Meta Tags

How many meta tags with key words I have to use on my site?5 or 6 or more then 14?
And My site description under site name should be the same with the meta tags or different?

Each page should use, title, description and keywords (NOTE - Before people say google ignore keywords META, yes, they do, some other search engines use them though)

Each should also be unique for that page

Title - that is the main one to get right, use your main page keywords but try and also make it look natural if you can

Description - has no ranking benefit but that is the 2 lines of text you use to sell the page to the searchers

Keywords - just bang about 7 or 8 in, will do you no harm but may benefit in other searches so you might as well ad them

Just remember to try and do it all natural and don't go spammy

Thanks Thebookiesoffers for your detailed answers

seach engines usually display the first 155-60 characters (including spaces) of the description meta.

Some tips that have helped SEO at my site. For example, a page name of /play-blackjack-quiz, I use the 3 keywords at the beginning of
title, description and keywords text. 1) Do not use the keyword 'blackjack' more than 3 times in any of the 3 sections to avoid keyword stuffing.
2) For this example, you have the benefit of searches that will capture both 'play blackjack' and 'blackjack quiz'. I usually use 3 keywords for each of the pages at the site for that reason.
3) no more than 5 keywords and they should/can be phrases.
4) I agree with the previous post in that the description is 'the big sell' for that page.
5) Be sure to use your 3 keywords within the text of the page. I try for once every 100-150 words, so the SE's index, rank and spread the word.
6) Participating in Social Media, specifically Twitter and FB is a traffic booster. I have started using HootSuite so that within any month, all or the majority of pages at the site are 'twitting'
My host provides a monthly report for all pages/keywords at the site and where they sit within the 3 major SEs. So, if that page appears in the first 30 searches of G, then that placement appears in blue while others appear as >30. I am pleased to say of the 160 pages at gamerisms, only 20 are not blue.
HTH

I will try to avoid to avoid keyword stuffing.I promote my site in social media.I know how important it is.
Thanks for the great advices.
