good points there but you did not cover lsi keyword techniques. Basically on page seo is also about using semantically related keywords in your page.

Adequate Keyword or keyphrase placement during On-page SEO is essential in order for the effect to be positive. Nonetheless we must not forget that the keywords must be placed within informative, quality and unique content. They should be included within well structured sentences.

Thanks for your advise.

And you also need to pay attention to keyword density if you are to have a good on page design.

Hi,
we should use following steps for effective use of keywords :

1. Always use keyword in title tags.
2. We should use keywords in the <meta name="description"> and <meta name="keyword">
3. We should put keywords in the body copy and alt tags.
4. Keywords contained in the URL or site address.

I would to add another 2 tips as below:
using your keywords in H1 tags;
using your target keywords and their variants as anchor text on-pagely and off-pagely.

Thanks,

Metatags are important in the past but Google has slowly reduced the importance making the SEO Weightage for onsite optimization at only 30% weightage. It's the offsite optimization that matters more right now.
