Here’s the solution! Most online Google Sitemap generators only spider up to 500 pages. If you have a site with an active blog you are out of luck. Well until now. Click our blog post title to visit a site that I have just found today that allows you to make a Google Sitemap for up to 5,000 pages fairly easily.
Okay you have a few steps, but if you can not install Python on your web server, are not programatically literate, or like me, simply want to not have to reinvent the wheel, then this may be a good solution for you too.
You need to set up a free account at Free Site Map Generator, then install a special blank text file in the root just to verify your site and click start. The spider creates a site map for you and then allows you to download it as a .zip file.
Here’s where you need to manipulate it a bit, open the zip file and then create a .gz file. I use a free utility called win-gz which I found on the Web. Then upload your new sitemap.xml.gz file to your server and feed it to Google Webmaster Central. Why take the extra step to .gz it? Well if you have a big site, do Google a favor and make it easy to snatch the files. Google Sitemaps do understand the .gz format. In fact at the very beginning of Google Sitemaps this was the only format in which you loaded your sitemap. Now Google will take just plain .xml files, but they do stipulate that for big sitemaps it is best to provide the compressed .gz format.
I have tried a number of other sitemap generators and here is one that I really like for small sites http://www.xml-sitemaps.com/. This generator creates a .xml, .xml.gx, ror.xml, and urllist.txt file and is very easy and fast.
So now you have choices for making a Google Sitemap online whether your site is big or small.
