How do I choose the best keyword by using different tools?

Hi gurus, I did a research of these two phrases,if possible,please take your time to help me to analysis them, I did the following job:

Organic searches on Google:
1)weed control fabric, (there're 1,500,000 results)
2)bulk bags, (2,830,000 results)

SERPs on 1st page of 1):Quite of few are HOMEPAGES, most are product webpages,meanwhile,most of them are competitors of our company.

Of 2):Are mostly INNER PAGES B2C or big e-commerce sites,such as Amazon, Walmart, and other B2C sites, and youbube, landscaping.about.com as well.

Analyzed with Google keyword planner:

1) Monthly searches:4400, competition:high(1.0), bid price:RMB4.01
2) Monthly searches:2400, competition:high(0.96), bid price:RMB30.29

Used Moz keyword tool to analysis:
1) Volume:501-850, Difficulty:34,
2) Volume:851-1000, Difficulty:1

As some people think Google keyword planner is mainly useful to Google Adwards,this tool is not very available to SEO analysis.However,I think it has great reference value.

Let's see the results of MOZ tool,obviously I should choose 2) because it is high volume and low difficulty,but how can I get the conversion of them? Maybe 1) has high conversion because of its high competition, I am very very confused to this problem.

On the other hand, how to analysis the competitions with a combination of the above three ways?
Or, just use the MOZ keyword tool to do research because it is accurate enough?

Could anyone help me?
Thanks in advance!

 

Sorry made a big mistake, the beginning should be:
Organic searches on Google:
1)weed control fabric, (there're 1,500,000 results)
2)bulk bags, (2,830,000 results)

SERPs on 1st page of 1):Are mostly INNER PAGES B2C or big e-commerce sites,such as Amazon, Walmart, and other B2C sites, and youbube, landscaping.about.com as well.
Of 2):Quite of few are HOMEPAGES, most are product webpages,meanwhile,most of them are competitors of our company.

 

results are deceiving which google shows below
but actual result is 420000 for bulk bugs and weed control fabric is 99400.

Google keyword planner competition is not for you. its an Ad competition.

As per moz result competition below 30 is best. you have to look top 10 pages of SERP, less than 3 eCommerce, low PA, DA less than 30. the most important thing is to analyze back links. heavy back links kill your keyword to rank. low back links have opportunity to rank your keyword.

If you have Long tail Pro software then you should try your keyword with Long tail pro software.

 

can you help me out which location you are targeting ??

 

This make sense guys, I believe you that makes your result different from each other.
