A subject that has been reported as causing a lot of concern is the subject of submitting a site map to Google, the concern comes from two different aspects.
The first is that people become daunted by the prospect of meeting the Protocol 0.9 standards and have trouble figuring out what is required. The link above will give you access to a complete set of code that has been generated, submitted to and approved by Google. Once viewed you will see that for relatively straight forward websites the code really isn’t very complicated.
The second aspect is that for some reason you may be penalised for submitting a site map. In Google’s own words ‘no one will ever be penalised for submitting a site map’. On the other hand there are no promises that there will be an automatic indexing of sites that are submitted or any guaranteed improvement in page ranking. In other words there is noting to lose and potentially everything to be gained but with no promises.
If you use Googles webmaster tools you can submit an RSS feed as a site map for your blogs which is one of the easiest ways of submission. Alternatively you can use site map plugins or look for a free sitemap generator that will create a sitemap for submission through webmaster tools. This is also a good way to produce a site map for websites with a lot of pages or complex navigation systems.
