- Check outbound links for shadiness - Check inbound links for shadiness - Check entire site for references to non-relevant topics such as SEO and other bad neighborhoods - If they're engaging in direct commmerce in links, walk.
There are other factors related to whether it's a legit site or not. But if it's a legit site then yes, absolutely, go for it. The legit site test has always been my go-to metric. PR hasn't had an impact on rankings for me, at least not nearly as much as the metrics of legit.
As long as the other metrics line up then PR N/A doesn't matter. PR N/A can result from a 301. If you see that and need reassurance then run Xenu Link Sleuth on it to check for redirects.
If the site is less than a year old then it could be another story. Toolbar PR data hasn't been updated since February 2013. So what you're looking at is probably a snapshot of Toolbar PR from January 2013.
As long as the metrics of legit line up then you're good. Especially now, post-Penguin, the metric of legit matters more than ever.
I want to improve the trust and authority for my site
Then ignore PR and focus on the site's editorial slant with regard to its 'partners' (as MB said) and your gut feeling as far as the quality of the site goes.
For my sins, I gather lots of different metrics, but the only thing that would put me off partnering with a website is if their pages aren't indexed by Google.
Try assessing partner websites based purely on your impressions of the site as a potential knowledge or service seeker. I've done this recently and have then checked various metrics with the tools I subscribe to. I've found that the tools do tend to reflect an HONEST assessment of a site's quality, rather than how easy your outreach or pitch might be. Good sites, with good metrics, tend to look good from the outset. And if they're not rewarded by Google (or other) metrics now, they probably will be soon, and if you lock yourself in as a contributor or partner now then you will benefit long term by being in at ground level.
Long story short - go with your assessment of their INTENTION with regard to Google's stated aims re: quality. I don't think you could go far wrong.
PR has been broke for six months and Google may not fix it. A better gauge of quality is by looking at the page where you might get a link from and judge it on its quality and relevancy. No toolbar will tell you what your own eyes will!
Ever take a look at the code of some of these sites? It's not unusual to find a mismanaged WP SEO pack, with a noindex, nofollow set on the home page. That's an opportunity to be a hero AND get your link. But you wouldn't know it unless you looked at the source code.
In addition to good points raised by MB, 2 essential metrics I look for are -
1. Randomly checking pages for content to see if the target site ranks first for its own content. Takes care of a lot of potential issues. 2. See the search traffic metrics from one of the well known tools, to understand how much organic traffic the site is receiving from Google.
- Real PR updates daily at Google, don't go by toolbar PR as it is worthless. - Pages don't remain PR0 forever unless they are of poor quality or impossible to find on a site
So yes, don't be afraid of a PR0 while getting links if you see no sign of spam or blackhat tactics. Be weary if you see a lot of outgoing links to unrelated sites on that or other pages within that domain.
I agree with the above comments about the target site having bad backlink profile or linking to bad places, but would also add another caveat. What kind of traffic does the site receive? How many referrals do you think you will get? If the answers are very few and 0 then I would skip it.
I don't suggest getting links from sites just to rank a little better. You will get burned at some point. Look for links from sites that will refer traffic or add to your site's credibility/brand awareness. Doesn't matter if it's a PR10 or 0. Stick to that basic premise and you will sleep better at night and perform better in the long run.
If website has sufficient amount of links, good overall health, but have PR 0 on home page, it is likely that site is suffering from PR penalty. I remember the days when Google massively reduced PR's of sites which were selling links, I could see statcounter.com which was PR10 for years drop down to PR3, their PR was resumed once they put nofollow tag on outgoing links. Similar cases were seen on numerous other sites.
Toolbar PageRank is a tease; it doesn't tell you how valuable a website is. Look at the level of engagement of the website: amount of social shares, quality of contents, readers' comments (if the site has a blog) and the amount of web mentions. And of course, traffic (Alexa can give you a hint).
@mrengine - The pipeline might be broken, but one of my websites was recently penalized and dropped from PR1 to PR0. What's broken, then? Lately I take Google's statements with a grain of salt.
If it checked out by the many ways already suggested it's likely a good general link. I wouldn't persue tons of them but sprinkling a few of them amongst your regular link acquisition can make a more natural feel for your backlinks.
If the PR0 link came from a site that checked out by the many ways already suggested AND was in the niche of your site I would grab it without a second thought.
@Jon12345 If you want to develop links from 0 PR websites then you have to do lots of research on that. These are penalized or not and, whats domain age, website is translatable or not, analyse inbound and outbound links, How many outgoing links from link page everything. After that try to create link. All these criteria applicable for all kind of resources, not only for 0 PR.
And last if you will try to create links from high pr websites and apply all the criteria which i told you that it would be amazing.
So i will suggest you try get link from high pr websites.
