Hi Bruce,
I have to make custom sitemap for one site & for that I would like to know something about blog module. If any new comment is added in any existing blog or if any new blog is created then how we can tell the search engine that our sitemap is modified?
I am explaing you below one my doubt with example so that you can have better idea about it.
There is one module in my site where item listing is displayed. User can add/edit item in it. Also there is one separate page to view the detail of that item. While viewing the item detail, page is having item name as its url. e.g. http://mysite/MyNewItem-detail.aspx. I have to create sitemap which contains details of the items (its friendlyurl, lastmodDate & priority). So whenever any new item is added then I want that my sitemap should be updated.
Is it possible to intentionally update the sitemap whenever any new item is added through coding? After reading some stuff related to sitemap, I think that addition of new items will be get effected when next time the searchenging will process my sitemap file. I have explaind it as below.
I think at some regular interval of time, when google or yahoo or anyother searchengine in which I have added the sitemap, will try to process that sitemap file and whatever the xml output it will get that latest urlset will be indexed in its search. E.g. I have added http://mysite/Mysitemap.axd as the sitemap in google. Currently there are only 5 items, so when first time it tries to process http://mysite/Mysitemap.axd file then dynamically urlset of these 5 items are generated and will be indexed by the searchengine. After some time say 5 hour or 1 day, 2 new items are added. So when next time after some regular interval when again google tries to process my sitemap file (http://mysite/Mysitemap.axd), then it will dynamically get the urlset of 7 items. So I assume that this way addition of new items or updates of existing item will be get effected in the search engine.
Please let me know whether my understanding regarding the sitemap processing is going in right direction or not? Or any good links which can help me to move ahead in right direction for the sitemap implementation.
Awating your reply,
