SEO means “Search Engine Optimization”.
SEO helps us to promote our webpages to the top of the search results in Google predominantly.
There are many ways to do SEO, but it’s generally talked about in two forms:
a) On-page SEO / On-site SEO
b) Off-page SEO / Off-site SEO
a) On-page SEO :
On-page is what you control on your website/page itself, such as the header tags, meta-tags, alt tags for images, keyword density, having a few key pages like About, Privacy, Terms, Contact, etc.
But it only accounts for about 10% of the weight that Google considers in determining where your website will show up in the search results. Rank 1 on page 1 is obviously the best, taking in about 42% of the search volume according to many studies.
So if 100 ppl search for that term today, 42 of them will click the first website that shows up. Rank 2 gets about 12-13%, and it drops drastically from there. Anything on page 2 is worthless in terms of traffic, because it’s less than 1%.
b) Off-page SEO :
SEO refers to everything you do not on your website itself to promote your site. That means LINK-BUILDING. The more other sites link to your site, the higher your site will rank. However, if you do this in an unnatural way and too fast, this sends a red flag and you may get punished and dropped hundreds of rankings overnight. So you have to spread out your links and make it look organic.
Popular link building sources come from: -posting on blogs/forums with a link back to your site -social bookmarking pages on your website -Yahoo Answers -Craigslist (to help you get indexed quickly by the search engines) -article directory submission where you submit an article that has links back to your site (try Ezinearticles.com) -RSS feeds -web 2.0 sites such as Squidoo, WordPress, Zimbio, Blogger, and Hubpages -link exchanges with other people
Also keep in mind, that SEO is based around specific keywords, so you need to know how to choose the right keywords that get good traffic, high commercial intent, and low competition.
High traffic IS NOT ENOUGH. Low competition is NOT ENOUGH. You need to accomplish all of the rules.
