So I have in the past done this a few times, but have not done it recently, but I have talked to many others who have done it. Have you ever leveraged your archives?

By this I mean:

• Have you ever backdated a post you wanted to make but for some reason did not make it when you should have?
• Have you ever fixed old post errors? Did you cite the error corrections you made or just make them? Is it required to record / mention what you changed?
• Have you ever create a test page in the archives to see how search engines would react to a new page on that topic? For example I have known some well known bloggers who put mesothelioma pages in their archives to test link bombing.
• Some people show time sensitive ads. Is it ok to post affiliate links in blog posts? Need they be disclosed? Is it wrong to change old links in high ranking posts that could make you decent money if they were affiliate links instead of direct links?
• Have you ever went back into an old post and edited out links to sites that became spammy or added links to sites you were working with?

Some people push blogger ethics, etc…but sometimes the content and ideas that sell are not the same ideas that regular readers would be interested in citing or reading. For example, if I had a few thousand SEO 101 pages on my SEO blog they would probably convert exceptionally well, but nobody would want to read about the same stuff over and over again. What would be the best way to introduce that content without offending regular readers who already knew a lot?

Should all new blog content come in through the home page? If so, why?
