- $category: the article category (item.category)
Global FORMAT setting

The header and format parameters might also use variables rendering the dc, image and content namespace information. Note, that only bits of interest have been implemented so far and those namespaces might not be implemented fully yet.

Rendering the dc namespace

The following variables are extracting the dc namespace info, that could be used in header and format. Nnote, that some of the variables are already used above. This is done by purpose to use different feeds with the same formating parameters. If there's a conflict the non-dc tags have higher precedence, i.e. a <title> content </title> is prefered over <dc:title> content </dc:title> .

  • $title: channel/article title (dc:title)
  • $creator: channel creator (dc:creator)
  • $subject: subject text; this will also add an image according to the subject hash list, see above (dc:subject)
  • $description: ... (dc:description)
  • $publisher: the channel/article publisher (dc:publisher)
  • $contributor: ... (dc:contributor)
  • $date: ... (dc:date)
  • $type: ... (dc:type)
  • $format: ... (dc:format)
  • $identifier: ... (dc:identifier)
  • $source: ... (dc:source)
  • $language: ... (dc:language)
  • $relation: ... (dc:relation)
  • $coverage: ... (dc: coverage)
  • $rights: ... (dc: rights)

Rendering the image namespace

An image:item is converted into an <img> tag using the following mappings:

  • src: image url (rdf:about attribute of the image.item tag)
  • alt: image title (title)
  • width: image width (image:width)
  • height: image height image:height)

Rendering the content namespace

The variable $content is refering to the <content:encoding> content </content:encoding>.

According to Albert Scaglione, founder and CEO of his family business Park West Gallery, business success depends on successfully marketing your products and services1. ''While selling your products is one thing, marketing includes all the components of creating and growing a customer base - and that includes advertising,'' says Scaglione.

If your business is already advertising on Facebook and not seeing results, you may not be paying attention to certain crucial tips and tricks. Consider the following to improve your Facebook advertising ROI:

Take advantage of the newsfeed. Did you know that 60% of all users visit Facebook from their phones or tablets? When placing your ad, it's important to take advantage of the highly visible newsfeed to ensure your content is seen front and center. Notably, using the right-hand column for ad placement doesn't offer as much visibility on the Desktop, and it simply doesn't exist on mobile, so for many businesses, it may not be worth it to place ads there.

Use the Power Editor feature. The Power Editor isn't a Facebook-specific feature; rather, it's a Chrome plugin that will help you manage and edit your ads. When you open your Power Editor, you'll find a feature called ''Placements,'' which will allow you to take any ad you've created and choose where you want it to show up, whether on users' Desktop or Mobile News Feeds - or both.

Create a custom audience. Facebook allows you to create an audience consisting of those who have already visited your site or from your email list. In this way, you can re-market to these people to drive your message home even further. Simply by placing a Facebook-generated pixel on your website, you'll begin automatically adding visitors to your site to your target audience.

Use optimized CPM. One way to make the most of your investment in Facebook ads is to let Facebook decide how much to charge for CPM. An incredibly well optimized system, Facebook can take your goals and adjust ad space bidding, allowing you to maximize your ROI. Marketers across the board believe Facebook does an excellent job of deciding on price for CPM. To allow Facebook to use optimized CPM, choose Use Default Bids in the section for optimization and pricing.

Include a CTA. The CTA on your ad is actually the first thing users will see - it's the title text. Make sure you urge readers to take action by clicking on your ad by keeping it short and to the point.

In today’s digital age, it’s easy to create a logo with all the bells and whistles. You may be envisioning a multi-color logo with depth and visual interest. Before you pull out all of the stops designing a complex image, consider how well that design translates into different media. In logo design, adaptability is key. Does your logo look good in black and white, or is its impact completely dependent on color? For most businesses, printed materials are a big part of their marketing campaigns. Although you may invest in a few high-dollar projects like a multi-color brochure or a media kit, most of your printed materials are likely to be more budget-friendly. Black and white printing is substantially cheaper than color printing. Beyond cost, you need a versatile logo that works for different purposes. For a glossy brochure, color is great. Letterhead and business cards are better suited to a black logo that creates a classic, sophisticated impression. There are additional considerations for online display. Imagine your brand new logo splashed across your website. Now imagine it on a big desktop monitor and then on the small screen of a mobile phone. Does it have the same impact? When creating a logo, you want it to be bold and distinguishable regardless of the size or the color.

See this infographic “The Recipe for a Perfect Logo” by Company Folders to learn more tips for good logo design.

Not everybody knows about Hollymatic's role in the history of American fast food, either. The company was founded in 1937 by Harry Holly, a laid-off ironworker who opened a tiny hamburger stand in the Chicago area during the Depression and then invented a machine to make more uniform patties in a shorter period of time. In the early days of the fast food industry, Holly's patty press could be found at McDonald's, Burger King and Wendy's restaurants.

''I don't think they ever gave credit to the guy,'' says Jim Azzar, the owner of Hollymatic since 1988 and Bauer's father-in-law. ''He was the inventor of the mass-produced fast food hamburger.''

That Holly's contributions went unappreciated is a result of both far-reaching changes in the fast food industry and turmoil at Hollymatic, which suffered financial losses and management upheaval that ousted the founder from his own company. Azzar, who runs a vertically integrated group of businesses related to meat processing, has fashioned Hollymatic into a niche player that caters to small and mid-sized restaurants, butcher shops and grocery stores. Where the company once supplied McDonald's and Burger King with patty machines, its equipment now helps make alternatives to Big Macs and Whoppers.
