I decided to spruce up a few older pages by adding some new content to them and they fell out of Google and now get no traffic from Google but Bing and Yahoo figures remain unchanged, any ideas why?
- No url changes
- No redirects
- No template changes
- No changes to anything in the head section or robots.txt or to anything else
- Only original and useful textual content was added
result: no traffic and not ranked at all for their titles(which were not changed either)
- Does changing content on an older page (6 years old) cause old signals to be refreshed/ignored?
- Could it be that all incoming link value has been snipped due to changes?
If it's the second option, which Matt Cutts talks about in a youtube video on picking up dropped domains, would removing the new content help? (old content was not changed).
The theory would be: Sites voted for my pages in the past with a link but now that the pages have changed the link is no longer a vote for the new content, it was a vote for the old content, and thus is no longer helping?
I've seen pages/sites fall out of serps during migrations, i've migrated sites many times myself, but have not seen pages fall out of serps for having a few paragraphs of useful original text added before. Thoughts?
