- $link: news item link (item.link)
- $description: news item description (item.description)
- $date: the publication date (item.pubDate, item.date)
- $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>.

Sometimes, being a business owner can seem like a non-stop uphill climb. Of course, that's part of the fun, right? Still, if you'd like a little extra help getting to the summit, these technology tips should help.

1. Take It to the Cloud

The cloud is everywhere these days and for good reason. It makes life so much easier on everyone. As a business owner, you can store all kinds of documents on the cloud and rest assured they'll remain secure. You also don't have to worry that they'll be taxing your digital resources. It's also easy to grant permission to other parties, so you can share them with employees and customers from one central location. They can make changes without needing to hit ''reply all'' on an email.

No matter where you are, the cloud is available. Bring up an important document on your phone, tablet or computer from anywhere in the world.

2. Ditch Pricey PoS Solutions

Point of sale solutions have always been necessary for B2C companies that accept credit and debit cards. Unfortunately, they've also been rather expensive, traditionally. This can be a huge burden for small businesses trying their best to compete with larger organizations.

These days, though, solutions like Square make it possible to easily read a card and accept a payment, just like you used to do with PoS devices. Whether you own a food truck or are a babysitter, your overhead just got a lot lower without having to sacrifice any funds.

3. Rewards Programs Are Easy

You always want to be incentivizing your customers, but in the past, this usually meant clumsy and expensive reward programs. Well, not anymore. Loyalty programs like Perka, Belly and FiveStars make it extremely easy to turn every customer into a repeat buyer.

4. Accounting Has Never Been Easier

As a small business, hiring on a full-time accountant may not be realistic. However, if you don't have a background in accounting, trying to run the books on your own could become detrimental. It could even land you in legal trouble eventually.

That's why you should look into titles like Wave Accounting, Freshbooks and Shifthub. These are just three of a number of cloud-based platforms that will make your accounting needs something you can easily handle on your own.

This is just one example of how you can replace the need for an employee with software. Whether it's HR or customer service, chances are there is a program out there that can come to your aid.

5. Get Social

There is just no excuse to not be using social media as a small business owner. Never has it been easier to reach out and engage with your customers and do so in a meaningful way.

On top of that, as a small business owner, you can afford to be a bit creative and try new things to connect with the public. Feel free to show the personal side of your business and you may find that people repay you with revenue.

Being a small business owner is never easy, but that's also no reason to make things unnecessarily harder on yourself. With these technology tips, your business goals should be that much easier to obtain.

If you're already doing business online, then affiliate marketing can be a tremendous way to grow and develop an additional revenue stream. That's the reason why so many bloggers, for example, choose to participate in affiliate marketing programs.

There is, however, a common belief that making money through affiliate marketing is as simple as participating. This is not the case. In fact, going about affiliate marketing the wrong way can not only waste your time, it can also damage your own business' reputation.

RELATED: COULD AFFILIATE MARKETING WORK FOR ME?

Therefore, it's important that you avoid the mistakes that many new affiliate marketers make. What are those mistakes, exactly? That's what we'll be exploring.

1. Taking on Too Much

The idea of making money through your blog sounds tremendous! Obviously, the more relationships you enter into the better, right? Wrong.

When you're getting started with affiliate marketing, it's going to take some time to learn what works and what doesn't. Remember that you have a particular audience, and that you need to market in a way that appeals to them.

For this reason, try to focus on one or two relationships when you're starting out. Do what you can to meet with success in those relationships, and keep track of what strategies are working and what aren't. Once you've hammered those relationships out, seek out more, and then apply what you've learned.

2. Not Vetting

When you choose to become an affiliate for a business, what that business does is going to reflect upon you. If that business is doing something untoward - relentlessly spamming the customers that you send their direction, for example - then that will damage your reputation with your audience. Therefore, make sure you research any potential affiliate offer before you sign up. Make sure it's something legitimate, and not something that's going to leave the members of your audience with bad tastes in their mouths.

3. Only Selling

Making money through affiliate marketing requires that you sell products or services for the businesses that you enter into relationships with. However, that does not mean that you should be ''selling'' to your audience. As already emphasized, remember your audience. Likely, they do not expect (or want) you to sell them products; they want you to inform and to help them.

RELATED: AFFILIATE MARKETING OPPORTUNITY: SFI MARKETING GROUP

When you're crafting content that's aimed at driving traffic toward an offer, don't try to sell the offer. Instead, explain the product or service behind the offer, and tell the story of how that product or service is going to help your readers. This will yield to a higher conversion rate, and it will also build the trust that your audience has in you.

You'll Get There

The above are, without a doubt, the three biggest mistakes that those new to affiliate marketing make. If you manage to avoid these mistakes, and to do what we've suggested, you should get your affiliate marketing sea legs beneath you. Just remember to keep learning and to keep your eyes on others who are having success. If you keep at it, affiliate marketing could become a significant revenue stream for you!
