If I were to substantially re-write articles, content and so on on my site (to improve the quality of the content etc) including adding extra images with appropriate tags where there currently aren't any...
what would be the like outcome? would I lose ranking for some reason?
or when re-crawled by the Google bots would they like it and increase my scores?
what about changing titles, headers, tags and any other stuff?
I am talking about going through every post to upgrade the content to make the whole site "higher quality" in terms of it's content.
What about increasing the length of posts? They are all 300 to 500 words currently (main body of text) but what would happen if I lengthen them?
