Keywords are the words that you want to be known for when customers do a search on the internet. This is a significant part of Search Engine Optimisation.
It is important to do your keyword research before you start generating web pages and posts, or you may end up being known for the wrong things. What do customers type into the search engines when they are looking for products and services like yours. Just remember that it may be different to the language that you use.
Used effectively search engines will see that your web pages and posts have these words. Search engines have smart algorithms so don’t go crazy and use the same word too much as the search engine may consider this to be word stuffing and penalise your site. What are the associated words or synonyms?
Once you have these words sorted you can the start using them effectively. So that the search engines understand what your page is about use the keywords once in the title, in the meta description, in the first paragraph, in subtitles and several times in the content.
