What the most effective marketing tool on internet?

There is no most effective marketing tool on the internet.
I can answer your question properly if you can specify the type of business you work for or own, as well as abit of your target audience.
Then this question could be answered.
But as a start, I guess the below are effective (Unordered): 1.
Email Marketing 2.
Social Media 3.
SEO/SEM

LinkedIn Facebook Twitter YouTube

Digital/Online Marketing is a full spectrum, that compliments each other.
Yet you should focus on Search Engine Optimization (SEO) + Social Media, because both are Organic.
80% of the people on the internet Search for something, if you could optimize your online presence and generate useful content, you would increase the visits of relevant and interested prospects.
Once you capture the interest, you should start working these leads down the funnel, by engaging them on your various Social Media platforms, and offering them timely and individually customized offers.
I hope that helps, Farouk Achoui Digital Communication Strategist

I would say Email Marketing: The thing I like the most about e-mail marketing is that the list is yours.
A Twitter and Facebook following is very good also, but what happens when/if they die out like Myspace.
E-mail will always be there and you won’t lose the list.
That’s what I like about it the most.
And most importantly, the e-mail list should be targeted and quality!

For me, Its Social Media Platform where its just not only for the effective marketing tool but great in terms of Social Engagement of yourself or your business website on major Platforms like Facebook, Twitter and LinkedIn as the most prior based Effective Social Media Platforms.
You can not just only expand your connections (Followers) in these platforms but ofcourse a great way to analyze deeply and to work perfectly in terms of internet marketing.
Lets see some of the ways how to do internet marketing by using these platforms: a)Twitter: A best place for Micro Blogging where you can not only just add followers but a best way to do Internet Marketing of your products/services/business through Keyword Oriented Based Press Release.
(Make Sure not to add "#" symbol in your tweets which you think can be best in high ranked searchable keywords) b)Facebook: Best for business promotion through business pages, Communities, Groups and events creations.
c)LinkedIn: Again I found LinkedIn as the best place for Communities, Ideas Sharing through profile creation, LinkedIn Company Pages & ofcourse a Group Creation and group engagement.
Have a Nice Day.

Marketing has got a broader meaning, Marketing is creating the demand in the market and is more related with branding.
Being an online sales professional, i believe one should used the consumer base of the well known portal to spread the message (ex for c level audience we can take help of business/finance portal, same ways to cater to young audience we can look for social networking site, music portal etc.) At present times lots of organization is not getting expected return from banner advertisement, e-mail marketing or even through social networking site because they are unable to grab attention of the consumer base and time spent on the site is less.
So, our challenge now a days to increase interest in the product and time spent on site and i believe this can be well achieved through content integration process or through online sponsorship.
i would like to quote an example to make my point clear.
Suppose, IBM wants to promote their services related to "Cloud Computing" then instead of running plain banner advertisement or e-mail marketing techniques or taking social site one should promote the content related section on Cloud in one of the business news portal being sponsored by IBM.
This will help in making the readers of the portal aware about the cloud and placing banner & logo in that section will giver higher ROI than normal campaign.
So, to sum up i will suggest we have find innovative ways ( Like Online section sponsershi) to engage with consumer & create connect with the correct audience.
Then this can be considered as most effective marketing tool on internet.

Facebook is definitely a very effective one, especially if your brand is targeted towards consumers.

Social media platforms and the most effective tool, but they vary in importance based on your location, for example if you were in america , the best social media platform would be facebook, twitter and google+ if you were in kuwait it would be instagram, facebook, twitter.
it also depends on the type of the product you have !
