Web Development and Reverse Engineering

Web developers are always trying to create attractive and functional websites. If you are using a content management system you need no special knowledge of web technologies to create basic pages. But sooner or later you need to modify layout or some part of the website for which there are no settings in the user interface. Modifying code means knowing basics of HTML, CSS, JavaScipt, PHP and other languages used for websites. If you are new to this world you will need some tutorials and introductory texts to learn basics of web technologies.

However, there is another way of learning with possibility to experiment and test various modifications of the code or layout. It is called reverse engineering and means examining code of an existing page. Every web browser has a function to display the source code of displayed page. By examining it you can see what elements are needed to construct the web page. This is a great way to learn HTML and CSS language. Of course, examining and understanding how it works is one thing, creating your own project is another. The easiest way to start writing code is to make small modifications on your website. For this purpose you need a development installation on your home server, because experimenting with a live website is not a good idea. Depending on the system used for your site you will have to find files which contain the code for the page under examination. There is no general rule, but the main core of the page layout is probably in some template file.

This approach of examining the source code is also useful when you find a page with some fancy design or cool menu. To understand how it is done you need to find appropriate part of the code. Firefox, for example, has a nice feature to display only the source code of a small part of the website. You simply select the page elements you are interested in, click the right mouse button to display a menu and select View Selection Source. Once you find source lines responsible for the wanted page element, you can study them and try to implement something similar on your website. This doesn’t mean that you can copy the code directly, you will have to modify it to be compatible with your existing website. But the basic principle is that you examine existing code and experiment with small modifications. If you combine this approach with web resources explaining theoretical background of web technologies, you will be able to quickly understand and learn new languages and technologies.

The Role of SEO in Web Development With JavaScript

With the ever growing and evolving nature of the internet and the different websites you find online, it is expected to come across with a number of mixed messages along the way. One of the longest debated topics when it comes to the role of search engine optimization in web development is whether or not using JavaScript is a great idea when optimizing a website for search engines.

The online crowd is divided – some people firmly believe that Java should not be used at all, while others think that using JavaScript is essential and contributes a lot to the overall success of a website. If you are one of the many who is considering whether to use JavaScript on your website or not, this article will help you clear your head and let you see both the good side and the bad side of using Java and how it relates to search engine marketing.

One of the main reasons why a lot of website developers and web designers are big on JavaScript is its being simple and providing a lot of options for the website owner – Java is a relatively simple programming language that will let you create several web effects that is impossible for traditional HTML to do. On top of that, using Java in a website also provides a great solution to the common problem of code bloat.

Code bloat is a situation where the size of an HTML file used for a certain web page reaches its threshold, usually the limits set by the different search engines. When your website or even just a single web page on your website goes beyond the specified limits of codes, you will be penalized with a lower ranking in the results pages which is not good news.

On the other side of the fence however, a lot of web developers also think that applying Java will only harm your rankings simply because it makes it harder for the search engine web spiders to crawl on your website for indexing. Search engine crawlers already have a lot of ground to cover these days and crawling through overwhelming volumes of JavaScript codes makes it very hard for them to find what they are looking for.

Search engine crawlers look for keywords and relevant text and information in your website before it gets indexed and ranked, and if you have lots of JavaScript embedded within your website the crawlers will have a hard time figuring out if your website is relevant or not, thus harming your SEO strategy.

All things considered, using Java will not make or break your SEO strategy. As long as you have your online marketing strategy all planned out, you will not have a hard time deciding whether to use JavaScript or not.

Tablets: Another Consideration in Web Development

Let’s face it; many people are still not enamored with tablet PCs. Thousands may already own an iPad or any tablet but there are still plenty of individuals who choose the bulkier but more feature-rich notebooks or even netbooks. The tides of change cannot be stemmed though and tablets will become a major platform in personal computing in the near future.

As consumers, we can see that as an improvement over what we have today. But for webmasters and web developers, it poses yet another challenge. With sales of tablet PCs rising, the time is right to start investing on tablet-friendly website versions. Yes. Versions because you do not have to totally redesign your website to accommodate internet surfers using tablets. Like with smartphone users, you can specify a version of your site to be served to those using tablet.

When developing the tablet version of your website, here are some tips to keep in mind:

1. Keep file sizes to a minimum. In the future, all tablet PCs would be equipped with Wi-Fi functionality. Today though, plenty of tablet PCs still connect to the web using 3G networks. This means pages would not load as fast as when the PC is using Wi-Fi connection. As a result, you have to ensure that your website’s tablet PC version is light and would load easily. Most internet browsers are impatient and if you cannot deliver the info they need on time, they would easily hit the back button and try another website.

2. No Flash. Android-powered tablet PCs support Flash. Apple’s iPad does not. We can argue all we want that Android-powered tablets are better than the iOS-powered iPad, but it will not change the fact that sales figures are on the side of the iPad. That said, you have to find Flash alternative to use on your site if you need multimedia content on your site’s version for tablet PCs. Furthermore, contents using the multimedia platform from Adobe cannot be read by search engine bots thus lowering your chance to get higher ranking on search engine result pages.

3. Resolution and the accelerometer. Most tablet PCs are equipped with accelerometers so there is no definite resolution to target when designing for tablets. There’s another thing to consider with accelerometers. You have to design your site in such a way that no matter how it is being rendered, the area above the fold is well optimized. Above the fold means the area that the visitor can see without having to scroll down. Make sure that you make good use of this area in any resolution or display layout.

Remember that tablets are still relatively young and in the near future, they would come with better and newer features. Make sure that you are on top of these changes and adapt your site’s design to accommodate future changes.
