Keyword Related Question

It depends on what is your product or services for.If all of your keywords are same related to your target business then I suggest go for the last keyword and make it a keyword riched domain. and others especially 1st keyword which can be your main keyword for your website and go for next.

If you mean low competition according to AdWords or the Google keyword tool, you should know that the competition on there refers to AdWords advertiser competition and has nothing to do with search engine competition.

Also if you plan on using AdSense to monetize, stick with high and medium competition keywords (according to Google keyword planner tool).

I am guessing that you did keyword research to register a new domain name then you should go with highest search because all keywords have low competition.

I want to use it for google adsense not for products.

Difficulty to say..

All keywords depends on various industry you are searching for, all types of industry specific keywords have high and low competition. it mainly depends on your website or niche on which you are working.

Well done, those keywords are quite nice IF you can rank for them.

They have low competition - ask yourself why? go check Google search results for each keyword in turn.

They could be 'useless' keywords that do not bring (m)any sales for Adwords advertisers, therefore they cut them from their campaigns, making for the low competition figures, you will see if there are any paying advertisers on the SERP page

Whatever it is could be quite new and everyone and his dog has not yet jumped on bandwagon. (or added those keywords to their campaigns because they are not yet aware of them)

If the sites at the top are big authority sites like MS, Adobe, .Gov etc don't waste your time, find less competitive words.

If the sites at top of Goog are weak e.g. unbranded blogs/affiliate sites or forum posts then you stand a very good chance of ranking, but to make certain check out the banklink profiles of the top 5 sites and see what you are up against.

Don't guess at the links just because the the URL might be crappy, CHECK, because a site might be years old and have very strong inbound links.

If using Adsense then you will want as much traffic to your site as possible with any keywords related to your niche that you can rank for, but make sure you link those pages to your pages with the high competition (expensive) keywords on them.

All keywords depends on various industry you are searching for,
Ideally you want High Competition keywords for AdSense because you know advertisers are bidding and your site will display relevant ads.

In your case , I think using a keyword which is searched more often will be good. It will also brings traffic to the site. But decide carefully that you should use the same keyword to increase your rank as well.

It should be a dependable keyword.

I don't have any idea about this. If someone answer for this it will be useful for me too.
