How to research keywords
Three methods:
Google Search Console. Actual search keywords and phrases that are easy to find. Only shows what you're ranking for already, not what you should be ranking for.
Google Ads. Actual search keywords and phrases that are easy to find. Some keywords may be related, but not relevant.
Word clouds. Gives a lot of words to use. Takes time and effort to make, but may put too much importance on below-average quality sources.
How to use keywords
Chain your keywords from the SERP to your page: Meta title – Meta description – H1 – (H2) – page body.
Put the keywords at the start of the sentence.
Don't stuff keywords into the page.
How to outsource copywriting
If you have completed your keyword research but you do not have the time or ability to write the content for using the keywords, freelance writers may be able to assist you. Since the dawn of quality content as an SEO essential, freelancers have been providing an easy way of churning out words. The quality - and price - of the writing varies, but some tremendous writers are available on task outsourcing websites if you have the budget.
The key to getting your money's worth from your freelance team is making sure they are adequately prepared. Prepare a folder with all of the necessary documents and instructions for your freelance writer. At a basic level, this may just be a word document with target keywords, a word count, and a set of basic SEO guidelines for keyword use (like those in the previous section). For more sophisticate jobs you may need to include a list of keywords ordered by priority, a series of H2 and H3 headings, a set of reference URLs, and target audience descriptions.
Conclusion
In EC Center we always try to explain to our customers that in SEM, YOU tell Google the Keywords (because you are paying Google money), BUT in SEO, Google tells YOU the Keywords. So in SEO you "reap" what you "sow", you will only get traffic for keywords that Google finds in your content.
