Hi,

We were using them in the past especially for their organic rank checker. Even though it's not accurate , it gives you an idea for what keywords a site is ranking for. (You can use other tools to check the accurate ranks for those keywords)

The cancellation was pretty straight forward. We just sent an email and stopped getting billed the next month. We have since signed back with them. Did you try reaching out to them at this # on the link below?

Hi Sorina,

Archiving is more about classifying information/content that is either outdated or not being accessed that frequently by the visitors into a separate section on your site. I would not no index those pages because they might be ranking well in the search engines and still be getting traffic to the site. You can do this creating an "archives" section on your site so that if the visitors want to access the old content on your site they can still do so by accessing that section.

Here is a useful post on archiving content on your site

Hi Joe,

Welcome to the community.

In my opinion, be very careful of using this plugin especially with Google going aggressive with their over optimization penalty. It does not look very aesthetically appealing to have visitors looking at a bunch of search terms at the end of your blog posts.
