Let's see if someone knows how to fix this.

Issue 1:

Menu items link to the same url in the English and in the Spanish version of the site.

For example:

In the English version, the menu item: One Bedroom, links to:

http://domain.com/index.php?option=com_hotproperty&task=viewtype&id=11&Itemid=31

instead of:

http://domain.com/index.php?option=com_hotproperty&task=viewtype&id=11&Itemid=31〈=english

(note it has the language definition)

in the Spanish version, the same menu item (Un Dormitorio), links to:

http://domain.com/index.php?option=com_hotproperty&task=viewtype&id=11&Itemid=31

and should link to:
http://domain.com/index.php?option=com_hotproperty&task=viewtype&id=11&Itemid=31〈=spanish

So basically Google has no way to know which is the Spanish version and which is the English version.

Issue 2:

The other problem is that all pages have the same title tag: Buenos Aires Apartments – Temporary Rent – Furnished.

We only want this in the home page but for the rest of the pages we want unique title tags.

Solution?

Not sure, we've been through this before. One cheap solution I can think of is nofollowing all links from the menu so the spiders are left with the sitemap alone to spider the site: http://domain.com/sitemap.html

But this doesn't solve the issue with the title tags.

I am looking for advice from an expert to solve these issues and every page has its own URL and Title tag

Issue 3:

Client wants to turn on the HP Mosets function to allow “agents” to upload their own properties, and charge them $ for that. This is an inbuilt function of HP Mosets.
