Rewrite FHG description to original
 

Hi:

I am having a worry on the default FHG description used as alt text on TGP to be seen as content duplication by google, so I spent a lot of time rewriting them to original text, but when I scan though some top ranking site, they are using the default description bu still able to be ranked in top position, so I would like to ask your opinion regarding this, whether is it necessary to rewrite the description to avoid duplication?

SEO is about doing as many things as you can to gain rank.
Not about doing one or the other or the other. :2 cents:

So you think it is not necessary?

will help, but as you saw, there are other variables involved

Yes, it is necessary. Everything is necessary. SEO is competitive.
You aren't racing against yourself. You are racing against everyone else. :2 cents:
