How The Google Search Engine Works

When you input a query into the google search box for example, you get a list of web results that contain that term. Users normally tend to visit websites that are at the top of this list as they perceive those to be the most relevant for that query. Have you ever wondered why some of these websites rank better than their counterpart’s? It is because of a web marketing technique called Search Engine Optimization – or SEO for short.

SEO is a technique which helps search engines find and rank your site higher than the millions of other sites in response to a search term. SEO thus helps you get more traffic from search engines like google.

This post covers the information you need to know about Search Engine Optimization and the google search - what is it, how does it work and the differences in ranking on the main search engines.

How Search Engines Work

To learn SEO you need to understand that search engines are not human. Although technology advances rapidly, search engines are far from intelligent creatures that often can’t feel the beauty of a cool website design or enjoy pictures, sounds and movies. Instead, search engines crawl the Web, looking at website text, to get an idea what the site content is about. This explanation is not the most precise because as we will see next, search engines perform several activities in order to deliver search results – crawling, indexing, processing, relevancy checks, and retrieving.

Initially search engines crawl the Web to see whats around. This task is performed by a piece of software, called a crawler or spider, the Google one is called Google-bot. Crawlers/Spiders follow links from one page to another and index everything they find on their way. Bearing in mind the number of pages on the Web - at the time of writing over 22 billion- it is impossible for a spider to visit a site daily just to see if a new post has appeared or if an existing post has been modified, sometimes spiders may not end up visiting your site for a month or so.

After a post is spidered, the next step is to index the content. The indexed page is stored in a massive data center, from where it can later be retrieved. Essentially, the process of indexing is identifying the words that best describe the post and assigning the postto particular keywords or phrases. For a human it will not be possible to process such large amounts of information but generally search engines like google or Bing deal just fine with this. Often they may not get the meaning of a post right but if you help them by optimizing the post, it will be easier for them to define your posts correctly and for you to get a higher rank in return.

When a search request happens, the search engine looks at it. It compares the search string in this search request with the indexed pages in it’s database. Since it is likely that more than one post contains the search string, the search engine starts calculating the relevancy of each of the pages in its index with the search string.

The top search engines use various algorithms to sort for relevancy. Each of these algorithms give various weight for common factors like keyword density, links and meta-tags. The reason why google and bing serve up different result pages for the same search string. It is a known fact that all the big search engines, like Google and Bing change their algorithms and if you want to stay on top, you also need to adapt your posts/pages to their latest changes. This is the primary reason to devote a permanent SEO strategy, if you plan on staying at the top that is.

The final step is retrieving the results. This is nothing more than simply displaying them in the browser, the endless pages and posts of search results that are sorted from the most relevant to the least relevant of websites etc.

Are Their Many Differences Between How the Main Search Engines Work?

Although the standard code of operation in all search engines are the same, the minor differences between them lead to major changes in results relevancy. For different search engines, different factors are most important. It is a fact that the major search engines like different content and if you plan to conquer more than one of them, you need to use search engine optimization carefully.

As a general rule Bing tend to rank posts/pages through mainly on-page keyword factors, while for Google links are very important. Also, for Google sites are like wine, the older, the better, while Yahoo! generally has no expressed preference towards sites and domains with tradition. Thus you may need more time for your site to mature to be admitted at the top of Google, as apposed to Yahoo!

Here’s a basic video from Matt Cutts about how the google search engine works from a simple keyword search.

A Review On The Vodafone Mobile Connect Service in Spain

Whatever you do think carefully before using Vodafone Mobile Connect in Spain, I think you can tell where this review is heading.

Never since the Internet was founded have I witnessed a slower and more unreliable Internet connection than Vodafone Mobile Connect, please read on as this may save you time and money, along with almost endless frustrations, so lets move on.

Around half the time with Vodafone Mobile Connect I see errors, the most common happens when plugging the Vodafone dongle into a USB port, the aptly named “no device” error, additionally I often see the “no services” or “no 3g connection available” error, these are just the common ones by the way.

It doesn’t even matter if your standing under the Vodafone mast in Alhaurin el Grande, you could be radiating yourself to the point of glowing in the dark, you wont get a great signal, it also doesn’t matter what computer OS you use either, from windows xp to windows 7 ultimate, the problems are equal. Don’t think the errors are anything to do with the type of contract you may be on, Ive tried both the payg and business and the issues remain the same.

Here in Alhaurin, the Vodafone shop staff have been known to tell customers that the Vodafone Mobile Connect Business pack is “unlimited”, what this really means is that you will not have any additional costs when the monthly bandwidth limit has run its course, this currently stands at 5gb, but as you can’t get a connection most of the time you will possibly never reach this limit, so technically they are correct, after further inspection at the Vodafone ES website theirs no mention of any Unlimited contract anywhere, not good for business that.

I have personally used more bandwidth on a Garmin Sat Nav travelling from Alhaurin to Fuengirola, perhaps Garmin should rise to the challenge and start up a mobile Internet company, it got me from A to B.

What about the 3g connection? …….the cheaply made Vodafone dongle often said 3g but sadly when you run a speed test you are likely to witness the whimpering slow speeds of 0.2 megs, all via this amazing 3g technology and that’s 80% of the time.

Another cruel joke from Vodafone Mobile Connect is that the usb dongle will change connections at random times, this leads to endless connection drops remember dial up folks, my Internet connection speeds went from slow to slower to slowest, no matter how you configure it. You can configure it to connect to 3G only, but this has no effect on it jumping ship and randomly switching services and connection speeds whilst browsing, from High-Speed Downlink Packet Access aka HSDPA, from 3G to HSDA and often finally settling at GPRS.

For anyone who has never used GPRS to load up web pages this is a painfully slow connection.

Website page loading times using VMC are often as slow as if you had written the content yourself, you could click on google and tick only show the results from the last 24hours, and by the time the results page has loaded you would be staring at last weeks news. I think you get the point.

My final issue with the Vodafoney Mobile Connect dongley is the install of the software itself, this involves just basically plugging it into a usb port the software is on the dongle, clever and simple you may say, but hang on a minute… what is that spy-ware like software its installing on my laptop. Vodafone install a key in your computer registry that logs wherever you visit online, with this they can now report your browsing habits, it even uses your bandwidth to send this data back to them, you may ask where’s the box to tick to avoid this un-neccessary logging? well it’s nowhere to be seen during the install.

If you look really hard and i mean hard, you will find somewhere on their forum on how to disable this function, their are several posts from customers requiring this information, one post from a moderator gives you the completely wrong info and he clearly should be working at the Vodafone store in Alhaurin, in this particular store their answer to any technical issue is to make you wait several weeks for a new plastic dongle, coincidentally this has the same errors as the previous one.

If your an existing Vodafone Mobile Connect user and you would like to turn off the pre installed reporting function, here’s how yo do it. Simply open the windows start menu and type regedit in the search box, look for the Vodafone folder then the VMC folder, look at reporting as this will be preset to ON, feel free to change this by typing OFF if you like.

In my opinion Vodafone should be held accountable for this, at least Rupert Murdoch’s News of the World finally admitted to tapping into telecoms, surely Vodafone are capable of putting an optional box to tick during the install of your dongly thing, wasn’t it Bill Gates who got into trouble forcing Windows users to install IE along with every OS, i’m sure some customers would rather not share there browsing habits online.

And what are the costs for this amazing service?

Vodafone Mobile Connect Business is nearly 50 euros a month.

My Rating 0/5 : AVOID VODAFONE MOBILE CONNECT LIKE THE PLAGUE
