Content, Content and More Content!

If you want to get a good ranking in Google, you should need some quality high pr backlinks. In the past the Google's algorithm is only checked the number of backlinks to your content/sites, but now it is changed and it checks only the quality of the backlinks. So if you want to get a good ranking you should need to build some quality backlinks +1 and above pageranks. Then you will get a good ranking in Google. You can build quality backlinks by submitting your site to high pr directories, web2.0 sites, socialbookmarks etc.
You can post any number of posts/articles. And always posts frequently to get more readers and popularity for your sites/contents.

It depends on the competition for the keyword which you are targeting.. Google likes websites which are updated.. More the content the better, which does not mean that you post link 10 articles in one day.. Post something like one article every 3 days along with some quality backlinks..

There is no any particular character limit to develop content to promote your site. But the thing is that build such content that can be meaningful and useful for visitors and not be just for the site or product promotion.
And there is no specific limit to how many articles or blogs, but again the thing is whatever you provide, offer the best only. Suppose if you have 10articles but nothing meaningful, there is no any value of those articles to get results. But if you have one article and that is effective then it will sure give results to you.

There is not enough content, only quality content. An article of 100 words can be better than one of 500 words, if it's better SEO optimized.
Since you are going to write reviews, you should also be honest, so that people who read your reviews will not be disappointed for trusting you.

Backlinks are more important than contents. Yes definately you need a minimum amount of content to rank high. But backlinks play vital role in this game show.

It's all about the juice and content does not create juice, backlinks do. What I noticed is that 100% copied content ranks just as well, it only has a bit of a slower start. In fact a 100% copied sales letter on one of my site ranks better then all the other articles that I wrote myself.

Perhaps cause that sales letter is of higher quality then what I write myself, I'm not a native English and I didn't bother about LSI, so you can easily say that quality content ranks better, whether it's original or not.

If you only promote 1 product I would say you need only 1 page. You can build 2 supporting pages though and link back from them to the main post and then target all 3 pages with the same keywords, that way you can get multiple listings and thus more visitors.

Here are some rule of thumbs:

1. How many post/articles to write will depend on your niche and competition

2. Generally, the more articles/post you write (assuming they're of high quality and something that your users will value), the more likely you get picked up in rankings

Unfortunately there isn't a set amount of content required - ranking well involves numerous factors. If you bought a relevant, backlinked, aged domain in a niche with little competition, you could be ranking on the first page within an hour of posting your article.

Google isn't a particularly big fan of thin micro niche sites. That's not to say they're impossible to rank, but there are much easier ways to go about making your first dollar online.

Whilst I normally recommend people keep a tight control over their content, in this particular case it may be worth considering posting your review at somewhere like Squidoo, as the project will be very much a learning exercise anyway.

You will learn far more by getting started and making a few mistakes than you will by planning every last detail. There's no reason why you can't upload some content to Squidoo or Weebly today/tomorrow and set about promoting your review.

If all goes well, then great, you will be making a bit of money and well placed to start your own site. If things don't turn out as expected, then there will be valuable lessons to learn which will ensure that your next project is more likely to be successful.

Oh comeon HD node, it's much easier to rank a 100% EMD cause Google still gives a huge benefit to that, so that would be a MUCH better 1st project to get to learn the ropes.

Its depend what kind of work you are doing. If your are selling your product then you have to write more and more content about your product.

Exact Match Domain

So when you target the keyword: "payday loans" and you have the domain paydayloans.com then it's an EMD, which gives you a benefit when ranking.

Some people claim that partial EMD's also give a ranking benefit but I don't really believe in that, the only reason you get a benefit with a 100% EMD is so that company names rank easier for their "company name". So you can take advantage of that by putting your exact kw in the domainname (when it's available, all the best ones are taken obvious).

Write high quality articles that are a little longer. Also, using images and putting the correct tags will also give SEO benefits.

There is no limit whatsoever because everything depends on your writing skills and also your interests in the subject. For example, you can find shopping portals with just one single article written as a review on a specific product while another portal could contain a whole library of comments and reviews on the same package. The general rule of the thumb is that the more fresh, highly relevant and informative contents on your site, covering the main issues, the better outcomes will be gained.

You are the only person who knows what ranges of information are to be covered through written pieces and think of what materials will be the most useful for your web readers, temporarily forget about what search engines like because if net audience loves the contents on your site, Bingo. You have come to the accurate conclusion that nothing beats having valuable contents on sites because once they get combined with packs of links, increase in traffic and improvements in ranks will occur.
