Are PHP includes Search Engine friendly?

The answer is yes they are. Because the PHP includes are handled on the server side and the are turned in to HTML files before being send to the browser, or search engines. Search engines will not even know there is a include there.

This is a answer to a email, the person left no name.

The title is to simple its the age of the domain. But are old domains better?

Yes is the answer, why? Because most hacks / spammer use throw away domains, which are only used for less than a year because they are shut down. And for this reason search engines give a little more proirty to domains that are old.

When getting a domain name most people use there personal name, business name or a word that has meaning to them only. What you need to think about is how the domain is good for seo.

People will pay billions for the right domain. Business.com is valued at more than $300 million. Is the right domain worth it?

Buying a domain with you keywords in will not get you to the top of Google and other SE. But crawlers with like the related to content keywords.

Don’t worry if you have got a ‘wrong domain‘ as such. Domain naming is only a bit of seo strategy. You can make up for it with other kick ass seo.
