On page seo techniques and organic seo
Add your keyword to the H1 header:
The H1 tag simply signifies the main headline for any piece of content and it’s something that is especially relevant when it comes to Google figuring out what your page is about. So, be sure to add your main keyword in the main headline.
In WordPress, the page or post title you enter usually represents both the title-tag and the H1-tag, unless otherwise specified by you.
Add your keyword to an H2 header
H2 signifies a sub-header and also a slightly stronger signal about your page content than the normal paragraph content.
Sometimes you’ll see guides recommending you also add H3, H4, H5 etc. tags, all with your keyword inside. I have never seen this make a difference to rankings of a site and in terms of making your page relevant and useful to human readers, it’s counter-productive to have a whole series of sub-headings, all containing the same keyword. My advice: stick to H1 and H2 and you’ll be fine.
How often should you repeat your target keyword in the actual text on the page? Simple: more than once, but not more often than makes sense.
Don’t force a repetition of your main keyword again and again and try to shoehorn it into the opening and closing sentences, hoping that this will increase your rankings. It’s much more important to make the text interesting and readable for human visitors than trying to hit a certain percentage of how often the keyword is repeated.
Having bolded and italicized main keywords does seem to have a tiny influence as a rankings factor. With the emphasis being on tiny. What’s much more relevant is that bolding and italicizing text will make your content more pleasant to read, if used right.
Therefore, the rich-SEO advice is to use text decorations to make your content more engaging and more pleasant to read and if you include your main keyword in one of the bolded or italicized section, that’s a nice bonus. Once again, though, don’t force it just for the sake of SEO.
The image alt-tag is an alternative description for your image, which displays in case the image cannot be loaded. Add a descriptive alt-tag to all of your images and include the pages main keyword in this description. Also add your keyword to the images filename before you upload it. In WordPress, you can specify the alt-text for each image in a simple text field.
