Which TLD

Which top-level domain (TLD) to choose?

By Clare Lawrence 10th March 2003 Clare isrepparttar CEO of Discount Domains Ltd a leading UK Domain name registration service.

I am often asked this question. Is it possible that search engines such as google give preference torepparttar 107761 .com TLD? Or are TLD’s all treated equally?

As a test I picked a random phrase “Technical services” and did a search on Google.com.

The results:

1. .org 2. .com 3. .com 4. .net 5. .co.uk

Tryingrepparttar 107762 phrase again using Google.co.uk (I am UK based) .

The results.

1 .net 2 .co.uk 3 .com 4 .co.uk 5 .org

Hopefully these results show that there is no preference given by search engines.

However there are far more .com domains out there than other TLD – users will be more likely to key in your domain name and addrepparttar 107763 .com extension themselves out of habit.

If your market place is local then your regional TLD can be helpful, this is because a lot of Search engines and Directories such as Google and Yahoo – offerrepparttar 107764 user a choice of “Searchrepparttar 107765 web” or “Search locally e.g. UK”

Having a local TLD can therefore be a benefit.


Some directories will use your TLD to categoriserepparttar 107766 geographic content of your site, and therefore exclude a site from inclusion solely because it does not match their local market.

The Open Directory (Dmoz) lists sites by both regional and market segments as Google usesrepparttar 107767 Open Directory in part for its indexing – your choice of TLD will have a bearing on whether your site is selected in a local search e.g. Searching Google.co.uk for UK domain name registrars will bring up our site www.discountdomainsuk.com because it is UK based.

The TLD can therefore have some bearing on how a site will be indexed.

Keywords in your domain name

Search engines such as Google do give some preference to keywords within a domain name, andrepparttar 107768 first keyword inrepparttar 107769 description and Title tags, so if your site’s domain name is www.searchenginedirectory.biz, your site will most likely fair better in searches for search engines than ones without keywords inrepparttar 107770 name.

Transcendental function programming

Written by Charles Douglas Wehner

Programming and chess have much in common.

Those who delve deep intorepparttar mysteries of chess will have discovered that a single move can alterrepparttar 107760 entire game. The ramifications go deep. Each subsequent move (or "ply" inrepparttar 107761 jargon) is conditional upon what went before, andrepparttar 107762 great chess-masters of this world pride themselves in being able to evaluate several ply of consequences.

The elegance of a game of chess is estimated fromrepparttar 107763 efficiency by whichrepparttar 107764 player heads towards his goal. No move must be wasted. There must be no hesitation. There must be no turning back to correct an error. Inrepparttar 107765 final stages -repparttar 107766 deeper ply - one seesrepparttar 107767 reasoning behindrepparttar 107768 earlier, seemingly trivial moves.

Thenrepparttar 107769 game is over. There is a glow of satisfaction, but nothing more. Perhaps, however, there are books written forrepparttar 107770 guidance of others - that they also may knowrepparttar 107771 feeling of achievement. Yet inrepparttar 107772 final analysis it is a GAME. Passions may be aroused, devotees may consider it to be a religion, a philosophy,repparttar 107773 highest accomplishment of human intellect - and still it is a game.

Machine code programming has all these facets - and delivers a PRODUCT as its goal. It is a game and an industry combined.

The programming ofrepparttar 107774 transcendental functions involvesrepparttar 107775 use of mathematics. There are various polynomials forrepparttar 107776 creation of sine, cosine, tangent,repparttar 107777 logarithm and antilogarithm. Slavish obedience to set rules may well deliver a working product - but is itrepparttar 107778 BEST?

Can you become a chess master by memorising a book?

Let us considerrepparttar 107779 McLaurin-Taylor polynomial forrepparttar 107780 natural antilogarithm. Do you take 1, then addrepparttar 107781 argument X? Do you now multiplyrepparttar 107782 X byrepparttar 107783 X and divide by 2 before adding it on? Do you multiply X by X by X, divide by 2, divide by 3, and also add on? Is thisrepparttar 107784 best?

Horner's rule says you can PRE-divide a large number such as 1 00000000 00000000 00000000 00000000 in binary (FFFFFFFF in Hex, 4294967296 in decimal) by 2, by 3 and so on, and build it into your code. Thenrepparttar 107785 machine does not have to waste time creating constants. The rule also says that you start atrepparttar 107786 end ofrepparttar 107787 polynomial and work backwards. So if you multiplyrepparttar 107788 last coefficient by X, and add onrepparttar 107789 penultimate before multiplying again,repparttar 107790 last will have X-squared in it whilstrepparttar 107791 penultimate will have X. So it costs only one addition and one multiplication per term.
