While the use of keywords is useless for regular, or static webpages (the ones where content never changes), as Google and Yahoo removed the keyword tagging due to abuse, they are still important for many 2nd level (so to speak) search engines and very much so for blogs (or other websites, where content changes on regular bases). The question remains, how to find a perfect keyword?
Here are 6 inspiring ideas:
1) Title as a keyword. Don’t just copy past the title, but do use the main words of your title as your keywords. For both readers and webpages, titles serve as one of the most important ways of identifying the body of a content, therefore additional emphasis is important.
2) Search the body of your text. If you are writing a scientific paper or a book and you are looking for help with the structure for your content, many opinion leaders will tell you to write the body of the book first and the introduction, conclusion and the title second. This is because the introduction, conclusion and the title depend on the body and not the other way around. Therefore, if you are looking for a good keywords, don’t just take them from the title and the introduction. Also, see the main content. There are plenty of potential keywords there.
3) Use creativity. Spend 2-5m just thinking of any other ways you can think how you can say the same keywords. These will be indeed your new keywords.
4) Google the competition. Competitive or similar articles, by other authors, hold keywords that we sometimes don’t remember, or just could not think of, as other authors might be creative in different ways, or simply have different information, due to their specialization. These keywords could still be valid for you.
(Quick note here: why use step 3 if you can just get all ideas from step 4? Because in a long-term you want to rely mostly on yourself rather than on the others, otherwise I don’t think you would write in the first place.)
5) Find synonyms. When you got your keywords, from step 1 to 4, it could be a good idea to just google the rest. Write in a google, or other search engine “*keyword* synonyms” and see what you get.
6) Filter your keywords. If you go through steps 1 to 5 you will definitely exhaust all the options, but not all options are good for you. Even if someone is to find your content using a bad keyword, they will probably “bounce” (leave) immediately, informing search engines that you have a bad content than (or keywords), and search engines might decrease you in search priority.
