        Mostly no on iFrames, or not in a reliable way. Redirect 303 is more uncommon, but similar to a 302. Either one is not the way to permanently send old content to new. Google has a guide on redirection here: https://support.google.com/webmasters/answer/93633, and iFrames here: https://support.google.com/webmasters/answer/34445.  Cheers!

          If I disavow bad links on "disavow link webmaster" will they still show up on my moz reports?

          We recently found out we have a lot of bad links linking back to our website from spam sites, I disavowed them through the google disavow link webmaster. On my moz report it still shows the links, is that normal?

          Redirects affect on page and domain authority

          Hi - excuse me if this is stupid question but I'm rather new to this. Currently the PA for the home page is 16 and the DA 28 and I have some concerns that my efforts are being diluted. When I use OSE on www.sassandgrace.co.uk I get different link results to sassandgrace.co.uk but there is a redirect in place to sassandgrace.co.uk and cannot run a crawl report, for example, on www.sassandgrace.co.uk. The PA and DA are identical for each but the number of links different With a smallish number of links pointing to each but with a redirect in place, am I losing some of the effect or is having the redirect in place giving me all the credit for links to both addresses? Thanks

          Asking a site to remove a "nofollow" on a link to our client

          Hello, We created a good infographic for a client of ours and a large tech site (DA 86) picked up and ran a story on it. We didn't contact this company asking them to feature it, they have just picked it up through other shares around the Web. I understand that, at the end of the day, it's their prerogative whether to "nofollow" their links or not, but surely they should be giving our client some credit as they have clearly deemed the graphic newsworthy and felt that it would appeal to their readership. I've emailed said tech site, but to no avail. Does anyone have any advice on this? Or is it just a case of they can do what the heck they want? I know that our client will still benefit from the additional referral traffic, but a follow link would have been nicer! Cheers, Lewis

          Adding backlinks in old articles?

          I am trying to get a few more links to get a few of my pages to rank and I am thinking about adding some more backlinks on my own site on some of the old blog articles as well as some of my other related blogs. My question is - is it still beneficial to link from these articles that are say 1 year old or more, or would it be far more valuable to write new articles on the blog containing those same links?

          A link with "return false"- OSE sees as a No Followed Link

          Hello, I couldn't find a clear answer to the impact on SEO for a link written in this way: [" class="expert_info" onclick="window.open(this.href);return false;">](w</span>ww.yourwebsite.com<span style=) [Does the "return false" act as a "no follow"? I came across this in our link data in Open Site Explorer which lists these links all as "no follows." However, an engineer I spoke to said that it shouldn't impact search engine behavior. Any ideas? Thank you in advance! -Sarah K.](w</span>ww.yourwebsite.com<span style=)

          How to remove backlinks?

          Hey guys, With all this anti over optimization movement going around with Google, I decided to do a link building profile audit. I see some pages with PR 0 and some pages that expired. My websites are not penalized at this moment, however I do want to avoid this at all costs. What can I do? Could a backlink from an expired domain penalize my site?

          Building backlinks for a newspaper site?

          Anyone have tips on building links to a newspaper site? I am looking for a strategy to create links to a news site beyond building one link at a time. We have so much content that is constantly updated that it would be impossible to do this one page at a time.

          Frustrated with spammy backlinks from competitors

          I've only been doing SEO for my company for the last month and I've made some headway but what is really frustrating me right now is a couple of competitors that have OBVIOUS spammy links ranking in the number 1,2,3 stops all over the board for the keywords i'm going for.  One competitor in particular has anchor text links EVERYWHERE that make absolutely no sense...junk like... "I have never been more saddened by anything in my life than when my grandfather got cancer.  I told my uncle he needed to buy some auto insurance.  I really like pork." I mean, these links are the pages with the most page authority and page rank out of all of the ones they have...and I'd venture to say that almost all of their backlinks are like this...well, half of them are just random links with good anchor text on the sidebar of a bazillion spam websites (diapers, toys, fake blogs, etc.)...while i have about 3k links and most of my top competitors have about 5k links...these guys have over 33k. Worse yet, when I look at something like Alexa rank, they have pretty high overall traffic rank but it shows traffic rank in MX (mexico) instead of the US...these guys only sell in the US!  I mean, they're black hat if I've ever seen such a thing and they rank superbly on all keywords. What can I do to compete with this junk?
