I've read that you can use Screaming Frog to identify orphan pages on your site, but I can't figure out how to do it.  Can anyone help? I know that Xenu Link Sleuth works but I'm on a Mac so that's not an option for me. Or are there other ways to identify orphan pages?

After reading this on the SEOMoz blog, I've decided to try some guest posting to gain some backlinks for our real estate site.  I have a few questions for those of you who do this regularly: 1. If the site you are posting on allows up to 3 links in the signature box, do you generally use them all?  My gut instinct is that one anchor texted link would give me the most bang for my buck. 3.  How much attention do you pay to PR or DA?  If a site is PR1 but relevant to your niche would you spend the time to write the article? 4. What negatives have you found when writing guest posts? Thanks!

I will often post photos that I have taken to my Facebook page (either personal or my fan page).  Sometimes these can get lots of likes. I got thinking that perhaps I host these photos on my site (i.e. www.example.com/images/photo1.jpg) and then share that "page" on Facebook.  That way any of the likes would be counted towards my site. What do you guys think?

It's just a theory, but I think that Panda was not really an algorithm update but rather a conspiracy. Google went out of their way to announce that a new algorithm was being rolled out.  The word on the street was that content farms would be affected.  Low quality sites would be affected.  Scrapers would be affected.  So, everyone with decent sites sat back and said, "Ah...this will be good...my rankings will increase." And then, the word started coming in that some really good sites took a massive hit.  We've got a lot of theories on what could be causing the hit, but there doesn't seem to be an obvious fix. Many of the key factors that have been suggested causes of a site to look bad in Panda's eyes are present on one of my sites, but this site actually increased in rankings after Panda. So, this is my theory:  I think that Google made some random changes that made no sense.  They made changes that would cause some scraper sites to go down but they also knew that many decent sites would decline as well. Why would they do this?  The result is fantastic in Google's eyes.  They have the whole world of web design doing all they can to create the BEST quality site possible.  People are removing duplicate content, reducing ad clutter and generally creating the best site possible.  And this, is the goal of Larry Page and Sergey Brin...to make it so that Google gives the user the BEST possible sites to match their query. I think that a month or so from now there will be a sudden shift in the algo again and many of those decent sites will have their good rankings back again.  The site owners will think it's because they put hard work into creating good quality, so they will be happy.  And Google will be happy because the web is a better place. What do you think?

Is it dangerous to have your H1 tag and your title the exact same thing?  My thought was that it's not be the best use of space, but that it couldn't cause harm. What do you think?
