Autosurf traffic exchanges:
For the sheer volume of traffic you need to boost your ranking in any search engine, you need to run your sites in autosurf traffic exchanges aka auto surf traffic exchange or no click surfing, and other similar venues - particularly high volume producers. Do not be swayed by marketing hype. Auto surf traffic exchanges provide the volume of traffic a person with little or no budget needs to push their sites up in the engines.
It is useful to actually own a traffic exchange or two! This way you get other people surfing and sending hits to your domains. If your budget won't accomodate a traffic exchange, then consider upgrading at some well managed autosurf traffic exchanges that allow for 24/7 surfing. You notice that this is the only area where I recommend you spend some money. If you are a person who has multiple computers, and can set them up to surf 24/7, you won't need to upgrade. Just ensure your computer is surfing for you day in and day out, week in and week out on many traffic exchanges. Again, those traffic exchanges need to be well maintained by the Admin and allow for the 24/7 surf.
Buy website traffic:
If you have a budget, you can buy traffic. Look for providers who can deliver bulk traffic in 30 days or less, and always test the provider before committing to a large volume order. Xtream Global is an example of a provider of bulk website traffic with guaranteed 30 day or less delivery on their bulk traffic packages.
Links:
There are several types of links: one-way (which Google seems to favor), reciprocol (you link to me, I link to you), and links in. Links in is widely used at Alexa. Links are considered a form of traffic.
Temporary vs semi-permanent and permanent links:
FFA venues are the most common form of temporary link systems. While widely bashed and trashed, if you look closely at all the negative press it is usually by someone wanting to sell you something else. Sell is the operative word. They are effective if used religiously and daily. I see no evidence to claims that the search engines penalize websites that list on ffa venues. While millions (or billions) of PEOPLE won't see your website, you can be assured the search engines will when they visit an ffa site for indexing. I often see posts to high traffic ffa boards like Traffic Wave, Adsaturation, Adresponse, Prospective FFA, and Multilinks find there way into mid - end of search engine listings.
Message boards and classified ad boards provide longer term links.
High profile venues like Craigs List used to appear reguarly in the Engines. Posts made to Voy boards often appear in mid to end listings.
The hands down best link situation is a permanent one. Put links to all your venues on your own websites for starters. Then, network with other webmasters for permanent links. Links can be done in a very discrete manner so as not to distract from your website. Basically, the search engines don't care where the link is place per se, just that it is.
Blogs and forums can be other productive mediums as well for links. In this respect, I am talking about permanent links or in articles. I am not talking about spam comments links. There are a lot of blog and forum blasters on the market. For the most part, those are usually spam vehicles.
Marketing pages:
Splash pages, squeeze pages, marketing pages, mini websites - whatever you want to call them - as long as they are hosted on a domain YOU own, you can't go wrong. Optimize them to reflect the businesses you are involved in. Publish on a regular basis. Market them in traffic exchanges - especially the auto surf traffic venues, the link boards, and network with like-minded individuals. Getting a link on a high profile website is fantastic, but don't rule out the lesser known vehicles. Go for quantity first, quality will follow.
