I think Jayesh's article site is listed in his signature. If you newbies ask what that is I'm going to ask Jayesh if his tutorial site has something for those new to forums...
Jayesh, if Vavk.com is the site you are talking about, it will help greatly to get those pages optimized. I'm looking at one of the article pages and the code has:
<.title>General Articles - Vavk.com<./title>
and that's for most of the pages I saw. If you just drop some page titles, description, and keywords tags in those pages and are different for each page, I think you will see a BIG difference. Right now Google shows 371 pages for your site, but all except 14 are classified as "
Supplemental Results".
I would take the article title, change it to make it more interesting if you can, but still have the same meaning and use this for the title tag. Maybe add a keyword from the article.
The take 2-3 sentences from the article, generally the first paragraph sets up the purpose of the article and sometimes you have to find another one. Use that, about 250 characters, for your description. Then use the keywords from the title and description for the keywords tag, separated by commas.
Do a few pages as you have time. if you do some every day you'll have them all optimized in 4-6 months.

To keep up with the work, consider adding a couple fields in your submission form so your authors can add them for you! You may have to edit them, but it should be less work the doing it all.
