What is The Deep Web?
Internet
Search engines have crawled and indexed hundreds of billions of pages on the web, but this is just a fraction of the true size of the content available.
Search engines browse the web looking for pages. They look for links and follow these links, always on the hunt for pages to index and they are very good at this. They are not very good at finding pages with no links to them though. They can not perform searches on websites they way we would, and so have no access to content that is generated on the fly by a search or form that a human would use.
The deep web is the content that search engines do not have access too.

How do I Optimise My Website?
HTML
The trick to good Search Engine Optimisation is to forget about search engines and focus on visitors.
Make your site clean, clear and to the point. Use proper HTML coding practices. Ensure that each page has a relevant title, relevant description, relevant keywords and original content.
Give each image an alternative text and a title. Highlight important texts in bold or italics.
Have an easy to understand navigation system as well as a sitemap.
In general, keep it simple for the visitor to use and understand. Make it the kind of site people will want to visit to get answers and the search engines will want to rank your site more highly.
There is a lot of talk about back links. These are links to your site from others. These are important to search engines and they will come if you create the type of site talked about here.
Google has written more on the subject of SEO and produced a starter guide.

What is SEO?
Internet
SEO or Search Engine Optimization is all about making your website’s content and topic as clear as possible to a search engine such as Google. It is about showing the search engine that your content is very relevant and should be ranked highly.
It is a field full of big words, the unscrupulous, miss-direction and confusion because everyone wants to be at the top of search results and so people are willing to part with money in order to do so.
If you are unfamiliar with SEO, all you really need to know, and here is the big secret, is that Google, Bing, Yahoo and all the other search engines want to provide a good service. They are fighting tooth and claw to get people to use them. For this reason they each want to be the one that provides the best quality websites for every search a person makes.
So the secret is that they will rank highly a website that a visitor will find useful.
That is the whole trick to SEO. To rank highly with search engines, create a website that people, not computers, but humans will appreciate.
What is a PNG File?
Design, Internet
PNG or Portable Network Graphics files are bitmap images using lossless compression. They were designed to replace GIF image files but have taken a long time to become commonly used due to a lack of support by the Internet Explorer browser.
These issues have now been resolved and the format is quickly taking the place of GIF files where animation is not required.
This type of image is best used with none photographic images that use sharp lines and blocks of colour. They do not compress as well as JPEGs but neither do they lose any quality in compression.
The best use for PNG files is where an image needs to use transparency. Although an area of a GIF image can be transparent, they can only use up to 256 colours and only one level of transparency, while PNG files can use millions of colours and have varying levels of transparency. For this reason a transparent area of a GIF file will be jagged and pixelated while a PNG file can be smooth or fuzzy in order to blend in seamlessly with its background.
What Does Google It Mean?
Internet
This is a modern colloquialism for using a search engine. When you google something, you search for something using a search engine such as Google or Bing.
What is a Search Engine?
Internet
The Internet is huge with billions of files and pages in every language and on every topic. For this reason people decided to index it to make it easier to find what you are looking for. At first this was done manually but due to the explosion of content, people could not keep up and automated search engines where born which would crawl the web looking for new content and indexing it as best they could.
These crawlers also called web bots are just servers that read the content of pages like we would read them using a web browser. They try to work out what the page is about, and then index them.
When you go to a search engine such as Google or Bing, you are presented with an input box where you type what you are searching for. In the test you submit, the search engine then trawls through the billions of indexed pages to find a best match to your query.
Today Google rules the search engines but there are many to choose from and although Google is the biggest, Bing and Yahoo also do a great job of it.
Over the years they have become very sophisticated and good and guessing what you are after. They try hard to make it very simple for you, allowing you to type in a question, and then present you with a list of pages the search engine thinks you are after.

What is The Web?
Internet
The Web or World Wide Web (WWW), is the part of the Internet made up of web pages with links (hyper links) to other pages on the Internet and written in a language called HTML which you need a web browser to read properly.
If you go to just about any website you will be taken to a page known as the homepage and from this page will be links to other pages. This simple concept of pages linking to other pages is the World Wide Web.
The web as we know it today was created by British engineer and computer scientist Sir Tim Berners Lee.
It is common to add the www prefix to domain names, but becoming less so. More often than not, you can leave out the www portion of a domain name and still get to the same website. The www part of the domain name is called a sub domain.
