Cheap in any sense of the word most of the time means inferior. Inferior in make and service, normally means no real time has gone into its making up. If one buys cheap the results obtained are normally cheap, that I mean in length of service.
If you are on a really tight budget then the use of cheap SEO “do it yourself” is better than nothing. There are packages available on the internet. At least you will obtain some exposure and receive web traffic. Do remember that SEO’s need maintenance and require updating continually.
There are some products that are better than others but you need to look carefully. Research on the web and see which is best suited to your product. Certain packages use techniques that are taboo in SEO practice. Be careful of packages that market your site too quickly or use key words that are not appropriate to your product. For instance there is Black Hat which Google is trying to wipe out. There are packages that you pay but don’t get the results that you’ve been promised. Constructing an SEO is like a building it can’t be done overnight, it’s got to be done correctly. It needs constant watch and maintenance. You’ve worked too hard to get this far so you don’t want to spoil it.
The internet is a body is changing almost daily and making use of a cheap SEO will probably see no quality service. You will probably just disappear into the deep fathoms of the internet. Go cheap and you end up cheap. That is not what you want is it?
Ideally, if possible at some stage later on you need to employ a professional SEO writer or agency. A high quality professional SEO writer would be more in touch with the product they’re writing for. Whereas an SEO package off the net is working “blind” and cannot tailor the most suitable SEO using the right key words. Remember presentation and keyword content is vital in helping to directing traffic to your site.
