Is submitting site map advisable after 1.5 yrs

[Modi]

Hello,

is submitting site map advisable after 1.5 yrs - especially when we are finding mostly all of pages getting indexed

we have basically 2 questions

• is submitting site map good for seo and crawling

- Does it not hinder the crawler to index the submitted pages only - as we get on close to 250 - 300 new pages monthly on site added on every month

Basis above - seek expert opinion to

- submit site map to google or not ?

• If yes - in how much time do we need to update site map

• which are good site map generator sites

Depending on your sites hierarchy and structure, the sitemap may make the whole crawling process easier for Google rather than making the crawler dig through your menus and links to find pages within your site.  So in that case, it wont limit Google.

Sitemaps can also include instructions on how often a page changes to determine how often Google should revisit that page.  If your pages that have already been crawled are fairly static and do not change often, set the crawl frequency rate to low so you dont have to worry about taking up too much of your crawling bandwidth on already indexed pages.

Here is a good blog post about setting your sitemap page priority levels:

Hi May,

Thanx

just a query - when a site map is submitted , and later on when new pages n urls are been added - will it not limit google to crawl only the pages as per site map and not additional pages.

Hi

I would say yes, I am of the belief that a sitemap is never a bad idea and submitting one (even later on) won't hurt anything.  It also sounds like you have a rather large site, so this will help get those new pages added each month crawled.   Even if all of your URLs are indexed, you can still use sitemaps to provide Google with information about other content such as videos and mobile versions of your site (if any).  It should actually help the crawler rather than hinder it.

As far as generator sites, I don't have a particular one to recommend but doing a google search for "sitemap generator" pulls up a lot of results.  You may want to test some of those and see what works best for your needs as many of them limit the number of pages crawled.

If you are using a CMS like Wordpress or Joomla there are sitemap plugins to help with this process.
