How important are sitemap errors?
-
If there aren't any crawling / indexing issues with your site, how important do thing sitemap errors are? Do you work to always fix all errors?
I know here: http://www.seomoz.org/blog/bings-duane-forrester-on-webmaster-tools-metrics-and-sitemap-quality-thresholds
Duane Forrester mentions that sites with many 302's 301's will be punished--does any one know Googe's take on this?
-
Very important. Particularly if you have a large site. We operate a large site with 100,000's of pages and as Dan said it can be difficult to maintain. We use something called Unlimited XML Sitemap Generator which builds XML sitemaps for us automatically. I'd highly recommend it although it takes a bit of fiddling with to get it up and running as it's software which sits on site. We couldn't manage without it as we'd be forever on sitemaps.
We found that getting sitemaps right on a large site made a huge difference to the crawl rate that we encountered in GWT and a huge indexation to follow.
In particular check for 302's. I made the mistake of leaving those for a while and am sure that we suffered from some loss of link equity along the way.
Hope it helps

Your sitemap should only list pages that actually exist.
If you delete some pages, then you need to rebuild the sitemap.
Ditto if you delete them and redirect.
Google is always lagging, so if you delete 10 pages and then update the sitemap, even if google downloads the sitemap immediately, they will still be running crawls on the old map, and they may be crawling the now-missing pages, but haven't shown the failures in your WMT yet.
If you update your sitemap quickly, it is possible they will never crawl the missing pages and get a 404 or 301.
(but of course, there could be other sites pointing to the now-missing pages, and the 404s will show up elsewhere as missing)
I am always checking, adding, deleting and redirecting pages, and I update the current sitemap every hour and all the others are rebuilt at midnight every night. I usually do deletions just before midnight if I can, to minimize the time the sitemap is out of sync.

As far as I know Google is more lenient with sitemap errors, but I would still recommend looking into it. The first step would be to be sure your sitemap is up to date to begin with - and has all the URLs you want (and not any you don't want). The main thing is none of them should 404 and then beyond that, yes, they should return 200's.
Unless you're dealing with a gigantic site which might be hard to maintain, in theory there shouldn't be errors in sitemaps if you have the correct URLs in there.
Even better, if you're running WordPress the Yoast SEO plugin will generate an XML sitemap for you and it update automatically.
Hope that helps!

Spotify XML Sitemap
All, Working on an SEO work up for a Spotify site. Looks like they are using a sitemap that links to additional pages. A problem, none of the links are actually linked within the sitemap. This feels like a strong error. https://lubricitylabs.com/sitemap.xml Thoughts?

Do I have to many internal links which is diluting link juice to less important pages
Hello Mozzers, I was looking at my homepage and subsequent category landing pages on my on my eCommerce site and wondered whether I have to many internal links which could in effect be diluting link juice to much of the pages I need it to flow. My homepage has 266 links of which 114 (43%) are duplicate links which seems a bit to much to me. One of my major competitors who is a national company has just launched a new site design and they are only showing popular categories on their home page although all categories are accessible from the menu navigation. They only have 123 links on their home page. I am wondering whether If I was to not show every category on my homepage as some of them we don't really have any sales from and only concerntrate on popular ones there like my competitors , then the link juice flowing downwards in the site would be concerntated as I would have less links for them to flow ?... Is that basically how it works ? Is there any negatives with regards to duplicate links on either home or category landing page. We are showing both the categories as visual boxes to select and they are also as selectable links on the left of a page ? Just wondered how duplicate links would be treated? Any thoughts greatly appreciated thanks Pete

Where is the best place to put a sitemap for a site with local content?
I have a simple site that has cities as subdirectories (so URL is root/cityname). All of my content is localized for the city. My "root" page simply links to other cities. I very specifically want to rank for "topic" pages for each city and I'm trying to figure out where to put the sitemap so Google crawls everything most efficiently. I'm debating the following options, which one is better? Put the sitemap on the footer of "root" and link to all popular pages across cities. The advantage here is obviously that the links are one less click away from root. Put the sitemap on the footer of "city root" (e.g. root/cityname) and include all topics for that city. This is how Yelp does it. The advantage here is that the content is "localized" but the disadvantage is it's further away from the root. Put the sitemap on the footer of "city root" and include all topics across all cities. That way wherever Google comes into the site they'll be close to all topics I want to rank for. Thoughts? Thanks!

Should sitemap include https pages?
Hi guys, Trying to figure out some onsite issues I've been having. Would appreciate any feedback on the following 2 questions: My homepage (http://mysite.com) is a 301 redirect to https://mysite.com, which is under SSL. Only 2 pages of my site are https, the rest are http. Should the directory of my sitemap be https://mysite.com/sitemap.xml or should it be kept with http (even though the redirected homepage is to https)? Should my sitemap include the https pages (only 2 pages) as well as the http? Thanks, G

Recovering from robots.txt error
Hello, A client of mine is going through a bit of a crisis. A developer (at their end) added Disallow: / to the robots.txt file. Luckily the SEOMoz crawl ran a couple of days after this happened and alerted me to the error. The robots.txt file was quickly updated but the client has found the vast majority of their rankings have gone. It took a further 5 days for GWMT to file that the robots.txt file had been updated and since then we have "Fetched as Google" and "Submitted URL and linked pages" in GWMT. In GWMT it is still showing that that vast majority of pages are blocked in the "Blocked URLs" section, although the robots.txt file below it is now ok. I guess what I want to ask is: What else is there that we can do to recover these rankings quickly? What time scales can we expect for recovery? More importantly has anyone had any experience with this sort of situation and is full recovery normal? Thanks in advance!

Is DOCTYPE important for SEO?
Hello fellow Mozzers. I am just having a brief look at a potential clients website before speaking to them tomorrow and whilst looking at the source I noticed that they don't appear to have a clear definition for their Doctype. All the have at the top of each page is I have to admit that Doctypes aren't my strong point but I know that they are normally slightly more descriptive than this. Can this have any effect on rankings? or is this just an issue for W3C validation? Thanks 🙂

Sitemaps. When compressed do you use the .gz file format or the (untidy looking, IMHO) .xml.gz format?
When submitting compressed sitemaps to Google I normally use the a file named sitemap.gz A customer is banging on that his web guy says that sitemap.xml.gz is a better format. Google spiders sitemap.gz just fine and in Webmaster Tools everything looks OK... Interested to know other SEOmoz Pro's preferences here and also to check I haven't made an error that is going to bite me in the ass soon! Over to you.
