Wordpress is one of the most popular software app. You can find many Wordpress websites just about anywhere. Even I myself am using Wordpress for my blogging and website creation. It is very versatile.
If you want to build a free website using Wordpress, you can get one at Wordpress.com and sign up for an account there. However using a free website in Wordpress.com may not be the best option. Ok, ok, I should be supporting Wordpress, after all they do provide free download of their software to be installed into your paid hosted website.
And for those who don't want to pay for anything and still like to use Wordpress as their blogging platform, they can build a free website by signing up with them.
But as your needs grow, you will find the free offering is not as versatile as say Google's Blogger/Blogspot in that you can't place any advertisement into your Wordpress blog account. However Wordpress do provide some premium offering to increase your requirement. It took me a while to finally find out the price. Wordpress did not display their premium pricing publicly and I only found out about the pricing after deciding to explore their free Wordpress blog by signing up.
The premium offering can be cost effective as you are just picking up what you want as your needs grow. However in the long run if you are adding up each premium offering, you may end up paying a lot more than just going straight into a paid hosting with a Wordpress installation.
All the offerings are on a per year basis. And if your needs is not a lot, perhaps you just need to add a domain and Custom CSS that comes to about $29.94 per year.
And that was just what my friend did. He got a domain from GoDaddy and pointed it to Wordpress.com and used the mapping functionality which cost $9.97 and bought the Custom CSS for $14.97 so that he could modify the them to include some Google Adsense in his Wordpress blog.
So he has just plunk in his money for nothing. Although there is a refund policy of 30 days, but I think he may have exceeded the days after trying it for some time.
So in the end, I advise him to get a paid web hosting. There are many cheap and good web hosting companies around to choose from. It is not always that you need a lot of bandwidth and storage space. So a simple and cheap web hosting account might be all that you need as you are starting out. You can always upgrade later if you need more space and bandwidth transfer.
There are always some pitfalls when trying to build a free website. But if your needs are simple, free is good. But if your website ambition is to blog to promote yourself and your work, it might be better to go for a paid hosting. The upgrade offering from Wordpress.com just didn't suit my friends requirement. And if you planning to go for free now, and then thought perhaps later you want to upgrade to expand your website functionality then you need to think carefully about what you want to do with your website.
If it will tie in with your work and business later. Then don't try to build a free website. Go straight to building one with a paid web hosting company.
And of course if you want to really succeed in building a website, try Sitesell Site Build It. They have the best tools for creating a successful website. And of course, it cost a mint, but it is worth every penny. Scrimping initially won't get you far in the long run. Better to jump headlong into it if you know the direction you are heading.
