The marketplace is awash with people who 'claim' they can get your site right up their in the rankings. And I've seen some outrageous monthly fees for it (i.e £600 +) but nothing special delivered in terms of the SE rankings.
It's my understanding that Google for example employ as one of their primary criteria for ranking a website, is to measure the volume of other sites that link to it. The logic here is entirely rational. The more sites that link to it, the more popular that site must be .. so up the rankings it goes.
For your content, it's basically about 'helping' the SE spiders.
> Include the website name in the alt img text for all pictures.
> You need a few 'informative' phrases in the meta tags but again I've heard the SE's don't give the meta tags as much priority nowadays. Meta tags to use being Title, Author, Copyright and of course description.
> Search engines do value file names. If your images & media file names are more English than gobbledegook, this will help.
> Search engines still prefer plain text for their indexing.
I remember seeing a few years ago now, a photographic trick of the trade also employed by film/TV photographers, when shooting food for adverts.
There's a liquid which is poured over the prepared food which really brings out the colour of the food making it look so much more appetising for the photograph/commercial.
To all intense and purposes it makes the food inedible I think but is perfect for the task of making it look good for the picture/commercial. Maybe it's veg oil ?
Does anyone here know exactly what it is that they pour over the food ?
