Well in Internet land there is literally thousands if not millions of websites for
learning Spanish out there all offering a wide range of services and products and unless you really know what you're looking for it can be a minefield to say the least.
In fact even if you know what you're looking for the choice of websites to learn spanish can be overwhelming and you can spend much more time on the internet than you really want to. My advice is quite simple really and that is to manage your time by actually working out what you want from your website. A bit of simple research might save you a lot of hours later on but what type of research?
For example if you want to study Spanish which would be the number one reason to visit a learn Spanish website why not visit the portal type blogs and websites where people make there recommendations of various products but more importantly give your there reasons as to why they are recommending them. From this you can then make a shortlist of learn Spanish websites that are likely to have what your are looking for thus saving you a lot of time and you getting what you actually want.
The alternative is pretty horrendous literally spending hours and hours searching the various sites and possibly ending up with the wrong product. The internet is based on the principal that knowledge is power. So as long as you're getting to the right places without misinformation then arm yourself with that power and save yourself time and money.
So in conclusion its pretty simple to get the best out of websites for learning Spanish do your research find people or blogs you can trust make a shortlist and then go check it out and make your choice.
