XML Sitemaps are compatible with many types of Google

Since 2005, the site owners were able to get their Sitemaps to improve the indexing of their site content. Submit an XML sitemap is basically like to take your site to Google and say "Hey Google". See how my site is nice.
It is a great advantage, because most of your site that Google indexes, the better for your sites potential investments. As a Sitemap index has evolved, users submit multiple specialized formats sitemap, video and image content geo sitemaps XML. With all these different types sitemap Google has finally taken it upon themselves to provide support for multiple types of content type XML Sitemaps. But is it really worth?
This change will allow users to submit site maps to collect a number of types of content such as images, geo-and types of video content. This should speed up and facilitate users to get some info on the Google site to index. The following example from Google:



http://www.example.com/foo.html

http://example.com/image.jpg


http://www.example.com/videoABC.flv
Grilling tofu for summer



Drawbacks
Unfortunately, although the effectiveness of Google is XML support has some disadvantages that may result from this change.
Presentation of multiple Sitemaps allows the website operator to distinguish the separate data indexing. Google Webmaster Tools allows users to view the status of your map site content indexing, and condensing all this information may jeopardize your understanding of how Google indexes your site. Keep sitemaps for individual data types allows the user to more accurately measure what percentage of the different types of content on Google is indexing, allowing you to work on improving this.
Is it effective?
So you might think even less understanding of sitemaps make a little ,more turbid, at least itis less work and more effective. Well, yes and no. Sure, it requires less to download site map generation, but most of the time sitemaps are automatically effective enough (or produce or upgrade) for a small difference can be found in time.
Another aspect is neglected by many as the restrictions on the entire URL and sitemaps (50000 URLs, and 10 MB in size). Condensing various types of information the site can see a number of sites exceeds the limit.
End of Alliance
One final point is that this rate yields sitemaps.org alliance with Microsoft and Yahoo. This rule has been solved long ago to allow indexing formulas Sitemaps across the board which makes it easier and more efficient in submitting Sitemaps for each search engine providers.
This change, Google has virtually ignored this agreement and causing compatibility problems Sitemaps performers through a variety of ways. So even though this change seems to XML indexing performance in the longer term, it can be more difficult than it is.
Stick with what works
Instead of falling with the latest formats, site owners would be better to stick to multiple sitemaps unique content. Frankly, they will always be indexed to the same level as the contents of multiple sitemaps, but with the added benefit of examining more complex in webmaster tools, and compatibility across the board. If it is not broke do not fix it.
