To get well written text, you need to invest some time, or pay someone skilled to do it for you. Both are expensive and slow exercises, so many SEOs choose to take a shortcut and “spin” articles. This generally involves taking one source text, and altering the language inside it to “create” a new article. The better spinning programs are aware of things like grammar rules, word frequencies in various languages, set phrases and idioms, and so forth. The worse – and predominant – spinners simply perform synonym replacement, which produces this kind of mapping:

“We walked to the large house” would be replaced by “We ambulated to the gigantic residence”.

The latter looks ugly, is awkward to read, and generally doesn’t fulfil any kind of quality standard – though it is different, thus helping create unique content, and the meaning remains pretty much the same. The massive failing here, though, that utterly defeats the goal of those using spinners, is how trivial the product is to detect.

In every language, there are common words, rare words, and everything between. The probability of individual words occuring in a piece of text is fairly constant, being skewed a bit depending on the document’s type and domain (agricultural reports will be more likely to contain terms about farming, horticulture, and plant and chemical proper nouns, for example). The core set of terms, and their frequencies, will remain the same.

The direct synonym replacement used by typical spinning programs (spinners) has two problems. Firstly, one must bear context in mind when picking alternative words. For example, “junk” (used as a noun) can also be:

“boat, clutter, debris, discard, dope, dreck, dump, flotsam, garbage, jetsam, jettison, litter, refuse, rubbish, salvage, scrap, ship, trash, waste”

Depending on whether we’re using this word to talk about a sailing vessel or a piece of rubbish, we can divide this set of alternatives into two distinct groups with different meanings. Simply using a thesaurus to pick a random replacement word will often change the meaning of a sentence. “I thought your product was a heap of junk” is not semantically equivalent to “I thought your product was a heap of boat”. Note how simplistic substitution also makes the sentence grammatically incorrect in this case.

The second problem with direct synonym replacement is that it doesn’t care about the probability distribution of words in a language. This always leads to the inclusion of rarer words, and exclusion of more common ones. In one above example, we used ambulate instead of walk; the former is a comparatively rare word. Using it makes the sentence more awkward, and harder to read (protip: always use the simplest language that you can).

Just to show how easy spun pages are to spot, let’s find one, and take it apart, then see how abnormal it is. We’re going to first find how frequent words are in English, and then use them to compare a spun article to a previous post on my blog.

The reference frequency list we use to represent general English comes from the British National Corpus. This is in British English, so we’ll make things fairer by Anglicising the spun document, making “color” into “colour”, “center” into “centre”, and “-ize” into “-ise”.

We’ll mathematically compare both the spun and un-spun text against this reference model of the English language. This can be done by first building a list of words used in a document, and then counting how many times this occurs in the document. Dividing the count of a word by the total number gives the probability than any random token from the document will match that word. We’ll also have a list of these probabilities from the British National Corpus (BNC). To compare this, we’ll take the absolute difference between measured and reference probabilities for each term, and express that as a percentage of the reference likelihood. As these percentages get pretty high, and to reduce the impact of any anomalous data, we’ll also measure the log of the difference measure.

Full dataset

We can see a few words sticking out here. Some give an indication of the document’s topic (SEO, copywriting) while others are quite bizarre (scruffily, overeat). The difference column shows the magnitude of frequency variation from what’s expected – a difference of zero means that a word occurs just as frequently in this text as it does in the British National Corpus; a difference of 100% means that the word occurs twice as often or half as often. Note how the words that stick out hugely aren’t that congruent as a set – overeating and scruffiness have little to do with copywriting, spell checking and proof reading.

Differences measured this way will be skewed rapidly by any rarer words that come into a document, and every document that has something to say will have to incorporate some topics using rarer that don’t fit the curve perfectly – this would be expected. So, using this measure, a non-zero difference score is inevitable; logs have been taken to smooth differences in scale. What is significant is where and how much the differences are.

The mean difference from standard English for the unspun document is 947349.85%, and the mean of the logs of the difference measure is ~1.46. These numbers show us how different the words in the spun document are from what would be expected in general language.

Full dataset

We can guess from the top differences here that the document is related to computing and fairly technical. The biggest differences in word probability are in the range of say 1e6 – 2.7e7, a lot less than the top four in the unspun document, which were from 8e6 all the way up to 1.4e8. The mean difference is half that of the unspun document (524475.55%) and the log differences again significantly smaller (1.18).

Comparison

For good measure, and to illustrate this point clearly, here’s a graph. The red line is the spun document, the blue one the unspun one. For a document that completely followed average word frequency, you’d see a line at y=0 (i.e., a flatline).

This shows that the spun document uses English consistently more unusually than the human-written (unspun) document; the red line is higher than the blue one, and the higher a point is, the more it varies from the British National Corpus’ survey of English usage. For reference, that covers ~10 million words in 4000 documents, so it’s a fairly good source of comparison data.

We all know about term frequencies (TF); it seems fair to guess that search engines have models of these, and that’s it’s not computationally intense for them to use TF as one tool to distinguish spam from useful content. When one can pick out spun content so easily (this system took ~40 minutes of coding and juggling in excel to make it look pretty, for one guy), there’s really no point bothering to add it to your site.

Of course, a sophisticated document spinner is definitely possible to construct. My point here is, the cheap and common ones only provide a massive bright flag that your site is spam. Avoid them.

Data

A full set of all the produced data, in a pretty and readable format, including the full keyword data, and a large graph, is available online here. The texts actually used for comparison are here (unspun) and here (spun).

If you feel like exploring English word frequences and getting into that long tail, I can’t recommend anything more highly than Wordcount.org.

According to Blogger’s help:
The format of the email address is username.secretword@blogger.com . Note that this email address must be kept secret.

Of course, a few of these have leaked into the public domain, onto mailing lists, which is why you see some sites at blogspot filled with ads for cialis and the like. One of these, for battlefornaboo.blogspot.com, is “robitforrock dot starwars at blogger dot com”. Enjoy!

One technique for measuring the propreties of words and phrases in text is n-gram analysis. This counts the numbers of single-word (unigram), two-word (bigram), three-word etc (up to n-word) phrases in a text.

E.g.: given the phrase “The cat sat on the mat”, we have the following unigrams:
The – 2
Cat – 1
Sat – 1
On – 1
Mat – 1
And the following bigrams:
The cat – 1
cat sat – 1
sat on – 1
on the – 1
the mat – 1
So how does this help us? Well, n-gram counts of large amounts of text tell us what the most common words we’ll find are. Once we ignore stopwords (the search engines will), we get terms that we can use as part of a search query to split up the results. If we know that “fish” and “knee” are common words, we could run two queries:
link:mysite.com knee
link:mysite.com fish
This would return 2000 links to mysite.com. Of course, some of these pages will have the words both “fish” and “knee” on, so there’ll be some kind of overlap, but we’ll still get say 1700-1900 useful unique sites. Once we have a good list to exploit, we can take the top 1000 results for our query divided up with 40 different ngrams to get a good 25000-35000 results – way past the 1000 limit usually imposed.

Implementing something like this would probably look like:

URL table – with unique URL field

query = “link:competitor.com”
for ngram in ngrams
for page = 1, page < 10, page ++
offset = (page – 1) * 10
results = getGoogleResults(query + ” ” + ngram, offset)
for result in results
sql(“insert ignore into URL values(?)”, result)

Of course, this is massively open to optimisation; post in the comments if you have any questions.

To help you out, I’ve included a list of over 700 of the most common English unigrams, derived from a good web-based source. If you’re interested in versions in other languages, or a longer list, let me know why and I’ll see what I can do.

I’m going to cover three methods of dealing with headers today – all quick, simple and powerful.

Perl’s LWP “HEAD” command

This is a commonly-found *nix command line tool, very simple in its operation, and likely already on your system. To use it, you simply enter “HEAD ” at the command prompt, where is the full address (e.g. including http:) that you want to check.

If you don’t have it, you can install this as root by whipping up a CPAN console (perl -MCPAN -e shell) and running i LWP::Simple – then just follow the prompts, and opt to install the GET/HEAD aliases.

Quick and simple – but it won’t report on redirects, just the final page, and you need root to install it in most circumstances.

Tamper Data

You can use Firefox to examine headers, alter HTTP requests, and find out precisely what every page is doing with this masterpiece of a plugin. If you’re using LiveHttpHeaders, I suggest you immediately exchange it for Tamper Data – just as light, and much more powerful. To use this, simply enable Tamper Data in Firefox, click “Start tampering” in the new window, and then visit the page you’re interested in; you don’t want to go playing with the server immediately, so simply accept the request, and ignore further requests. Tada – more information than you’ll ever need – including full request and response headers for everything on the page! This is also great for finding out FLV URLs and other things hidden by Flash apps.

Tamper Data has many additional functions, including page load optimisation, and far too much to cover here. Just check out this tutorial for a taster.

Command-line cURL header script

For a very verbose, quick, minimal and to the point solution, create a file called header somewhere on your *nix server, and fill it thusly (perhaps amending the PHP executable path):

#!/usr/bin/env php
$url = $argv[1];

function url_header($url) {
global $useragent;
global $timeout;
if ($useragent == “”) {$useragent = “Mozilla 8.0 +http://seorant.blogspot.com”;}
if ($timeout == “”) {$timeout = 20;}
$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_USERAGENT, $useragent);
curl_setopt ($ch, CURLOPT_HEADER, 1);
curl_setopt ($ch, CURLOPT_NOBODY, 1);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt ($ch, CURLOPT_TIMEOUT, $timeout);
curl_setopt ($ch, CURLOPT_MUTE, 1);
$result = curl_exec ($ch);
curl_close($ch);
return $result;
}

$useragent = ‘Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7) Gecko/20040614 Firefox/0.8′;

echo $url.”\n\n”; flush();
echo url_header($url);
?>

Make the file executable (chmod u+x header) and run with ./header

This will include the full details of redirects as and when they’re performed, and should get a reponse more akin to that a browser receives when compared to the LWP method, which uses a different useragent string.

There are two main types of web servers that can host websites and they are Linux servers and Windows servers. If you are setting up your hosting account yourself yourself, ask your web designer which type of server you’ll need to run your website. Sometimes it can be a hassle having to switch over from one type to the other which in turn could end up costing you more money. They both basically do the same things but certain e-commerce shopping carts, websites, CMS systems and other software will only run on one or the other.

The three most relevant types of web hosting for most businesses learning about the Internet for the first time are shared hosting, dedicated hosting and self hosting.

Shared hosting involves putting your website on the same part of a web server with other people’s websites. The equipment and server are owned and managed by the web host provider, with technicians on hand to monitor and manage the servers. This is a popular option because it is inexpensive and gives you many of the benefits that dedicated hosting provides. The drawback is that you will have limited access to the server which means you may not be able to run many of the applications you see on other websites. This is a good option if you just want to have basic website.
Dedicated hosting allows you to rent an entire web server yourself and have access to all its resources to host one or more websites. The website hosting company typically does not take responsibility for anything other than the hosting operations. Setting up files, databases, permissions and other technical things may (depending on the company) be your or your web designer’s responsibility. Most web hosting companies provide built in tools to make doing these things easier but the learning curve can be steep. This option is good for larger websites and ones used for e-commerce. If security is important then dedicated hosting is what you need. The cost can be a little bit more than shared hosting but there are many web hosting companies out there where there is no difference.

Self hosting is when you host the website yourself on your own web server. To do this you’ll need the proper hardware, software, technical skill and Internet connection. This option gives you complete control and responsibility over everything. Hosting your own web server will normally require a specialized Internet connection depending on your particular needs. Before going this route you’ll want to speak to an Internet consultant or IT person to get all the particulars.

When you sign up for web hosting you will given a login and password to your account so remember to write this information down and keep it somewhere you won’t lose it. You may even be able to sign up for hosting when you purchase your domain name. Speak to your web designer before doing this if you are not sure as to what you are doing or what type of hosting you need. If you don’t have anyone to consult with when you buy your domain name then purchase the hosting at a later time. It won’t cost you anymore to do so as hosting can always be added to your account later on.

Free hosting.

Free hosting usually allows you to create only the most basic sites, consisting of a set of HTML-pages. Sometimes you can use the built-in forums or guestbooks, however, very limited in its capabilities. For example, without registration, without possibility of moderate a forum or a guest. Neither of which content management system for free hosting and can be no question.

As for the operation of CMS requires php and mysql, then on free hosting will not be able to get. Besides hosting company that provides free hosting, most customers use websites to advertise. And opening a website on free hosting will have to accept the presence of it banners and pop-up windows. At the end of the domain name will be the third level (eg, your-sayt.narod.ru) and belong to the hosting company.

Free hosting makes sense to use for personal webpages (like me and my hobby), non-profit projects, as test sites. Major projects aimed at income or corporate sites, in most cases using paid hosting.

Benefits paid hosting.

Paid hosting – it is an opportunity to use all modern technologies for creating and maintaining web resusra. Inexpensive hosting site allows you to open a small or medium company or a small project. Major portals use the more expensive rate plans. But in any case, each project receives the quality service.

Even a low-cost hosting service allows you to use php and mysql (from one to several databases). Hence, the project owner will be able to install content management system (CMS), without which the setup and maintenance of an up-resusra converted into flour. In addition, the site will turn to high-quality forum, guestbook, add the popular scripts (eg, voting, feedback form, etc.). All this will do the project on low-cost hosting is much more interesting and more attractive than on a limited free hosting.

Important question – the domain name. Any paid hosting, including affordable hosting, allows second level domain name www.adres-sayta.ru (or net, com, org, etc.). This domain name belongs to the client web hosting company and is its property. In addition, to promote the site in search engines will turn only if paid hosting. For the promotion of sites on free hosting requires more effort, as search engines consider them to be less serious. In competitive demands on free hosting sites to break into the top ranks is almost unreal.

Thus, even an inexpensive hosting offers much more advantages than free hosting. Paid hosting – a measure of respectability and seriousness of the copyright of its owners. Also in the case of a paid hosting defines all legal issues related to ownership of the domain name and web resource. If you are strapped for cash, cheap hosting service allows you to open and successfully develop their own project in the network. Fortunately, the issue price is low – only 5-6 dollars a month.

Differences

On the various differences between hosting on Windows and Linux hosting on much to say, but within the most salient differences are:

The Linux hostings are mostly GPL, ie do not pay license and therefore is cheaper than an equivalent in Windows.

But he explained that although it seems that everything is free on Linux is not entirely true, we need a control panel for hosting by which the supplier has to pay. But equally there are panels open source, free to work as well in addition to cPanel, some examples are the Webmin and Baifo.

A Linux hosting using Apache and a Windows IIS. According to Netcraft, Apache is currently the market leader, is hosting the domains used in more uptime.

Apache is known for its security, but also IIS version 6, and in fact has never been “rooted” (hackeadada as root) although certain modules if IIS and ASP.NET. IIS is one of the safest web servers but does not reach the level of Apache although this has also had security flaws, like php.

At this point one could say that each of the respective operating systems and languages have multiple vulnerabilities and the study of OH Alhazmi and Y.K. Malaiya, “Measuring and Enhancing Prediction Capabilities of Vulnerabilities Discovery Models for Apache and IIS HTTP Servers”, predicts that more vulnerabilities were found in Apache IIS in the future. Although it is said that the reason to find more vulnerabilities in Apache IIS that it is because little commercial use of it, most Windows servers require nearly twice the processor and memory to process the same amount of information on Linux servers , hence it is a standard for Linux servers. Less hardware to the same, less costs. The advantage of Windows is that support services are cheaper and a Linux system administrator usually receives much more than Windows. They are more bugs in a system or vulnerabilities are detected is not bad. On the contrary, it means that each bug is found by plugging a new bug or security hole.

As many people can use php on a Windows hosting, but not ASP.NET on a Linux hosting, but many more who say this is false, simply MONO be installed asp.net applications will run on Linux without any objections, but many others say that these applications if they run but works just as well as Windows.

Finally we found that each of these operating systems offer a good service, each have advantages, both have been presented and also have multiple quantities of vulnerabilities, some already solved and other still undiscovered, giving the user the assurance that they are problems have resulted, just as the decision to use Linux hosting or Windows hosting should be based on the real needs of the project is developing.

My personal opinion is that unless an application to be exclusive and mandatory work on Windows, for whatever reason, one should choose Linux for the hosting.
