"Google Accounts can only be recovered within a short period of time after deletion. If you received an error message stating that "This account was deleted and is no longer recoverable," the account has been deleted for too long and cannot be restored by our support team.

Some common reasons people see this message include:

• Your account was disabled for perceived spamming and, because you did not sign in to verify your identity, your account was deleted.
• You intended to delete a certain product from your account but accidentally deleted your entire Google Account.
• You never owned this account, and it was deleted by the true owner.

If you accidentally deleted your Google Account, you can attempt to restore it by going to our password-assistance page within a limited window of time after deletion. If you’d like to create a new Google Account, visit our sign-up page. Note that you will be unable to reuse your old Gmail username, as Gmail usernames cannot be recreated after they've been deleted."

The short answer is no - it will have no negative impact.

Hiya Patrick,

Whilst it might seem tempting to create 10,000 back links a day ( more back links means better SERPS right ? - Nope ) this will not help you rank up in fact it will do the opposite and is more likely to have you removed from Google's results all together.

A long time ago you could get away with loads and loads of links however times have changed a lot  so maybe you saw that it was a good idea - it is no longer so.  The best way to get on-top of search results is to create good content and good content means good links. All though this take more time it will give you far better results.

You can find many good tips & tricks around here as to how to create good content that may get you good links. Please don't use an automated submitter (as seen by the horror above!)

Good luck!

I wouldn't of thought so directly as it like a log-in would need the robots to type which they don't tend to do, it may indirectly affect your SERPs via a longer loading time but again it's most likely something else, Have you checked other factors like any link building you've been doing or if you've had and referring links drop etc. ?

Have you also seen much movement in your niche? You may find someone else has other input but in my opinion if it benefits the users I'm up for it, just make sure ti doesn't affect loading time by adding crazy times etc.

Hiya,

The alternative tag is a good start but you may want to do some more reading I'll put some links below. It's easier to try to make unique content or have a structure like www.example.com/us which may be an easier short term until you've got enough content for a .com site.

I always find it nicer to formulate your own answers and learn a bit along the way so I help the above helps you do that.
