How To Build A Google Sitemap
Google has implemented a cutting edge method of crawling web
site for its search engine index. This unprecedented method of
indexing web pages is known as Google Sitemaps, and it is
quickly growing in popularity among webmasters and SEO agents
and managers due to its ability to get entire web site indexed
quickly and to pick up errors in the links coming into and out
of these web site.
Google Sitemaps consists of placing the URLs of your pages along
with important information regarding how Google should index
them into an XML document. This information is then read by the
Google Spider and the pages are normally indexed quite quickly
assuming that they are coherent to Google's standards for
indexing pages (and also assuming that the sitemaps conform to
Googles Sitemap Criteria which will be explained a little later).
There are two primary types of Google Sitemaps. The first is a
list of pages in a website and the second is a list of sitemaps
in the website. Google has limited the number of URLs in its
sitemaps to fifty thousand URLs. This may sound like a lot, but
for some of the more intricate web site, fifty thousand URLs may
not even make a dent in what they want indexed.
This led to the advent of the Google Sitemap index file which
can index up to one thousand sitemaps. If you do the math, this
means that you could have one thousand sitemaps with up to fifty
thousand URLs in each sitemap which allows for fifty million
URLs to be placed in your Google Sitemap scheme. But wait,
there's more. Who ever said that you can't have an index of
indexes? You could actually make an index of a thousand index
files which are all indexes of a thousand index files.
Basically, there is no limit to the number of URLs that you can
hold in your Google sitemaps.
Now that you understand the power of the Google Sitemap you're
probably asking yourself how to create and implement a Google
Sitemap. The first step is to simply create your sitemaps. Here
are the templates which are also available at http://www.google
.com/webmasters/sitemaps/
For a sitemap file use the following format:
http://www.example.com/
2005-01-01 monthly 0.8
http://www.example.com/catalog?item=12&desc=vacation_hawaii
weekly
http://www.example.com/catalog?item=73&desc=vacation_new_zea

Those of you not familiar with the latest on SEO now have at
least a basic understanding. But there's more to come.

Everything here is pretty self-explanatory with the exception of
the changefreq and the priority aspects. The changefreq asks how
often you think the page will change on average. The possible
values for the changefreq option are: always, hourly, daily,
weekly, monthly, yearly, and never. The priority aspect
basically just asks how important the particular page is in your
website. The value can be anywhere between 0.0 and 1.0. If you
decide not to specify a priority it will default to 0.5.
To create a sitemap index file follow the following format:
http://www.example.co
m/sitemap1.xml.gz 2004-10-01T18:23:17+00:00
http://www.example.co
m/sitemap2.xml.gz 2005-01-01
This is all pretty straight forward but it leads me to my next
point. You notice that the file names all end in .gz. Google
allows you to compress your sitemaps so that they take up less
of your disk space when you place them on your site and less of
your band width when Google downloads them (which it seems to do
approximately once every 9 hours or so). You may only use .gz
compression. If you try .zip, it won't work.
Now all that you really have to do is submit your sitemap to
google. In order to do this you must go to https://www
.google.com/webmasters/sitemaps/login and log into your
Google account. If you don't have a Google account, you can
create one. Once you log in you will be allowed to submit your
sitemap into the google index. At some point within about 24
hours of your submission, Google will give you the option to
place a small HTML file onto your website so that it can confirm
that you do, indeed, have access to editing the site. Once you
have done this it will begin to provide you with statistics
regarding your google sitemap. (Note that even without this
feature you can see when google downloaded the sitemap last and
what the status of the sitemap was at that time.)
How Google Sitemaps Fits Into Search Engine Optimization.
According to Google, the Sitemaps utility is free and will
continue to be - yet it's almost as good as the paid inclusion
service offered by rival search engines. So how can you take
advantage of this great service?
First of all, you should create a Google Account. Although you
can still use Google Sitemaps without an account, you need one
before you can use Google's tools to check your site
submissions. Once you do that and go to http://sitemaps.google.com,
you'll be guided through the process.
Google Sitemaps has a very helpful question and answer page that
will give you the help you need - the answers to most questions
people have can be found right there. Good luck!
Now that wasn't hard at all, was it? And you've earned a wealth
of knowledge, just from taking some time to study an expert's
word on SEO.
