I have done some Paid post in some blogs and now i want to delete them. Should i delete the links, put them on no follow or just delete blog post. Will Google rank me down since some post in WP is missing? The posts i am thinking of deleting is the post that does not have anything to do with my blog subject.
If they are not related to the topic of your blog, just delete the entire post. You won't have any problems to your whole blog, but if people search for the post via Google it will not show up. What you can do is just nofollow the links, this is safer and if you do this you will not have any penalty.
There will be no penalty. It'd be good if you delete them. It'll be like an editing job and google will index it again. Delete it without any worries. I had to do it lately because of some reason and it proved good only.
I think nofollow tag can do the job. You can also delete the posts (but, I think advertisers paid you to keep the posts for lifetime).
Some do PPP have that rule some have for 30 days. Its diffrent so i will follow that rules that apply for each post.
