When making up a blog using blogger I would like to know how you can add keywords to the blog so that the search engines , directories etc. can find it better & easier.

You put them in your content.

Yep, that's right. It's that simple.

Thanks chrishurst

Make good posts about the content you want indexed. Post some backlinks to your blog from other blogs that are of the same niche. Search Google for similar blogs and make comments on them with a link in your name back to your blog and soon you will be getting indexed regularly and also getting some search traffic.

For example if you have travels related blog so you will add Meta tag description or keywords on your blog html just like “World Travel Blog”. Furthermore, you also make keyword according to your blog but make sure your content is original and powerful then Google will crawl your site otherwise it will reject you.

Try to use keywords in Meta title, meta description and meta keywords.
In the content , you can try to use H1 size with keywords in headline .
Your content for keywords density should not more than 3 %.
Beside that you can optimize your site keywords with image Alt as well.

how you add meta tags in your site is also the same how will you add your meta tags in your blogs.

You have to do On-page optimization (i.e. title optimization, meta tags optimization, html tags, keywords optimization, link optimization, image optimization) and Off-page optimization (i.e. forum posting, search engine submission, directory submission, social bookmarking, article submission, press release promotion) to your blog.

For example if you have travels related blog so you will add Meta tag description or keywords on your blog html just like “World Travel Blog”. Furthermore, you also make keyword according to your blog but make sure your content is original and powerful then Google will crawl your site otherwise it will reject you.

When you create a new content in blogger then there is a tag field right? In that field you could insert your desired keywords (must be present in your article). Moreover, I think you can use <meta keywords> options in your post. I am not using blogger for so long but I am sure there are many blogs which provides very helpful information to bloggers about blog customization.

I think best is to have good title of your posts which is more important tag then meta keywords. Also there is tag option utilize that.

Keywords can be used in Title, content and and put them in tags.

"Meta Keywords Tag" has ABSOLUTELY NOTHING to do with any "keywords".

Sorry mate, Not sure. I can use "Meta keywords Tag" for specifying my content keywords. But above all, after panda update, keywords doesn't have any value in SERP, I have discussed about keywords value with some senior SEO experts and they all said same thing.

Wrong! The meta keywords elements has had no "value" for "ranking" and/or Search since ~2003.

You can add keywords to your meta tags, header, articles, "about" page, homepage... Everywhere .
Don't forget: make good posts about the content you want indexed. Post some backlinks to your blog from other blogs that are of the same niche.
