SEO, or Search Engine Optimization, is regarded as one of the most popular (or even the most popular) is an online marketing tool. The purpose of SEO is to use different techniques all of which work to bring a website or webpage come amongst the top results in search engines like Google, Bing, etc. These techniques are easily divided into two:
On-page SEO basically includes the SEO techniques utilized directly on your webpage to get traffic and rank high in search engines. On-page SEO primarily includes keyword density and tags.
Keyword density refers to the percentage of keywords used on a page’s content. (If a keyword is used 20 times in a 1000-word page content, the keyword density is 2%).) Generally 1.5-2% is good keyword density – overdoing it doesn’t work.
Tags are relevant tags you add to your content – like short buttons that describe your content. It is important that tags should be relevant to the content or they don’t work. Tags can easily be used by finding tags relevant to your niche.
Off-page SEO mainly consists of backlinks. This is indirect SEO but still just as effective. Backlinks created to your keywords can help you get traffic from related sites and help with a good ranking in search engine results. But, just like tags, backlinks should be relevant to your content. The best backlinks are the sites with a high PR (Page Rank).
Both the types of SEO are equally important on their own and are also mutual in some ways. The right implementation of both the kinds in a moderate and relevant manner is the key to attaining the search engine result rank you want.
At the end of the day, SEO is not a single tool you use like a magic wand and suddenly your site is on top. SEO is rather a detailed and deliberate process that focuses on positioning your website in such a manner that with time, it comes to rank as a popular search engine result.
