1. og Post Title
Most important Onpage factor which really plays a big role in deciding whether our blog posts will be doing well on search engines front is its title. We should make sure we are using targeted keywords or phrase towards the beginning of Title tag. We should not repeat the same keyword in title tag with the intension to get better rankings on Google, Yahoo and Bing. And we should keep limit Title Characters length to 65 Characters only with spaces.
2. Post Permalink Structure
Then it’s about going ahead with a search engine optimized URL structure. Again, you should aim at using targeted keywords towards the beginning of blog post URL. You should avoid using special characters, symbols, brackets, comma’s etc as part of your post URL. Most of the times you should be using alphabets and numeric from 0-9 in your URL structure and use dashes to differentiate two strings in URL structure. Make sure to follow a pretty permalink instead of random strings in your permalink.
3. Heading Tags
You should use heading tags like h2, h3 and h4 etc to highlight various headings, sub-headings and important points. Our Title tag is used as h1 tag at single post level in WordPress. So we don’t need to use any h1 tag in our blog post body section. Also, don’t repeat H2 or H3 tags too many times, as it is considered as negative SEO practice. Here is what Matt Cutts has to say about repetition of H1 or any other heading tags.
