Hi John,

As long as you've implemented rel=prev and rel=next markup on your paginated content, having duplicate title tags on these pages shouldn't be a problem at all. If you're really concerned about it, you could update the title tags on subsequent pages to say e.g. "Page 2" at the end, but if you've already marked it up as paginated content it should be fine. Hope that helps!

Do the reviews appear anywhere else on the web? Are people leaving reviews on the reviewer's site, and they're visible there, and then you're pulling them in via this widget? Or are they only visible on your site, through the widget?

If the reviews are elsewhere on the web (for example on a review site such as Yelp or Angie's List), Google is going to understand that that content belongs on that site. Pulling it in via this widget probably won't send much in the way of a unique content signal; it's unlikely that it would be seen as duplicate content, though, as long as the page it appears on also has its own unique content. Appearing through the widget also means you likely won't be able to mark up the reviews using schema.org.

If they appear somewhere else, and Google can easily associate those reviews with your product, you'd probably be better served having a function on your own website where people can review your products there. Then, let those reviews live on your site, and the third-party reviews stay on the third-party reviewer site.

There are a few different things this could be, none of which are that much cause for concern, thankfully.

Some questions to ask:

• Where are you seeing the rankings fluctuate? In the Google interface? In a ranking tool? In multiple tools? Since Google is testing things all the time and results are more and more personalized, it's pretty common to see keyword fluctuations, especially in rank tracking tools. I would check the keyword in a second ranking tool, and also Google it in a private window, to see if you can duplicate the results - if not, it may be a quirk of the tool and not of the rankings.
• Along those same lines - do you see your organic traffic to that page fluctuate along with the fluctuations in ranking? Since you're on page 2, you may not be getting a ton of traffic from that specific term, but it's worth checking on.
• If that's not the case and the rankings really are fluctuating, what other changes can you note in the SERPs during the changes? One example from my own life: I had a client who was targeting a term that Google seemed to be trying to figure out whether or not it was appropriate to show local/localized results. The presence or absence of that local pack changed that SERP a lot.

Ranking fluctuations like this are pretty common, especially once you drop off the first page. If it's not seriously impacting your traffic or conversions, I wouldn't be too concerned about it. Your best defense here is a good offense - try to bolster that page's rankings and authority to get it on page 1. I know that's easier said than done, but it's a lot easier to deal with ranking fluctuations when they're between spot 4 and spot 7, instead of page 2 and page 5.

This is fine, as long as you don't want to exclude robots from crawling any part of your site.

I agree that it's probably not a huge problem, but still something to clean up if you can - it would be best if crawlers weren't trying to access these pages.

If Moz and Webmaster Tools are showing the 403 error, it means that they are able to crawl to the URLs that are returning the 403 - so somewhere on your site or on the web, pages that are accessible by bots and crawlers are linking to these pages that don't exist yet. Having a bunch of errors on your site can impact Google's ability to crawl it well, which can impact your rankings, so it's best to get those cleaned up. In Webmaster Tools you should be able to click on the pages and see which pages are linking to them, so you can remove those links; you can do the same using a tool like Screaming Frog if you'd prefer. Good luck!

Hi Dan,

It's important to remember that Domain Authority is a Moz-specific metric, measuring the power that inbound links to a domain are passing to it. It's based on a lot of research and information about how Google measures links, but isn't necessarily a reflection of how Google is actually perceiving and rating the inbound links to your site (since no outside party knows for sure exactly how Google is measuring link signals at any given time). Since those links still point to the legacy domains, they are still coming up in the Moz tools as having high DA. It's probable that Google is interpreting those signals passing through your redirects correctly and passing that link value on to your main domain, but if those redirects go away, that may change.

URLs will often remain in the index when they have links pointing to them, because Google is indexing the presence of that link - but a URL showing up in a site: search doesn't necessarily mean that it's ever showing up for any query. Is your main domain still getting a lot/much/any traffic from your legacy domains through those redirects? How much traffic is still getting to those legacy domains (whether via organic search traffic to still-indexed pages or, more likely, from people clicking on inbound links to the old pages) will dictate whether or not you need to keep the redirects live.

One thing I would recommend doing, that I always recommend when a domain is moved, is reaching out to the sites that link to your old domain and seeing if you can get them to update the links to the new domain. You won't have anywhere close to a 100% success rate with this, but it can decrease the number of links that are passing value through redirects and increase the number that pass value directly.

If you do decide to decommission the server and not re-host the redirects elsewhere, I would recommend planning that move in conjunction with a link building and promotion campaign for the new site, to attract new links to make up for any link juice that is lost from the old domains' redirects. I hope that helps!
