using the Google Webmasters Tool to remove the whole old page.
Hope it helps!

 

You can 301 redirect all those 404 error pages to any relevant or home page, this is main solution, I would say.

 

1. Remove or take down the page – As an SEO agency we would recommend you use a 301 redirect from the removed page url to your site’s home page.

2. Download your Robots.txt file and add this line: Disallow: /"[removed url]" where the content in square brackets is the url you have removed, less YOURSITE.com.

3. Upload the modified robot.txt file to your root directory.

4. In Webmaster Tools, head to “Site Configuration” > “Crawl Access”, click on “Remove URL” and then click on the new “Removal Request” button

5. Write a quick PR which will send the crawler to the page that you want removed, using your homepage URL as the anchor text .

6. You might also want to place a link on the footer to the page to be removed, generally speeding up the process. You can use your site name as anchor text.

We have seen that Google downloads robots.txt file every hour and it checks removal requests every 2/3 hours.

We have been able to de-index pages from Google SERPs within 12 hours of initiating the above 5 action points.

 

If you want to remove your indexed links from google search result then you can use remove url option in google webmaster tool.
