According to me these are the most important factors, because all websites are been made with a focus of selling something. Selling here includes services,income from Adv.,goods,etc. So, even if you are ranking high through PPC  it will only increase the bounce rate of your site. Because the only factor which works after a visitor enters your site is the content of the site. And if there are grammar / spelling mistake in your content, it will spoil the reputation of your site and end up with high bounce rate. But as an Internet Marketing Consultant if I would only concentrate on ranking I would say it hardly makes some difference.

Google just introduced a new webmaster tool in concept of Disavow Link. This tool will be needed only by those who where caught in link Spamming  i.e. if you find a notification called unnatural links on webmaster, you will have to work on it. Initially you need to remove all those low quality / Spam links pointing towards your site(Note: This includes all links that violate Google's Quality Guidelines) manually. But it's obvious that you won't be able to trace each and every link that violates Google's Term and stop it, but should at least stop as much as you can.Because that would help you in preventing your sites reputation being drained further.


If you are the guy who has already reached this stage, Now it's time to use the new tool.


As you visit the page:

1. Select the site you want to work on
2. Upload a simple .txt format file which contains the list of unwanted links.

The format should look like:

Marketing does not works the same each time. It mainly depends on the latest trend in the market. If your product is out of fashion/trend it's next to impossible to push the product in the market. But that won't be the scenario after a gap, say if you got struck with a out of fashion product in the market, then the first & foremost thing you have to do is to pack it properly & store in a good place. You might be thing I am joking but that's the truth. It will be very hard to push a product which has been out of fashion recently, But if you are actually talented  you could easily dump it after a gap when all you competitor will be busy finding the latest trend. This concept is not a sustain method of marketing but can be used at times. Market trend actually never changes at it's own but is been made to change by guys like us. As an entrepreneur i would say it's profitable for us if the trend changes frequently in the market, with accordance that you should understand the market & behave accordingly.  
Now let's look at an example of good marketing.
The video below is just an advertisement to join that guys site/subscribe for newsletters but look at the heading he has given "How to Increase Business with simple marketing Techniques & Strategies"
it's obvious that anyone would be attracted by such heading further listen to his speech, he  pressurizes some words like "exactly" which would increase your eagerness to know more. Such hidden qualities will help you out proving to be a better CMO (Chief Marketing Manager).

Ye! It's next to impossible to sustain in this competitive market without branding your company & product/services. Because today we don't find anything like monopoly kind of market. The market is open to everyone, Day's when customers where completely illiterate about the products has vanished. Today everyone knows everything with the help of Google,Bing,etc. So, the only option left with you as a seller/manufacturer is to maintain the best quality & price. But simply maintaining quality & price won't help you initially, this things will help you to sustain you customer in long run. But initially to attract the customer towards your product is the most tuff job for any company/firm. This needs many factors among which branding is one of the most important factor. Once you are successful representing yourself as a reputed brand, 50% of the job is done. Because a brand creates an impression & faith on you and your products in the market. Customers feel more safe choosing your product, because they think that anyone won't spoil the image of their brand for a single product. And this logic of customer is the main chaises to the companies. For example: Say if two companies are launching a new product in the market at same time with all other factors same, but one is a reputed brand say like SONY or NOKIA and the other is a new company not familiar in the market. Even if the quality of the new company is better than this well known brands, it's obvious that anyone will go for the well known brand initially.
