Except Guerilla marketing, all other marketing methods can be use online and
not only though SEO or for ranking a website, but also driving a number of
traffic to it.

Thank for this comparaison, i don't Know guerilla marketing.

For one of my company, i prefere the email marketing, after that, depend of
the activity i think !

Every business aims at higher ranking in search engines and flow of traffic.
Various ways to reach there are these tactics like viral marketing, email
marketing and guerilla marketing.
As the name suggests, email marketing is promoting your services and products
through emails. Viral marketing is specially word of mouth type and guerilla
marketing is analysing what your competitors do and doing the same way.

Well, the usual marketing strategies used before are still useful as it is
today. But not all business can be involved in the online business industry.

Only chosen business types can actually succeed and be involved in this type
of online marketing strategy.

Knowing whether your business will succeed or be valuable online or not is a
factor that an individual must consider before getting his/her business
online. Investing on it is not an easy one, and it requires a considerable
amount of money to use for investment on it.

Thanks,

Personally, i think the viral marketing is the best.nowadays People have
become callous and numb to advertisements but they still care about what
their friend is using or is liking.

You can try virurl, acoolme, mylikes. They really can bring traffic to your
site.

Guerilla Marketing is an unconventional marketing tactic often used by small
businesses.

Email marketing is directly marketing a commercial message to a group of
people using electronic mail (email).

On the Internet, viral marketing is any marketing technique that induces Web
sites or users to pass on a marketing message to other sites or users,
creating a potentially exponential growth in the message's visibility and
effect.

Buzz marketing is a viral marketing technique that attempts to make each
encounter with a consumer appear to be a unique, spontaneous personal
exchange of information instead of a calculated marketing pitch choreographed
by a professional advertiser.
