Metrics to look at before getting a link from - DA or PA or Spam Score?

[abhirupb]

If you want to know about a site then you have to check all of the metrics that you can find. All of these will generate a pretty decent idea about the site.

But choosing a site for links isn't that simple. You will have to check the content of the site by yourself. Or, get it done by anyone who knows about that field. Are real people looking for the content? Are they interested in? It's not always about the search engines. A site may not look like much now but it can have a potential in the future. If people like it then sure, you can proceed.
