Welcome to the Q&A Forum

_But there will be a lot of old files left that have no equal in the new site. Do I just delete these, or noindex nofollw them? _

If any of the old pages left benind have" Page Rank" ascribed to them, you might consider creating "catch all" pages on the new site so as to be able to 301 the leftover old to the new "catch all" pages and thereby reatain the link juice.

This requires creativity as you don't want to lose usability just to catch more link juice. Not knowing your exact situation I'm not positive this is an option but mention it just  incase.

Hey Sean: The official moz info on how they calculate page authority is as follows: (apologies in advance for the garbled hyperlink. It's some kinda bug either on the mozplex's side or in Opera 11.01

Hey again Francisco, upon rereading your question, it looks like I went off half cocked when I answered it. I missed that you had solved the immediate problem and that you were wondering what course of action to takke if they don't stop. the attack

If someone continues deliberately attacking your site I'm thinking the only course of action is  to change your domain name. It's not a good solution so I hope someone else chimes in with a better one.

Hey Mike: From what I read, it was a simple case of buying links and when the NYTbrought it to Matt & Co's attention, they manually delisted them.

Vanessa Fox had a great write up on it at  Search Engine Land.

Hello Francisco: Really sorry to hear bout this. Bummer!

I've never personally experienced a DDOS attack ,so  I called the web host I use to get his advice. He said that Dreamhost should be able to offer some kind of DDOS mitigation service.He seemed surprised that they weren't able to block it if it was coming in from only 20+ IP addresses.

He also said that if the attack continued, they'd probably not want the account after a certain point. He seemed surprised that they weren't able to block it if it was coming in from only 20+ IP addresses.

One of the main reasons I use him is that he's always been helpful when I've had problems. He said that he'd be willing to host you for a month to see if he could help. His company name is   TRK hosting

I've avoided answering as I don't have any new thoughts to offer Dejan, but as your Q remains unanswered I'll at least add my two bits:

If I had a client that had a dedicated PR team, I'd task them with blogging for the client as well as being the clients "voice" on social media (specifically Twitter, Facebook and LinkedIn) I'd also give them the job of tracking the clients reputation.

One last item. I'd task them with the job of bringing fresh donuts to all meetings

After rereading my answers and yours, I'm inclined to agree with you G. I interpreted the question very narrowl Most of my experience has been with sites selling things, and  the PPC used has always been to drive traffic into regular permanent pages.

I'll tell you, this Q&A is harder than I thought! I'll have to be more circumspect when I answer a question!

Hi Spencer:

I don't know if this qualifies as the easiest way , but it ranks right up there:

Hiya Craig:  This post from YOUmoz might help you to be able to wrap your mind around it better.

Hi Mike:

Keyword capitlization  makes  a difference is in the URL's. (Personally I recommend sticking to lowercase.)

As far as elsewhere on page  as far as I can tell, the search engines don't differentiate.

"Landing Pages for organic traffic are very different from Landing Pages for PPC"

While I don't disagree completely Gianluca, I'm from the camp that believes every page on a website should be treated like a Landing Page. It should be able to guide the visitor to a desired action.

The reasoning behind this is  that when a site recieves organic traffic,  there's no way to ensure that the visitors will enter your aite where you want them to enter.

That's the rationale behind my stating that PPC best practices are equally valid for organic.

Hi Derek:From the Moz manual,  "Meta refreshes do pass some link juice but are not recommended as an SEO tactic due to usability and the loss of link juice passed"

Also, some SEO's feel that Google looks askance at their use.

There's no way to talk them into a 301 redirect, huh?

Hi Mike: I'm not sure this answer will be specific enough, but it will address some of your question at least. I wouldn't separate your landing pages from your site for starters. If people end up linking to them, you want that juice to flow into your site. It will also enhance usability and enable the visitor to discover other parts of your site.

Each of your LP's should have a clear call to action. You are paying for every visitor so make sure you get your best return on your PPC spend by crafting the best LP you can, and then test. test. test them with A/B testing to optimize your  results.

While this advice holds true for PPC, it's equally valid with best practices for  organic traffic.
