The halo effect is a cognitive bias that occurs when a person’s positive or negative traits seem to “spill over” from one area of ​​their personality to another in others’ perceptions of them. (As defined by Wikipedia).
How does the halo effect apply to SEO?

Everyone who cares about SEO should know that it takes longer to get a top ten ranking with Google, compared to MSN and Yahoo. Yahoo and MSN allow newer sites to rank high within weeks of their creation, yet Google makes a new site wait. Google does this so spammers can’t grab the top ranks through massive illegal link campaigns (like link farms).

The halo effect occurs when your site ranks first for a chosen keyword. After your site has started to rank as the top site for your chosen keyword, you can use the halo effect to your advantage and try to get search engines to rank your site in the top ten or even number one for multiple keywords. surrounding key.

Now that the SEO work has been carried out, your main keyword has already obtained its first position in the ranking. Therefore, search engines will also start to rank your site high on other relevant keywords around it, thus creating the halo effect.

Since your keyword ranks high, you don’t need to put in the same amount of effort for the other keywords. This may not make sense right away, but it’s essentially easier for you to rank your sites for similar and nearby keywords after you’ve achieved the top ranking position for your main keyword.
It is imperative that you first choose your primary keyword so that you can rank for it before attempting to rank for surrounding (secondary) keywords. Since the main keyword should be the most relevant to your site, you should start with that and keep in mind that SEO is an ongoing task, not a monthly task.

So take advantage of the trust you’ve built with search engines for your keywords and make sure you’re always on the lookout for similar keywords, which could help boost your SEO.
