I think you are right here, however the pages have links from sites we now probably don;t want from a link build perspective. I am concerned that these links (mainly low PR sites, forums etc) may do more harm than good so to funnel any link juice they have may be more damaging.

Any other suggestions here?

Based on my experience it's usually some incoming links/links that you have missed that causes this.

A 301-redirect to a working page should fix this permanently.

I need help on how best to do a complicated site migration. Replacing certain pages with all new content and tools, and keeping the same URL's. The rest just need to disappear safely. Somehow.

I'm completely rebranding a website but keeping the same domain. All content will be replaced and it will use a different theme and mostly new plugins. I've been building the new site as a different site in Dev mode on WPEngine. This means it currently has a made-up domain that needs to replace the current site. I know I need to somehow redirect the content from the old version of the site. But I'm never going to use that content again. (I could transfer it to be a Dev site for the current domain and automatically replace it with the click of a button - just as another option.) What's the best way to replace blahblah.com with a completely new blahblah.com if I'm not using any of the old content? There are only about 4 URL'st, such as blahblah.com/contact hat will remain the same - with all content replaced. There are about 100 URL's that will no longer be in use or have any part of them ever used again. Can this be done safely?

Duplicate Content Errors new website. How do you know which page to put the rel canonical tag on?

I am having problems with duplicate content. This is a new website and all the pages have the same page and domain rank, the following is an example of the homepage. How do you know which page to use the canonical tag on? http://medresourcesupply.com/index.php http://medresourcesupply.com/ Would this be the correct way to use this? Here is another example where Moz says these are duplicates. I can't figure out why because they have different url's and content. http://medresourcesupply.com/clutching_at_the_throat http://medresourcesupply.com/index.php?src=gendocs&ref=detailed_specfications &category=Main

Google Webmaster Tools -> Sitemap suddent "indexed" drop

Hello MOZ, We had an massive SEO drop in June due to unknown reasons and we have been trying to recover since then. I've just noticed this yesterday and I'm worried. See: http://imgur.com/xv2QgCQ Could anyone help by explaining what would cause this sudden drop and what does this drop translates to exactly? What is strange is that our index status is still strong at 310 pages, no drop there: http://imgur.com/a1sRAKo And when I do search on google site:globecar.com everything seems normal see: http://imgur.com/O7vPkqu Thanks,

Do Google webmaster tool and other backlinks analysis tool ignore the disavow data ?

Hello, Lots of site i have disavow so if i download backlinks of my site from google webmaster so google will ignore the disavow data and give me backlinks other than disavow data? Same if i use backlink tools like moz or semrush or ahref etc for checking backlinks of my site or competitor site so will this tool ignore the disavow data? If such tools not aware of disavow then it is worthless to check competitor links? Thanks! dev

How should I go about repairing 400,000 404 error pages?

My thinking is to make a list of most linked to and most trafficked error pages, and just redirect those, but I don't know how to get all that data because i can't even download all the error pages from Webmaster Tools, and even then, how would i get backlink data except by checking each link manually? Are there any detailed step-by-step instructions on this that I missed in my Googling? Thanks for reading!!

Does Google make continued attempts to crawl an old page one it has followed a 301 to the new page?

I am curious about this for a couple of reasons. We have all dealt with a site who switched platforms and didn't plan properly and now have 1,000's of crawl errors. Many of the developers I have talked to have stated very clearly that the HTacccess file should not be used for 1,000's of singe redirects. I figured If I only needed them in their temporarily it wouldn't be an issue. I am curious if once Google follows a 301 from an old page to a new page, will they stop crawling the old page?

Amount of pages indexed for classified (number of pages for the same query)

I've notice that classified usually has a lots of pages indexed and that's because for each query/kw they index the first 100 results pages, normally they have 10 results per page. As an example imagine the site www.classified.com, for the query/kw "house for rent new york" there is the page www.classified.com/houses/house-for-rent-new-york and the "index" is set for the first 100 SERP pages, so www.classified.com/houses/house-for-rent-new-york www.classified.com/houses/house-for-rent-new-york-1 www.classified.com/houses/house-for-rent-new-york-2 ...and so on. Wouldn't it better to index only the 1st result page? I mean in the first 100 pages lots of ads are very similar so why should Google be happy by indexing lots of similar pages? Could Google penalyze this behaviour? What's your suggestions? Many tahnks in advance for your help.

Does having multiple links to the same page influence the Link juice this page is able to pass

Say you have a page and it has 4 outgoing links to the same internal page. In the original Pagerank algo if these links were links to an page outside your own domain, this would mean that the linkjuice this page is able to pass would be devided by 4. The thing is i'm not sure if this is also the case when the outgoing link, is linking to a page on your own domain. I would say that outgoing links (whatever the destination) will use some of your link juice, so it would be better to have 1 outgoing link instead of 4 to the same destination, the the destination will profit more form that link. What are you're thoughts?
