This is just an excellent component, but where most people would rate it because it's well programmed and the support is fantastic, I'd like to add another perspective:

We've been running a "yellow pages"-style website since 2001, where people in the wedding business of Denmark advertize.

In the recent crisis, it's never been harder to make the shops and vendors pay for advertizing.

Having this alternative (link exchange) it's really a win/win/win situation because THEY get a little free advertizing and WE get a link, ie. better rankings in Google.

But wait....did I say win/win/WIN? Where's the 3rd win? It's here:

Getting people to pay for online advertizing is often hard because no matter what price you offer, people often expect it to be eithe free or very cheap, compared to old media types.

Paying for online advertizing often becomes a barrier for getting new clients, and when we can now offer them a free link-exchange, this payment barrier is gone and when they're on our site, we can THEN start selling them our real advertizing. Then the barrier is gone :)

I bought JV-Contentlinks (and also JV-relatives) for our sites and our sites now have more visitors AND lower bouncerates.

We have quite a large website and because we have, like, "hundreds" of articles with each of our important keywords, Googlebot can easily pick the wrong one as your "best".

This is often referred to as "keyword cannibalism".

JV-contentlinks makes it very easy for you to make the "link juice" flow to the right article, which Google can then easily mark as THE important one.

Also, the support is some of the best I've seen - Vinjay is super!

I bought JV-relatives (and also JV-contentlinks) for our sites and since then, we've had great results in search engine ranking and our bounce rate has gone donw.

Why?

Because these two components makes it visibly very easy for the users to read other parts of the site.

When you're reading one article, JV-relatives shows the users, like, 10 other exciting articles and many people do read on.

This makes your usres happier, Google-bot sees your bouncerate is going down and thus gives you better rankings because you have proved to Google, that your site has great content (if not, the bouncerater would be higher)!

The support for this component is fantastic - Vinjay does a GREAT job and responds in a polite and nice way!
I really support the JV-components and plugins!

A little more "eyecandy" would make this the best PM solution for Joomla.

The icons / smileys looks like 1995 ;)

How can you NOT love a module like Meta Mod?

At our site, we're quite "agressive" towards showing people banners about registering at our site...... now, with this module, we can stop showing the banners, once they log in!

Super cool!

This is a great component - I replaced Phil Taylors KnowledgeBase with this one.

It just beats other (even very expensive) commercial components easily!

Until now, our huge weddingplanning portal has been free to use.

In the future, we'd like to be able to charge the users for using the site and we'd like to do this in smaller steps.

jContentSub allows us to do this, as it can handle free subscriptions very good. This way, we can "train" or "learn" the users that they need to have subscription and when they're used to this, we can start charging. Smaller steps rather than one giant leap :)

Being very focused on SEO, I found a huge "bug" with jContSub though, as it not only blocks non-subscribed users from seing the site content. It also blocked Google etc. which would mean that 90% of the site would be unavailable for indexing.

I took contact to the programmer, Sergey, and he liked my idea, so he wrote a new version that still lets the search engines index the site while the non reg. users cannot see it.

This is an AWESOME enhancement of the component and I see no reason why we shouldn't use it on our site!

Also, I think it has more flexible payment options than other similar products. Yes, you can charge by Paypal etc. like the other subscriptioncomponents, but jContSub also works regardless of any online payment as you can have it use standard email. This is great, as less than 5% of our users in Denmark have Paypal or similar. We use a special danish creditcard and this way, we can just mail the users on how and where to pay!
