I tried to search for it but couldn't really find the answer. It might be a stupid question but I'm still curious if anyone can help me out. I have an ecommerce site and just rewrote all my descriptions and added some other info, I wrote it all in the last two days and I have about 100 pages on the site and wrote about 100 new words for each average on a separate document. I plan to throw it all on tomorrow but if google checks me out and everything is changed and it has a ton of new content at once from last time is there some sort of penalty? It is all on existing pages already but I know that's why people usually spread out blog posts but I wasn't sure if I should spread it out over like a week or so or is there no problem of me doing it all at once. Thanks.
