In layman language Web 2.0 means the second generation of web development. The first generation web development is considered to be the great dot-com bubble of late 90's and the rupture of which around late 2001 triggered ubiquitous reactions that the Web was over hyped. Concept of second generation of Web development started after a media conference between O'Reilly and MediaLive International. In this brainstorming session it was realized that the web has thrown up more interesting applications and Web technology has emerged more important that ever and the word Web 2.0 was coined. Web 2.0 is a business revolution making a bent towards the web as a platform. Web 2.0 doesn't have a definite boundary and there are several things encompassing a core. Web 2.0 is visualized as principles and collection of numerous sites running on those principles at some distance from the core.

Since then Web 2.0 has remained a top level discussion for proper definition and boundary that is yet to be reached. One can simply say blogs, social bookmarking, wikis, podcasts, RSS feeds, and lightweight business over a single platform. Web is no more one way, now uploading, and downloading of information happens simultaneously, sharing and distributing contents across networks leveraging the power of "Long Tail".

Web 2.o includes numerous practices. Here are some typically implemented practices by websites:

• Well-off internet applications based on Flex or Ajax.
• This intend to allow information intended for end-users, such as contact information, calendar events, geographic coordinates, content life, social relationships etc
• Presentation is separated from content through Cascading Style Sheets (CSS).
• High-end APIs (Application programming interfaces).
• Content Syndication through RSS or Atom.
• Facility for content creation through users, also by machines from client side or server side.

Content Syndication: Syndicating partial or whole content through standard protocols such as RSS, Atom, and RDF by using XML so as to be used by the end-users for their need.

Some misconceptions on Web 2.0:

• Curvy designs (This curvy structures became widely popular at the same time, designers also started making more websites with this cool looking styles)
• Use of Ajax or Flex (Which happens to come in the same time of Web 2.0, No doubt that websites with web 2.0 architecture needs these to work well.)

Web 2.0 is not an alien to criticism and had its fair share. Here are some criticisms leveled at Web 2.0

• Web 2.0 is not a new version of World Wide Web at all. It merely uses the technologies and architectures of Web 1.0.
• Ajax is not substituting the HTML protocol; it's an additional layer over HTML.
• Blogs or social networking was features of Amazon.com since 1995 when the word called Web 2.0 dint exist. It's way more than only blogs and social networking.

So, you've bought your domain, got some hosting. Now what? You need to make sure that your web site is as friendly as possible to the search engines so that they send you some traffic. This process is called "search engine optimization" or SEO for short. It is probably the most important - and most neglected - part of web site development.

Here are some tips to help your SEO web site development.

1. Don't use frames

Frames may help you to control the layout of your site but they are a nightmare as far as the search engine robots are concerned and will make it difficult for your site to be crawled by the search engine spiders.

2. Make sure there's text on your pages

This even goes for the page featuring that expensive Flash movie that you're currently forcing visitors to your site to watch (or more likely press the "skip intro" link). Search engines don't know what's written on images or animations. They can only read text (the images search is their best guess based on the text on the page and the video search is based on the description of the video). So make sure they have text to read!

3. Separate style and content

This means using CSS as much as possible to control the layout of your pages. That way the spider can read more of your content if all the "this is how it should look" stuff is self contained in its own CSS file. The biggest snag with this is that CSS needs to be really well written if it is to look nice at different screen sizes, on different browsers and with varying amount of text on the page. Test at least in Internet Explorer and Firefox and play around with the width of the browser to see how well or badly your site copes.

4. Use a title tag

HTML design programs are good at putting in really generic titles such as "Page 1" or "Home Page" but they're almost certainly not what you want the search engines to think your site is about. Change the title to something meaningful. If possible make your title catchy and make sure it's short enough to be completely displayed when the search engine results are shown. This is basic SEO but you'd be amazed how many people don't do it.

5. Put in a meta description tag

Despite what you may read, the description tag is useful. It isn't often taken into account when Google or whoever decide which results to show, which is why some people say it isn't important. But it's normally used as the extract that's shown below the blue clickable link to your site. So if it says "XYZ home page constructed with Dreamweaver" instead of something interesting, that's what will likely show up below your title. And if it's blank, you're giving the search engines free reign to put whatever they want there.

6. Keep it simple

Spiders like simple. Despite all the advances in the internet, they're fairly dumb and the easier you make it for them to understand what your site is about, the more they will reward you.

So you are passionate about a particular subject and you want to take your passion online. At this point you may not know where to start and this is where I hope I can help you. After all you deserve to share your passion with others and they will benefit from it also.

The key to building any website is to build it with your visitor in mind. What can you truly do for them that will add value to their experience when visiting your site? Let's take for example that you enjoy building model planes. The first place you are going to visit is the online forums.

The reason I choose forums is because this is where conversations take place relative to any given topic. This will give you a measure of interest. The first step is to see how up to date the forum is and secondly how many posts it receives per day. Additionally how many people respond to those posts on any given day?

Obviously the more the better, the more interest the better for you. The next thing you are going to look for is, what are the questions being asked and can you engage in the conversation and offer solutions. If this is the case your next task is to look for keywords. What keywords do people use to seek out solutions for their needs?

The next thing to do is look for a keyword tool. I am going to use Google's keyword tool for this example. Keyword tools by the way are not by any standard of the imagination an exact science. They give you a rough guide as to how many times a given keyword is searched. So do not think that the numbers you get are exact.

Your task right now is to develop a list of keywords.

Once you have this list you are now going to look at the level of competition. Starting out we do not want too much competition but remember competition is good as it means there is money to be made in that market.

We at this point are just looking for cheaper ways to enter the market. To do this enter your keyword into the search box in quotes. Then check how many websites are coming up for that keyword. If it is in the millions that is not good if it is in the thousands then that is great.

You will now be refining your list based on competition. Once the list is completely refined you will now have the general structure of your site. These keywords will make up individual web pages.

To conclude this is how to lay the foundation then once you have these keywords you will be ready to structure each of the pages on your site using each individual keyword with content relative to that. To learn how to put all this together select any of the links provided.
