John is right. In fact, these tools can often confuse people. Some of the metrics seem to be gee-whiz more than anything of value. Any online site like Open Site Explorer seriously lags behind and while this one is one of the very best, the reality is that the entire pool of online sites of this type are poor. The plain truth is, no one knows your link profile better than Google. So poke around and enjoy, but do not take it too seriously. The good news is, all the sites seem to lag about the same. For what it is worth.
In fact, the most accurate online tool I have found to date, is SEMRush. Any of these sites lag and can only estimate metrics, and SEMRush is no different, it is at least a valuable tool even when wrong. It is the only one I look at and would give my hard-earned money to.
As far as internal verses outbound external versus inbound backlinks, there is no ratio. It does not apply. If you are talking about performance, who you link to is important, but there is no rule of thumb on how many. Just make sure you link to quality sites and pages. If you are talking about inbound backlinks, then it does not require too many high quality inbound backlinks to set your site on fire. Even a moderate number of links from moderate quality sites can really speed things up for you. It really does not take much.
To Sum Up:
- Make sure your site is as good as you can make it (at least right
- Make sure you are cultivating the right users: Higher quality, higher
functioning. (for organic links)
- Make sure your site has content people want to link to. Be compelling
and of high value. (for organic links)
- Restrict scraper bots as much as you can. (reduce garbage links)
- Cultivate backlinks on your own. Be aggressive in your research and
gentle in your approach.
- Forget your competition and just make sure you are doing everything
I found that if I focused on my competition, I am not focusing on what I need to do. It is like looking into the rear-view mirror. I am paying attention to someone else's work and not mine. I am not looking forward. In fact, who is to say their SEO knows what they are doing? I found that I am a far better SEO now that I stopped looking and fretting and focused on my work. I am beating some of the big boys because of it.
