Not to mention other known "Blackhat" spamming techniques that can hurt your site.

Depends on what you want to pay for it.

Obviously the value of a 4 letter domain depends on the letters and the buyer.

For example:

Loan.com would be far more valuable then DQWE.com

On the other hand if the buyer has a company named Deluxe Quantum Widget Experts then they might deem the domain DQWE to have some value over what the average potential buyer might be willing to pay for the 4 letter domain.

With all the variations of extentions and changes coming in 2009 its hard to put a value on .com generally. Specifically the value of a .com is mainly impacted on keyword, relavance to specific industry, ability to brand, meaning, and other factors, after all that - the shorter the better.

There are services that can help appraise domains such as sedo.com.  I would never base a business decission on an appraisal from sedo or other services like it, but it can give you a general indication of value (from a ball park perspective).

A) It can be important to SEO in the sense that it can help get all your content crawled. If you think about a "lazy bot" crawling your content and bouncing halfway through the page only reading a bunch of scripts and tables without seeing what is really of value on the page then yes... it can help.

B) Utilizing CSS can also give you manual control to prioritze content using zones.

C) In terms of PPC: Optimized CSS can also help pages load faster, which can contribute to PPC landing page quality scores.

D) Optimizing code with CSS overall can help your rankings, however I can say from experience that after optimizing some sites built previously on tables and converting the code to tabless CSS has in some cases helped and in others not made a difference at all.

I say its worth doing everything possible in your power to make your site more efficient for users and search engines.

this is the text. just for test

No it is not true!

Especially with geo focused results, country specific extentions should be the first choice.

Example .ca for canadian or .co.uk for UK based websites.

Also think about some of the strongest sites like wikipedia which is .org and other edu or .gov sites that dominate SERPs.

There is of course a high correlation between high rankings and .com domains - but most likely due to age and optimization. 10 years ago you probably would have registered a .com and now that short keyword rich domain has age and has probably collected a lot of backlinks and added a lot of content, making the site strong today.

In saying that I would still recommend a .com because people and browsers typically assume its a .com first - but it shouldn't be your only option. Use the extention that best fits your geo target and organization.

There is value to links that are No Follow!

•  They can drive traffic
•  Not all search engines utilize the code
