What's a good service to use for visitor referrals, i.e, a contest-system that gets visitors to your site in exchange for "entries".

I don't know any plugins with that specific feature, but I did want to mention this after reading your description. You can target specific pages/posts with CSS, so you can limit text wrap to your about page. You just need to know the page ID. WordPress includes a page specific class in the body tag. It looks like this page-id-123. 123 would be your page ID. See screenshot - http://i.imgur.com/zFldy2T.png So you can simply do something like this: .page-id-123 .slideshow-class { ... } This will limit your CSS changes to the slideshow on this particular page.

Not totally clear on what you are asking, but if the questions is; does giving out a referral code to an existing user in hopes that they would refer another work? My experience (largely in B2B software) is not all that well, at least not without some sort of incentive. Even if your user is super satisfied with the product/service you are providing, simply giving them a code to give another person doesn't necessarily drive them to make the handoff. Now, two things. First, if you either incentivize the existing user with say a discount on his next bill or a free goodie, then he'll be more likely to do it... Even better, if you do that, plus give the referred user some kind of benefit, like a discount on his first bill, free trial or other goody, then it can work rather well. Second, all that said, know that referrals in general are gold. You should test and do whatever you can to get referrals. Generally @Leads360 we found that providing really high quality customer service (more so than even the best product) lead to referrals. To that point, our sales people worked in tandem with customer service in this way. Whenever a CS person realized they gave a great customer experience they would let the sales person know and they would then reach out to that customer while still warm from the nice touch and simply ASK for a referral. I was always surprised when we could get referrals simply by asking. I like to stick with 1 referral at a time, just ask for 1 person to be email connected with, don't overwhelm them with the statement "hey, can you refer your friends and colleagues to us", be specific. Something like "I see on LinkedIn you're connected with John B from ACME corp, I'd really like to speak with him about our product, would be willing to make an introduction for me".

There is a lot of points in your question which unless someone has the exact same setup as you - I don't think you will get the answers you are looking for. I believe you should limit it by asking yourself: What is the ONE thing the MLM plugin I am looking for can do so that it achieves the maximum amount of result to my business by using it? IMHO - it would be the ability to set commissions for the products you sell and award commissions to those affiliates that actually earn you sales. All other features, while nice, are ancillary features that from the perspective of the affiliate - don't really need in order to be successful. In that regard - I would suggest https://affiliatewp.com/. When it comes to running affiliate programs on WP sites, it wins out as the best in my experience. Hope this helps! Glad to assist any further if you need help.

Take the # of hours it takes you to do it and charge $50/hour. That's the price. Eventually you can charge $100/hour but that will require a bigger customer. If the customer is small < $1M in gross sales per year - charge $50/hour If the customer id medium < $1-5M / sales - charge $75 Over $5M - charge $100 The challenge you'll face is clearly defining the expectations and handoff so that you're not stuck doing stuff that you can charge for and always getting interrupted from past customers.

Great Question! As I'm sure many other SEO's here have mentioned.. you should absolutely be leveraging the sub-folder as opposed to the sub-domain as Google and Bing associate sub domains as separate entities with their own value metrics outside of the primary root. The only real time I would recommend a sub-domain over a sub-directory would be due to platform restrictions (Shopify, Wix, etc) where you don't have access to build an infrastructure to support nested content from multiple hosts. Definitely worth chatting about, however you shouldn't have any problems using the sub folder with any other host you'd like.
