The primary thing to remember in creating a website is that you’re not creating the website for you; you’re creating the site for your visitors. If you have created websites on other software and now want to create one on WordPress.com software it’s important to fully comprehend the limitations of blogging on the WordPress.com multiuser blogging platform.
As WordPress.com is a multiuser blogging platform, all blogs wearing the same theme are using the same underlying template and we bloggers cannot access the underlying files and edit templates or themes. The only themes you can use on a WordPress.com site are those found here Appearance → Themes and described in the Themes Showcase. There is no upgrade you can purchase from WordPress.com that changes those facts.
Custom Design Upgrade
Two free WordPress.com themes, Sandbox and Toolbox designed to allow maximum flexibility for CSS editing and creating new “skins”. Toolbox is more modern and includes support for CSS3 and HTML5, so it is really only limited by your skills and knowledge. Many bloggers have showcased their content beautifully using one of hundreds of WordPress.com themes as a base and customizing it with the Custom design CSS upgrade.
The Custom CSS feature on WordPress.com now supports all of the new features of CSS3. This means that you can use gradients, animation, multiple backgrounds, @media queries, and many more new features in your custom CSS. — Custom CSS gets an upgrade
If you have CSS editing experience the WordPress.com custom design upgrade will allow you to stylize the appearance of themes you find here Appearance → Themes, including customizing fonts.
Custom Colors is designed to make it as simple as possible to update your blog’s color scheme with just a few clicks. Adding Custom Colors to your blog just got simpler than ever! Now you can change your entire color scheme with the single click of a button.
Adding color to your blog makes it stand out and gives your message impact—so wrap up your work in that perfect color choice! To try before you buy, go to your blog’s Appearance → Themes page and click “Customize” or open a live preview for a free theme and then click on the “Try Now” button. — Custom Colors Previews All Around
The WordPress.com custom design upgrade will not allow you to change the functionality, by editing the underlying template. It does not allow you to edit HTML markup, PHP code, or content. It does not allow you to remove footer links to the theme designer or to WordPress.com. Also note that CSS is theme specific, so you cannot use the CSS stylesheets from other themes with the themes at WordPress.com. For more information on what can and cannot be done check out the Custom design FAQs at this link.
A WordPress.com blog can either be structured as a page based website or its conventional post based structure can be retained. See > Using WordPress.com to Create a Website That’s why understanding the differences between posts and pages, the SEO implications of creating a page based structure, and knowing how to create and use custom menus are key to selecting a theme, and setting up your WordPress.com blog.
1. The main difference between a blog and website is the communication style. A website has a noticeboard communication style. A blog is a website designed for interactive communication. Collectively blogs create the blogosphere, while websites are like standalone islands.
2. It’s because blogs encourage conversation that businesses with websites are adding blogs, and sometimes forums and wikis to them for complaint handling, customer feedback purposes and for collaborative purposes.
3. Blogs feature dynamic content and position it front and center. The entries have date and time stamps, and blog entries are customarily displayed on the front page in reverse chronological order. Most most websites do not have dynamic content on their front pages. Many websites have static front pages. The information most websites provide is static, rarely updated, and the sites are often poorly maintained.
4. Blogs have RSS feeds, websites alone do not.
5. Usually but not always, blogs rank higher in Google as “freshness” is extremely important when it comes to content appearing in the SERPs.
WordPress.com vs WordPress.org Comparison
On one hand, the characteristic “blog” features like categories, tags, authors, dates, etc. cannot be removed from a free hosted WordPress.com blog, without purchasing an annually renewable custom design upgrade and doing the required CSS editing.
On the other, one can edit a WordPress.org theme free of charge. This comparison WordPress.com and WordPress.org: The Differences provides clarity.
