Millions of people are searching the internet everyday, looking for something or someone to help them out.  If your business is not showing up in the search results, you are probably losing money and customers to your competitors.  Building a website that doesn’t rank high in the search engines is like opening a store in the middle of a major city and not advertising.  If you ever wondered why some businesses are doing great and others get zero business online, I can probably tell you it’s how they rank in the local search results. Every business online needs good Search Engine Optimization.
All you need to notice from this kind of articles is what I & most of the others newbies focusing on the SEO link-building. I have seen many bloggers spending time on different ways of SEO link building instead of providing the value to the content and its social promotions. You may call it ignoring the Google, but we all know that the Google bot doesn’t ignore anchored dofollow or nofollow backlinks to calculate your PageRank.
While backlinks are still an important factor used by search engines to determine content quality, linkless mentions are given more weight than ever before. This is partially due to the perception is that linkless mentions are more genuine, unlike black hat SEO techniques like paid links. Social media mentions are also playing an increasingly important role in evaluating website quality.
Alt text (alternative text), also known as "alt attributes" describe the appearance and function of an image on a page. Alt text uses: 1. Adding alternative text to photos is first and foremost a principle of web accessibility. Visually impaired users using screen readers will be read an alt attribute to better understand an on-page image. 2. Alt tags will be displayed in place of an image if an image file cannot be loaded. 3. Alt tags provide better image context/descriptions to search engine crawlers, helping them to index an image properly.

As an Internet marketing strategy, SEO considers how search engines work, the computer-programmed algorithms that dictate search engine behavior, what people search for, the actual search terms or keywords typed into search engines, and which search engines are preferred by their targeted audience. SEO is performed because a website will receive more visitors from a search engine the higher the website ranks in the search engine results page (SERP). These visitors can then be converted into customers.[4]
