The book "Building job sites with Joomla!" concerned primarily only one issue, the construction sites with job offers. It's true that the author added some more general topics such as about SEO, but do not change the fact that it is addressed to a very narrow audience.
The first chapter I was very disappointed, as usual, several pages how to install Joomla! and ... how to install the commercial component of Jobs!. The author wrote only that it is commercial, and gave the address page. I wish I had made an effort to specify exactly why he chose this instead of another extension, because we have more than one (ex. JA Job Board) to build this kind of web page.
And was any word why Joomla! is the best possible CMS, the construction of such sites, because there is some scripts build ony for this.
Thus the impression that the subsequent chapters is simply advertising and documentation of this component, not a case study site, which is already working on this component.
Chapter 3 what about how build a template, it is quite chaotic and too little practical, looks like a rewritten documentation. There are a lot of unnecessary information, and is not the most important, being guided by building or selecting a template for such sites.
The next chapter is about the administration of a duplication of information from other books for beginners.
I think a person who reaches out for the title already knows the basics of CMS, therefore, considers it a waste of paper.
The last chapter of SEO - is also weak, the author mentions only one extension, as if forgetting the other, in my opinion, more useful for administration of Joomla.
Information were also taken notice, and where this whole marketing and HR coating. In a word, I'm disappointed. Only 2 or 3 chapters are useful with description extension, but the rest of the content is very far-fetched, sorry.
