Sitemaps during a migration - which is the best way of dealing with them?
-
Many SEOs I know simply upload the new sitemap once the new site is launched - some keep the old site's URLs on the new sitemap (for a while) to facilitate the migration - others upload both the old and the new website together, to support the migration. Which is the best way to proceed? Thanks, Luke

Very much appreciated CleverPhD!

Found this while looking for a answer for another question could not find this the other day- right from the mouth of Google to not include pages that do not exist in XML sitemaps.
http://googlewebmastercentral.blogspot.com/2014/10/best-practices-for-xml-sitemaps-rssatom.html
URLs
URLs in XML sitemaps and RSS/Atom feeds should adhere to the following guidelines:
- Only include URLs that can be fetched by Googlebot. A common mistake is including URLs disallowed by robots.txt — which cannot be fetched by Googlebot, or including URLs of pages that don't exist.

Mate nailed it completely!

I would say make sure that your new sitemap has all the latest URLs. The reason people say that you should have old URLs in the sitemap is so that Google can quickly crawl the old URLs to find the 301s to the new URLs.
I am not convinced that this helps. Why?
Google already has all your old URLs in its systems. You would be shocked how far back Google has data on your site with old URLs. I have a site that is over 10 years old and I still see URL structures referenced in Google from 7 years ago that have a 301 in place. Why is this?
Google will assume that, "Well, I know that this URL is a 301 or 404, but I am going to crawl it every once in a while just to make sure the webmaster did not do this by mistake." You can notice this in Search Console error or link reports when you setup 301s or 404s, they may stay in there for months and even come back once they fall out of the error list. I had an occurrence where I had some old URLs showing up in the SERPs and various Search Console reports for a site for 2 years following proper 301 setups. Why was this happening?
This is a large site and we still had some old content still linking to the old URLs. The solution was to delete the links in that old content and setup a canonical to self on all the pages to help give a definitive directive to Google. Google then finally replaced the old URLs with the new URLs in the SERPs and in the Search Console reports. The point here being that previously our site was giving signals (links) that told Google that some of the old URLs were still valid and Google was giving us the benefit of the doubt.
If you want to have the new URLs seen by Google, show them in your sitemap. Google already has all the old URLs and will check them and find the 301s and fix everything. I would also recommend the canonical to self on the new pages. Don't give any signals to Google that your old URLs are still valid by linking to them in any way, especially your sitemap. I would even go so far as to reach out to any important sites that link to old URLs to ask for an updated link to your site.
As I mentioned above, I do not think there is an "advantage" of getting the new URLs indexed quicker by putting old URLs in the sitemap that 301 to the new URLs. Just watch your Google Search Console crawl stats. Once you do a major overhaul, you will see Google really crawl your site like crazy and they will update things pretty quick. Putting the old URLs in the sitemap is a conflicting signal in that process and has the potential to slow Google down IMHO.

Best way to "Prune" bad content from large sites?
I am in process of pruning my sites for low quality/thin content. The issue is that I have multiple sites with 40k + pages and need a more efficient way of finding the low quality content than looking at each page individually. Is there an ideal way to find the pages that are worth no indexing that will speed up the process but not potentially harm any valuable pages? Current plan of action is to pull data from analytics and if the url hasn't brought any traffic in the last 12 months then it is safe to assume it is a page that is not beneficial to the site. My concern is that some of these pages might have links pointing to them and I want to make sure we don't lose that link juice. But, assuming we just no index the pages we should still have the authority pass along...and in theory, the pages that haven't brought any traffic to the site in a year probably don't have much authority to begin with. Recommendations on best way to prune content on sites with hundreds of thousands of pages efficiently? Also, is there a benefit to no indexing the pages vs deleting them? What is the preferred method, and why?

Best Practices for Homepage Title Tag
Hi, I would like to know if there is any update about the best practices for the homepage title tag. I mean, a couple of years ago, it was still working placing main keywords in the homepage title tag. But since the last google SERP update, the number of characters that are being shown were reduced, and now we try to work with 55 and 56 characters. That has reduced our capacity of including many keywords on the title tag. Besides, search engines are smarter now to choose the correct inner page to show in SERP. But I am wondering if the Homepage Title should have a branded orientation or should include main keywords, cause it is still working that strategy. I would appreciatte any update in this issue. Thank you!

Is it worth creating an Image Sitemap?
We've just installed the server side script 'XML Sitemaps' on our eCommerce site. The script gives us the option of (easily) creating an image sitemap but I'm debating whether there is any reason for us to do so. We sell printer cartridges and so all the images will be pretty dry (brand name printer cartridge in front of a box being a favourite). I can't see any potential customers to search for an image as a route in to the site and Google appears to be picking up our images on it's own accord so wonder if we'll just be crawling the site and submitting this information for no real reason. From a quality perspective would Google give us any kind of kudos for providing an Image Sitemap? Would it potentially increase their crawl frequency or, indeed, reduce the load on our servers as they wouldn't have to crawl for all the images themselves?

Whats googles view on this, is this bad for seo?

Best way to noindex an image?
Hi all, A client wanted a few pages noindexed, which was no problem using the meta robots noindex tag. However they now want associated images removed, some of which still appear on pages that they still want indexed. I added the images to their robots.txt file a few weeks ago (probably over a month ago actually) but they're all still showing when you do an image search. What's the best way to noindex them for good, and how do I go about implementing it? Many thanks, Steve

What is the best way to optimize/setup a teaser "coming soon" page for a new product launch?
Within the context of a physical product launch what are some ideas around creating a /coming-soon page that "teases" the launch. Ideally I'd like to optimize a page around the product, but the client wants to try build consumer anticipation without giving too many details away. Any thoughts?

How to deal with old, indexed hashbang URLs?
I inherited a site that used to be in Flash and used hashbang URLs (i.e. www.example.com/#!page-name-here). We're now off of Flash and have a "normal" URL structure that looks something like this: www.example.com/page-name-here Here's the problem: Google still has thousands of the old hashbang (#!) URLs in its index. These URLs still work because the web server doesn't actually read anything that comes after the hash. So, when the web server sees this URL www.example.com/#!page-name-here, it basically renders this page www.example.com/# while keeping the full URL structure intact (www.example.com/#!page-name-here). Hopefully, that makes sense. So, in Google you'll see this URL indexed (www.example.com/#!page-name-here), but if you click it you essentially are taken to our homepage content (even though the URL isn't exactly the canonical homepage URL...which s/b www.example.com/). My big fear here is a duplicate content penalty for our homepage. Essentially, I'm afraid that Google is seeing thousands of versions of our homepage. Even though the hashbang URLs are different, the content (ie. title, meta descrip, page content) is exactly the same for all of them. Obviously, this is a typical SEO no-no. And, I've recently seen the homepage drop like a rock for a search of our brand name which has ranked #1 for months. Now, admittedly we've made a bunch of changes during this whole site migration, but this #! URL problem just bothers me. I think it could be a major cause of our homepage tanking for brand queries. So, why not just 301 redirect all of the #! URLs? Well, the server won't accept traditional 301s for the #! URLs because the # seems to screw everything up (server doesn't acknowledge what comes after the #). I "think" our only option here is to try and add some 301 redirects via Javascript. Yeah, I know that spiders have a love/hate (well, mostly hate) relationship w/ Javascript, but I think that's our only resort.....unless, someone here has a better way? If you've dealt with hashbang URLs before, I'd LOVE to hear your advice on how to deal w/ this issue. Best, -G
