As most of you have heard by now, last month Google launched a new
service called Google Sitemaps. As described on Google: "It's
a collaborative crawling system that enables you to communicate
directly with Google to keep us informed of all your web pages,
and when you make changes to these pages."
Hmmm, doesn't this remind you of a service we introduced in this newsletter back in March, called ROR?
Anyway, here is a great article about Google Sitemaps. We thought you might find it useful.

Three Ways to Index your Site with Google Sitemaps:
Difficult, Hard, and Easy
Posted on July 6, 2005
By Titus Hoskins
Google has recently implemented a program where any webmaster
can create a Sitemap of their Site and submit it for indexing
by Google. It is a quick and easy way for you to keep your
site constantly indexed and updated in Google. The program is appropriately called Google Sitemaps.
In order for you to best use Sitemaps, you must have an XML generated
file on your site that will transmit or send any updates, changes, and
data to Google. XML (Extensible Markup Language)is everywhere these days,
you have probably seen the orange Xml logo on many web sites and its
often associated with Blogging because Blogs use XML/RSS feeds to
syndicate their content.
Today RSS is known mostly as 'Really Simple Syndication' but its original
acronym stood for 'Rich Site Summary'. XML
is only simple code like HTML and it is used to syndicate your
content to all interested parties.
And the interested party in this case is Google. By creating
Sitemaps Google is really asking webmasters to take charge of
the indexing and updating of their sites. Basically, doing
the Googlebot's job!
This is a 'Good' thing! With the steady influx of new web sites
growing rapidly, indexing all this material will become a challenge,
even with the resources of Google. With Sitemaps, websmasters can
now take charge and make sure their site crawled and indexed.
Please note, indexing your site with Sitemaps WON'T improve
your rankings in Google. You will still be competing with the other
sites in Google for top positions. But with Sitemaps you can make
sure all your pages are crawled and indexed quickly by Google.
There are some other big advantages of using Google's Sitemaps
- mainly you have control over a few key variables, attributes or tags.
To explain this as simply as possible, your XML powered sitemap
file will have this simple code for each page of your site:
Along with 'urlset' tags at the beginning and end of your code,
and an XML version indication - that's basically your XML file!
File size will depend on the number of webpages you have.
Taking a closer look at this XML file:
location - http://www.yoursite.com - name of your webpage
priority - you set the priority you want Google to place on that page
in your site. You can prioritize your pages: 0.0 being the least,
1.0 being the highest, 0.5 is in the middle. This is ONLY relative to
your site. It will not affect your rankings. Why is this important?
You have certain pages on your site that are more important than
others, (home page, high profit page, opt-in page, etc.) by placing high
priority on these pages, you will increase their importance in Google.
last modified - when you last modified that page, this timestamp allows
crawlers to avoid recrawling pages that haven't changed.
change frequency - you can tell Google how often you change that
particular page. Never, weekly, daily, hourly, and so on - if you
frequently update your page this could be extremely important.
Why do I need a XML Generator?
In order for this XML sitemap file on your site to be constantly
updated, you need a Generator that will spider your site, list
all the urls and automatically feed them to Google. Thus constantly
updating your site in Google's massive index or database.
Keep in mind, Google also gives you the option of submitting
a simple text file with all your URLs.
Now there is already a flood of these generators popping up! Different
ways of generating your XML powered sitemap file. More are probably appearing
as you read this. But lets look at Three ways to generate your XML file.
Difficult - Google's Python Generator
That's a relative term, if you know your server like the back of your
hand and installing scripts doesn't scare the bejesus out of you,
you're probably smiling at the word difficult. Google supplies a link to a
generator which you can download and set up on your server. It will cough
up your sitemap XML file and automatically feed it to Google. Google XML Generator
In order for this Generator to work, Python version 2.2 must be installed
on your web server - many servers don't have this. If you know what you're
doing, this will probably be a good choice.
You don't need a Google Account to use Sitemaps but it's encouraged
because you can track your sitemap's progress and view diagnostic
information. If you already have another Google Account gmail,
Google Alerts, etc. just use that one to sign in and follow directions
To submit your Sitemap using an HTTP request, issue your request
to the following URL:
Hard - A PHP Code Generator
This is a php generator that you can place on your server. This
generator will spider your site, and produce XML sitemap file. Download
the phpSitemapNG and upload it your server. Run the generator to get
your XML sitemap file and send it to Google. PHP Generator
Again, this is only hard to do if you don't know your way around PHP
files or scripts.
Easy - Free Online Generator
These Generators are popping up everywhere, and Google now keeps a list of
these 'third party suppliers' of generators on their site. Find them here: Google's List of Third Party Generators
One of the easiest to use is www.xm-sitemaps.com, and you can
index up to 500 pages with this online Generator very quickly and it will
give you the sitemap XML file Google needs to index your site.
It will go into your site, spider it and index all your pages into an
XML sitemap of your site. You can download this file, Compressed or Non-
compressed and make minor changes such as setting the priority,
changing frequency, etc.
Then upload this file to your site as sitemap.xml to the root directory
of your server i.e. where you have your homepage. Then notify Google
Sitemaps of your XML file and you're in business.
Of course, the only drawback, if you constantly add pages to your site
you will need to also add these pages to your XML sitemap file.
This won't be much of a problem unless you're daily adding pages
to your site - then you will need something like the PHP or Python
generator to do all this for you automatically.
Google is still the major search engine on the web so getting your
pages indexed and updated quickly is the major reason to use Google
Sitemaps. If you want your site to remain competitive it's probably
the wisest route to take.
