The quick answer is yes, they are nofollow and no, google will not penalize you for using InLinkz.

Now the complete answer:

we comply to google webmaster guidelines, and especially the “link schemes” part (https://support.google.com/webmasters/answer/66356) which may be relevant for link parties.

Regarding people that link to parties, outgoing links from the InLinkz widgets, are nofollow and there is not even an option to have them otherwise. This is done to not characterize the links as black hat link building and be penalized by Google.

Moreover, all links in the InLinkz linkup tool, are directed to one specific page on InLinkz, which is invisible to the google search engine, through robots.txt so as not to be considered an attempt to pass page rank (this is what pisses google off)

Even though links go through inlinkz, we use the so called 301 redirect. What that does, is that it keeps the referrer (that is you) and it passes it forward to the target site. It still does not pass any pagerank of course. This is done so your readers can see on their statistics software, that the click has originated from you.

So, as an InLinkz host, you will not pass pagerank to your readers (and you shouldn’t as google would get pissed off) but you still register as your readers’ click source. (which makes them link up again in the future as they can see where the extra traffic comes from)

On the other hand, an InLinkz linkup can help you build your incoming links by requiring backlinks to your website. Through the required backlinks feature of InLinkz, you can require from your readers to add a direct html link that points from their site to yours, which as you already know is most beneficial to your exposure. Keep in mind that you need to provide a button or link to your readers yourself if you want this to be done properly. In any other case, each reader will be free to construct whatever she wants (which is not always the best for you). If you are a high-ranked blog, you would probably want to provide them with a button with a nofollow attribute set to its <a> tag.

As a rule of thumb, do require a backlink so your entrants’ readers can also visit your blog but provide yourself a button or link for them to put in their blogs, that has the rel=nofollow attribute set so you stay google-compliant.

And of course the usual benefits apply: increased traffic and social exposure which creates even more traffic and loyal readers.

Of course, we are constantly watching google’s guidelines, which are indeed targeted on a better web, and do our best to make the inlinkz widgets support this by connecting people and sharing talent, while complying to those guidelines so our users can benefit as much as possible from using them.

Script codes leading to inlinkz pages (e.g. the wordpress.com code) are also set with a nofollow attribute.

See the code breakdown of an inlinkz link (the nofollow attribute is noted)

nofollow attribute set to all InLinkz links

For a snippet of code to let others backlink to you, a simple example could be this:

(lets assume your site is http://www.example.com and your blog name is “Jane’s chicken fillets”)

<a href="http://www.example.com" rel="nofollow">I added my link over to <b>Jane's chicken fillets</b> </a>

In general, you can use whatever you use up to now, just add the rel=”nofollow” attribute inside the <a> tag.
