Question about construction of our sitemap URL in robots.txt file

[Prospector-Plastics]

Another tool to help generate a sitemap and even check broken links is called Xenu (weird logo, but good free product).

[ChristopherGlaeser]

There is a limit on the size of a sitemap and to allow for large sitemaps to be split into smaller sitemaps, the sitemap protocol includes a sitemapindex.  See "Using Sitemap index files (to group multiple sitemap files)" here http://www.sitemaps.org/protocol.html.  Of course, it's also possible to include the multiple sitemaps in the robot.txt file, but automated sitemap generators will likely use the sitemapindex feature so that the robots.txt file does not have to be modified as the size of the site changes.

Best,
Christopher

Thanks Jarno,

I have downloaded and am trying the 30-day free trial of the A1 Sitemap Generator right now. Thanks for the tip. Can you comment on Christopher's remark below concerning sitemap indexes for larger sitemaps?

Can either you or Christopher give me more clarification on that. Is this what our IT director has attempted to do with the sitemap in our robots.txt file? If so, has it been done correctly?

Thanks!

Thanks Christopher,

Your answer took a noment to sink in, but I think I get it (I think I am coffee deprived this morning).

So, if I am using the A1 Sitemap generator that Jarno suggested, this sitemap index should automatically be generated based on the size of my generated sitemap. Is that correct?

[ChristopherGlaeser]

I'm not familiar with the A1 Sitemap generator, but regarding the sitemap protocol, there is a limit on the size of a single sitemap.xml file, so for large sites, the sitemap must be split into multiple sitemap.xml files.  And, the protocol has a method for indexing these multiple sitemap.xml files.  It's sort of like an index to an index.  None of my sites exceed the sitemap file limit, so I don't know which sitemap generators use this approach, but I would guess many of them do.

Sitemap generators I have used include DMXZone which is a Dreamweaver plugin, and xml-sitemaps.com which includes a video sitemap generator.

Best,
Christopher

EDIT: PS: Your current sitemap looks fine to me.

Hi again Jarno,

Is it normal for A1's sitemap generator's "Scan website"  function for images to take over two hours? Our site is about 3,500 URLs. So far it has under "Internal 'sitemap' URLs"  Listed found: 82076 (and climbing every few seconds).

I am wondering if there isn't something wrong? (I don't have any frame of reference since I've never used it before). Thanks!

A1 Sitemap does 2 things:

1 ) It builds a file names sitemap.xml which contains all files on the website (not conform the google requirements

2. It builds a number of files listed in sitemap-index.xml for every 100 pages in one sitemap. So if you're website contains 2800 pages You'll get loads of files: 28 sitemap-1.xml etc and 1 sitemap-index.xml file. Which does meet the Google standards. Afterwards you can do 2 things in Google webmasters:

3. enter the sitemap-index.xml file as a sitemap -> Google will follow everything and come to the grand total of 2800 pages.

4. Enter each sitemap separately.-> same result but you can pinpoint better where you have a 100 pages and google only indexes fewer (can happen).

Hope this helps

Dana,

sometimes that happens. Are you scanning for images or are you scanning the site?

i will check your site tomorrow with my full version and see what it does.

Sometimes with some websites you'll get things like this but it can be loads of things. 3500 pages should not take 2 hours but only a couple of minutes. I'll check it first thing tomorrow. A1 is not installed on my laptop..

Let you know tomorrow.

Kind regards

Jarno

Thanks Jarno. I really appreciate that. Yes, I had it selected to just scan for images (as prompted when I attempted to create an image sitemap). Let me know what you see? I am wondering if it is going around in circles?

Dana

[JarnoNijzing]

i started the scan and it's still busy:

2500 analyzed references so far.

Let you know how it turns out.

Jarno

[JarnoNijzing]

Dana,

It just finished scanning here are the results:

Internal Sitemap URL's:

• Listed found: 5248
• Listed deduced: 5301
• Analyzed content: 3110
• Analyzed references: 3176

External URL's:

• Listed found: 700

When i look at the overview of the result i see a number of 301 redirects, canonical redirects (when tested again the get code 200 OK). But I see a lot op pages.

When i build the sitemap it generates one file (no idea why not more then one) with all the links in the document. Google's sitemap protocol states it should be like the schema at sitemaps.org which it does. The entire protocol of sitemap.org states that a sitemap can not hold over 50,000 links and should be smaller then 10 MB in filesize.

The one I just build for you is only 1 MB and contains less url's then 50,000 and thus is it allowed by Google.

http://www.sitemaps.org/protocol.html

I can send you the entire version of the sitemap if you'd like in a personal message or through e-mail?

Hope this helps you further.

kind regards

Jarno

Hi Christopher,

Thanks for the update. Yes, I looked at it too and other than it not being "pretty" XML, the data seemed to be okay. The one thing the A! generator did that we couldn't do was assign the values for importance and frequency specific pages are modified. If that data is accurate, that's pretty cool. I'm just not sure, although it seems it did identify pages that are modified more frequently correctly. I have 30 days to play with the free trial, but so far I think I like it a lot.

Dana

[danatanseo]

Yes, we definitely use XENU, but I think I like Screaming Frog a bit better (although our IT Director swears it's broken).

[danatanseo]

Hi Jarno,

Thanks so very much! I have to say I am really liking the A1 generator. How awesome of you to follow up. I really appreciate that. Yes, if you want to send me the complete sitemap via PM that would be awesome. I certainly hope I can return the favor Happy Holidays!
