Inconsistencies at adsense techniques

You can target a similar KW, a one that is related to this one. If a KW have high competition then you may find long tail KWs to target.

But if you want to stay with this KW, then you will have to get some strong/trusted backlinks. Try to get backlinks from sites that SEs trust.

Can anybody answer to this question, please?
It is a key point to consider?

Not quite sure what you wanted to know, but here's what I was saying in order:

1. When deciding whether or not to attack a KWP, I'd look at the specific URL (page) strength first. In other words, while Widgets.com might be very strong, Widgets.com/products/category/this-is-my-page-here.html might not be. For the most part, you're trying to rank against a page (homepage or otherwise) and not the entire domain.

1A - Google looks at many different things when ranking. I find it best not to assume too much.

1B - Sometimes when you see big names you know of on page one (Amazon.com for instance), it's not because the homepage has huge "authority" in the SE world, rather, it's because sites under it have done a poor job at attacking the KWP. If you look, you'll see that most of these sites have the KWP in the url, title and on page for starters. Oddly enough, the world is still filled with a large majority of sites that would rather have "Welcome to my site" in the title.

1C - The point here is rather than getting instantly put off by any "name" in the SERPs, do your homework. Why are these sites there? If you can't come up with any conclusion (good backlinks, on-page SEO, etc), then possibly they are there because no one else is doing much right. And if you can see why they are there, then it's just a question of whether or not you can do better and if you want to put in the required effort.

2. I see a lot of people that misunderstand what "low competition keywords" really are. For the most part, many just look at search #s and stop there. Unfortunately, just looking at a KWP's result number competition doesn't give you the whole picture.

2A - Since your goal is probably to get on page 1 of Google for a KWP, you need to actually look and analyze page one results regardless of how "competitive" the KWP appears to be. In my last post, I was giving an example of a KWP that would be "all systems go" usually. However, upon further review--yea, it's footfall season--the first page for this KWP was very, very hard. Therefore, even though the KWP was a green light for competition results, it was a huge stop sign for page one glory.

3. In closing, I was just pointing out that you really need to experience these things on your own. Imagine if you put up a site and pop a page one result with Amazon, Wal-mart or whoever else sit there. Imagine if you get a #1 or #2 result? You won't be too scared again right? You'll also start to create that "feel" for KWP penetration.

Good luck!
