What is the logarithmic scale used for domain authority?
-
I want to quantify how much better a score of 80 is compared to 60.
Or 60 compared to 30 etc....
What is the logarithm base?
Thanks,
Rik

It turns out to be a bit complicated, since DA/PA are based on a machine-learning algorithm. Dr. Matt Peters, our resident data scientist, answered a similar question here:

Canonical URLs all show trailing slash on main site pages - using Yoast SEO for Wordpress - how to correct
We are using Yoast for a number of our sites. We use naked domain as the canonical. I have noticed in the header tags that all our sites show the canonical URLs as having a trailing slash: Example: http;//foxspizzajc.com, when I look at the source code, it shows the canonical as http;//foxspizzajc.com/ Of course, it is much more likely that all sites that link to us will not use the trailing slash - so preferably we do not want that to be the canonical - among other reasons. Does this need to be fixed so the trailing slash is removed? I cannot see how to do this in Yoast SEO or in Permalinks structure for Wordpress. Sorry for my ignorance. Thanks for any help.

Is this wrong should this be a 301 redirect? There is no link juice to pass. Thanks

Automatically Check List of Sites For Links To Specific Domain
Hi all, Can anyone recommend a tool that will allow me to put in a list of about 200 domains that are then checked for a link back to a specific domain? I know I can do various link searches and use Google site: command on a site by site basis, but it would be much quicker if there was a tool that could take the list of domains I am expecting a link on and then find if that link exists and if so on what page etc. Hope this makes sense otherwise I have to spend a day doing it by hand - not fun! Thanks,

Comparing Domain Authority Scores
Since your scale (like PageRank) is a logarithmic scale, it makes it hard to judge the distance between 2 scores. Can you give me a rule of thumb. For PageRank, each jump is an exponential jump - so that a PR6 is perhaps 10 times stronger than a PR5. What is the log base that SEOMoz uses. Should I assume that a 60 is 10 times stronger than a 50? This is important when it comes to measuring progress because growth is going to get more difficult as you move up the scale and I need to communicate the distance between our current Authority score and our goal. Thank You!

In alt tag of a image can we use #hashtag or domain.com ? Is that good SEO or not allowed ?
Some of the Google Search shows a title has a hashtag of an article, which contain keyword and while tweeting them, the title which has a hashtag automatically very good used for getting traffic to the blog. And other one, can we use the hash tag inside the alt attribute ? Or our domain name with .com in it. Like Google.com or #Google ?

Page Authority is the same on every page of my site
I'm analyzing a site and the page authority is the exact same for every page in the site. How can this be since the page authority is supposed to be unique to each page?

Use of the tilde in URLs
I just signed up for SEOMoz and sent my site through the first crawl. I use the tilde in my rewritten URLs. This threw my entire site into the Notice section 301 (permanent redirect) since each page redirects to the exact URL with the ~, not the %7e. I find conflicting information on the web - you can use the tilde in more recent coding guidelines where you couldn't in the old. It would be a huge thing to change every page in my site to use an underscore instead of a tilde int he URL. If Google is like SEOMoz and is 301 redirecting every page on the site, then I'll do it, but is it just an SEOMoz thing? I ran my site through Firebug and and all my pages show the 200 response header, not the 301 redirect. Thanks for any help you can provide.
