My website had only one page (the homepage) I build a bunch of editorial backlinks to it, all legit, all white hat website moved to page 3 then, I added 20 more pages to the site, expecting it to move up because google hates one-page sites. but no, it went to page 8. do you have any idea why this would happen? the 20 additional pages are 100% handwritten and not duplicate, but they don't add any value to the site, they basically say the same thing the homepage says but in different words. could I have gotten a thin content penalty? or is this all the coincidence and the website was going to move to page 8 even if I hadn't added the additional pages? if i add the website to webmaster tools (so that i can find out if there have been any manual actions), could just adding the website to webmaster tools cause a penalty?
