Everyone's partially correct.  Alternate attributes are for images only.  Title attributes in anchor tags can be used in links, however if you are performing SEO best practices, using title attributes in anchor tags is a first signal that you are probably spamming the search engines if not used with extreme caution.

Why?  Because the anchor text (the text you wrap the anchor tag around) should suffice to communicate what you're linking to.  Title text in anchors is best left to only be used when you're using them as a place anchor on a page, not as a link.

sites need regularly fresh content and inbound authority building.  So in this scenario, an internal blog would make sense and provide more long-term value than an external blog unless you've got another plan for a high volume of long term content freshness on the main site.

The exact match keyword domain aspect isn't as important as it used to be since Google has slightly devalued exact match domain importance.  Even when it carried more weight, it shouldn't be a primary means for long term success because it causes the illusion that a diverse strategy isn't as important as it in fact really is.

The founding principle to SEO is brand identification. The more you do to model your web presence after successful major brands, the more you will naturally earn trust and authority big brands earn. That in turn boosts all other aspects of SEO.

To achieve this specific to subsidiaries, you establish a parent company corporate site, and a stand-alone domain for each subsidiary.  Every site however, needs to utilize the most sustainable SEO methods possible. You can't just slap up sites with a few pages and expect them to rank or pull in highly qualified visitors without serious focus.

Only link back to the parent company site and other subsidiary sites from your "About", and "Contact" sections unless you believe it's valuable from a visibility perspective to link from every page. HOWEVER if you link from every page, they should be nofollow links. if you do mass volume links from site to site and they're not nofollowed, that leaves you highly exposed to potential algorithm penalties.

If you want each subsidiary to succeed as its own brand you will need separate social channels for each as well.  Again though, they'll only be helpful long-term if you have the resources to maintain them in quality engagement ways.

There are many other rules and guidelines (like "keep duplication of content to as near zero as possible") however that's the core concept that addresses your question here.

I'm with Ash on the Internationalization strategy. I would also suggest that if you go with domain.com/countryspecificsection/ then each country specific section should have it's on country / language specific structured markup and Meta data assignment. This will help ensure Google doesn't have to figure it out on their own (because they are a gambler's nightmare as to how they can get mixed signals wrong).

Harald,

I need to challenge your response here.

You stated:

"Boost works not only for manual actions but also for algorithmic problems, like Penguin."

That's absolutely not possible.  Penguin is not baked into the main algorithmic process. it's a separate entity that only runs a couple times a year.  So unless the clean-up was done literally within a few days of the next Penguin update, the magic recovery you claim was NOT due to Penguin related problems.

Business listing directory environments have a big challenge when it comes to URL structure / information architecture and content organization because:

1. Many businesses are searched for based on geo-location
2. Many of those require hyper-local referencing while many others can be "in the general vacinity"
3. Many other businesses are not as relevant to geo-location

So what is a site to do?

The best path is to recognize that as mobile becomes more and more critical to searcher needs, hyper-local optimization becomes more critical.  It becomes the most important focus for SEO.

As a result, URL structure needs to reflect hyper-local first and foremost. So:

• www.askme.com/delhi/
• www.askme.com/delhi/saket/
• www.askme.com/delhi/saket/pizza/
• www.askme.com/dehli/saket/pizza/pizza-hut/

This way, if someone searches for "Pizza Hut Dehli", all of the Dehli Pizza Huts will show up, regardless of neighborhood, while anyone searching for "Pizza Hut Saket" will get more micro-locally relevant results.

And for those businesses that serve a wider geo-area, even though they too will be assigned a hyper-local final destination page, they will still be related to their broader geo-area as well.  So someone searching "plumbers in Dehli" will get the right results and then they can choose any of the plumbers in Dehli regardless of what neighborhood they are in.

Note how I removed /search/ from the URL structure as well. It's an irrelevant level.

having the clearer understanding about the concept of having multiple "titles" on a single page (an H1 headline is the in-content "title" for that page), David is correct - while HTML 5 allows multiple H1 tags on a single page, this is bad because the H1 communicates "this is the primary topical focus of this unique page".

Because of that, if you have headlines within the content area for content elsewhere on the site, and link to that other content, then those are absolutely best served with H2 headline tags, or if not , then at the very least, "strong" tags if the topic of each target page is significantly different than the primary topic of the page they're all listed on.

Whether you include the sub-nav in the site-wide navigation as drop-downs or not, make sure that you also have that sub-nav as on-page links (such as in a side-bar) specific to each section.  So that only that sections page links will then be on all of the pages just within that section, without the drop-down needing to be used. This ensures proper attribution and relationship queues for SEO.

Having said that, this issue is widely debated in the industry.  I've seen arguments on both sides claiming they have proof that one or the other of your choices was better.  Personally, I've always taken the approach that SEO should always be balanced with usability.  So when this question comes up I don't tell clients to kill the site-wide drop-downs.  Instead, I focus on other refinement (like the section by section dedicated side-bar links, and proper breadcrumbs, and in-content links, and so forth).  And that has always gotten my clients solid results.
