Our blog is often crawled but not all the pages are getting indexed. What's the issue here?

Can anybody provide me a good image re-sizer that can reduce or customize the resolution of any image given?

I am here trying to start my career as a PPC Manager. So, I was wondering does Google Adwords certificates helps? I mean to gain trust of the clients and all.

Recently we have added some affiliate products in our blog and forum. In forum we are using url shortener services to track the links. But in blog we don't want to use them because they will look too greedy in our site. Is there any other way to track those links?

I have 500 party tickets and I need to sale them within 2-3 weeks otherwise they will become invalid. How can I do that? The party is basically for college students. Should we try fb sponsored ads?

Is there anybody aware of any good plugin that can help me grow and send newsletters to my subscribers?

Its not that they readily accepts your guest posts. So, how do you guys do it?

I use Chrome for all purposes. Even though logging in to my gmail/adsense account. I generally use services like rhinorank for link building purposes. But since last year there are so many updates and people talking about getting penalized by google so much.

So, I am worried right now that will it be possible that google is watching every move I make. Last month I bought a link and since then my traffic has fallen around 15%.

How to increase the traffice for blog posting?
