As the industry is changing as rapidly as Google tweaks their algorithm, it is hard to decide what the most important factors are. The On-site and off-site are the two major factors in SEO which is necessary for every type of website. Normally, most of the webmasters starts with the on-site SEO, because your aim is to get your website recognize by Google. If they don’t, then how are you ever going to rank for a keyword?

The search engine spiders that crawl your E-commerce website will be looking at several different attributes on every page to determine where it needs to go and how relevant it is to specific searches done at Google search engine.

Another factor worth mentioning is a Keyword. What is a Keyword?

A keyword is basically an elaborate name for what people might search for when trying to find your E-commerce website. I am using a Bodhost.co.uk website as an example. People could search for "Web Hosting", but they might also search for "Cheap Web Hosting", "VPS Web Hosting" and "UK Web Hosting Service". All of these would be keywords, or probably more properly could be said to be key phrases.

However, they are generally all referred to simply as keywords. Note that almost all On-site SEO has to do with is placing high-quality keywords throughout your E-commerce website content where search engine robots, spiders, or software might be able to decide what your website is about.

6 On-Site SEO Factors That Can Influence Your SERP Ranking:

• The Title of the Page

• The keywords used in the text on your website

• The keywords are used in H1 Tags

• Keywords used in your domain name

• Keywords used in the URL of a webpage

• Meta Keywords

3 Major Off-Site SEO Factors That Can Improve Your Search Engine Ranking:

Backlinks to Your E-commerce Website

This is without a doubt one of the keys to having your website listed in the search engines results page for specific keywords. Google likes to look at what others are saying about your website to determine what it is about. For example, if someone is a huge fan of a UK Web Hosting, and you provide that service, they may link to your website with "UK Web Hosting" as the text that people would click on to get to your website. This text is called anchor text and Google will see that link as a simple "vote" for your website to appear higher than others for that keyword. In short, these are commonly referred to as backlinks.

Quality of the Websites linking to your Website

Those linking to your website should also have some form of importance. For example, there are many websites with loads of outgoing links to many websites. Google does not want to give these websites as much weight in their "vote" in comparison to a link from Bodhost’s official website or something along those lines.

The Age of Your E-commerce Website

The reason I listed this as an off-site related issue, because it really doesn’t fit in either category. This is a simple issue that the search engines will evaluate. This is not to say that it is the most important factor, but many older websites will naturally rank higher than new websites that have more backlinks.

I am not sure why this occurs, but many would say that it does. As compare to Google, Yahoo definitely puts more weight on this.
