I noticed some online gambling directories with pr=4 for example. But if I check a specific page such as dir/hobby/gambling/poker strategy/, pr=0.
The question is if I get listed, I get a back link, but what is the pr? it is zero or small like 1 as it is coming from an internal page and not the main page.
If so it does not seem to help much for my pr, does it?
Alternatively is there a list of free gambling directories where it is recommended to get listed?
Not only online gambling directories, but general directories will not have PR for internal categories in most directories. These internal category pages are cached and due to that all listing in category is of same theme so they becomes reputed theme based pages and links or listing in these categories helps you in keyword rankings.
If you are looking directory listing for PR, it may help but not that much because directory listing helps in keyword rankings.
Each directory link is good if you are getting from theme based categories, you get link with different title or anchor text, links from relevant theme or topic categories, links come from both old trusted directories as well as new sites (better mix). Directory links are permanent.
First, PR is NOT what it used to be and not neear as important as search engine ranking in the serps (results pages)...and PR and serps are not the same thing.
If you are linking specifically to boost your pr, or deciding whether to take a link from someone based solely on their pr, then you are not linking in the best way you can.
I would rather have 10 solid links from quality sites, that match the theme (to and from each page) with the correct anchor text from pr0 or pr1 pages than to have 50 or 60 links from pages off-topic with the wrong anchor text from any old site with pr3 or pr4.
In the end, the better chosen links with proper text from proper pages will do more in the serps then the hap-hazzard ones.
From you post, i have idea that you are more concerned with PR. It will help in building your PR but if you are only concerned with PR, you need to get links from high PR sites.
But as i have seen, that low PR sites ranks well as compared to high PR sites due to quality contents, links from all sources and well optimized.
Here when i say links from all sources, i mean links from casino sites (theme based as explained by Rick) and links which include custom link acquisition, blog review links, discussion forum links, article links, press release links, quality directory listings, hosting marketing pages, social media links, links by link baiting
Some directories can bring also traffic to your site, if they have good SERP for relevant keywords.
Be careful: inserting links in directories that use the rel="nofollow" attribute is completely useless.
You should try casino/poker/gambling niche directories Before submiting your website you must check the following points:
.Static Text Links
.Age of Web Site
.Major Search Engine Inclusion
.Alex Ranking and Google PageRank
.Quality of Websites Listed
.Directory Ranking
.Number of Outbound Links
.Back Link and its Quality Check
.Payment Option Annual or Permanent
.Major Directory(DMOZ, Yahoo, Ezilon, Botw, Joeant, more...) Inclusion
So if I list there in the "theme" poker, I will have a back link from pr=0, so it will not count in my pr?? this is the question.
A link is a link, It will still count as long as the page is cached/indexed by Google though the weight is not that much to boost your PR to a remarkable degree.
Most directories will only help you increase PR and SERPs. However, there are some niche directories that get search engine traffic and some of those clicks make it back to you. Take a look at the directories in your niche then try a google search for some of the long tail terms on their page and see if they come up.
