With the choice of 100s of CPA Networks how do you whittle them down to the best quality and value? How should you know which to sign up for and why not just join them all?

1. Look for a trusted network -  CPA networks come and go, some stay for longer than others so look for a well established network with good positive feedback in Google. There are many forums for discussing CPA networks and its easy to search Google for content related to the network you are researching.
2. Look for a CPA network that has experience in your niche - different networks have different areas of expertise, look for one that either has experience in your niche or in your wider sector. This will help match more relevant adverts to your content helping your conversion rates.
3. Look for networks without automatic enrolment - networks that let anyone in are bad for the overall quality of sites. Networks that have strict guidelines are more likely to have better quality merchants and publishers.
4. Look for networks with a lot of offers - look for a network with at least 100 offers so that you have the choice and flexibility in choosing advertising for your website.
5. Look for networks with high payout percentage - it goes without saying that you want to get as much as possible from the adverts you run on your site so shop around until you find the best rates.
6. Look for networks with good transparency on tracking - you want to make sure that every offer that goes through your site is tracked.

With the hayfever season quickly approaching its that time in the year where my throat won't stop itching, nose won't stop running and eyes won't stop itching. I've tried a lot of things over the years from various antihistamines, sprays and local honey.

What I found worked well last year was a good air purifiers in the house and I'm now looking for one in the office. There are many things to consider when looking for an air purifiers, here are some of the most important:

• HEPA Air Filter - these trap upto 99.97% of polutants and are the most effective types of filter.
• Carbon Air Filter - these are the most absorbant types of air filter and are very effective at removing nasty smells and chemicals from the air.
• Air Ironizer - by releasing negative ions, particles in the air are more likely to clump together be filtered out.
• Lasting Filters - many air purifiers require you to change filters every few months, when buying check how often you need to change filters and the cost involved.
• Noise - many air filters include fans which can cause noise, make sure you check the noise rating when buying.
• Electric Consumption - air purifiers can be expensive to run so check the energy rating when buying.

A few photos I've taken out and about this week in Shrewsbury.

Build IT International build schools, health facilities and housing; employing local materials and sustainable technologies throughout sub Saharan Africa and are based in Shrewsbury Shropshire.

After a period of fantastic success, completing their latest projects , Director, Andrew Jowett knew they needed to raise their profile to take the charity to the next phase. "I've always known how the Internet could be used as a powerful social tool, but I've been too focused on the work at hand to spend the time on it required" explained Andrew. For this reason he employed local web designers, The Web Orchard to create a complete online personality for the charity. "We're very pleased with our new website but it's been the extra attention to detail, promoting our activities on Facebook and Twitter that really gets our message out there. We can easily communicate with massive audience." said Andrew, adding "Please follow us on Twitter @build_it_int

Their previous website had lasted for a number of years however the short comings were becoming increasingly clear in an era defined by social interaction and interactive media. The Web Orchard's Chief Web Architect Pete White said “Build It International have some outstanding past and present projects and with their archive of content, imagery and videos we wanted to showcase as much as possible whilst maintaining an easy to use, informative website. Build It have a lot to say and we didn't want to overwhelm a visitor, so there's some neat design gone into their website to allow the reader to view the information at their pace.”

Since its launch in October the website has seen a 50% increase in traffic and has helped generate a greater awareness of the charity and the work it does. Charity Director Andrew Jowett added “We’ve been thrilled by the work The Web Orchard have completed for us, their attention to detail and service has been excellent”.
