Most people know SEO as the combination of content, keywords and links that can boost a website’s search engine rankings, but it’s actually much more complex than that.

The search engines can change how they evaluate websites, web pages, content and links, which can result in the rank of a given page for a given keyword falling or rising without any changes by the website owner.
You spend hours scouring the web to find a handful of places where you can submit a link to your website….
You check the site content, to make sure it’s relevant to your niche – because the last thing that you want is to lose your search engine rankings. Why you possibly can lose it? Because Google thinks you’re getting links from spammy, off-topic sources….

You check the code to see whether or not links are marked “NoFollow” – because you know that nofollow links are practically worthless from a search engine perspective….You try to leave the keyword of your page in the link, because you want keyword-relevance in the anchor text to maximize the link’s value….And you try to say something that will get around blog-spam, directory-spam and forum-spam filters and moderation… Sound familiar? Yes, this a common problem for many businesses. A new website may take some time to get indexed by the search engines and to build up some backlinks*.

But there two other reasons why any site, new or established, might not show up readily in the search results pages: Backlinks from scammy websites that search engines see as really low quality or websites that exists solely for the purpose of trying to manipulate search engine rankings can get your business Web-site penalized or delisted altogether. Avoid this “techniques”. Search engine robots now smart enough. Create links to related content in your own Web-site. By building internal links to related content in your own Web-site you help search engines find your content and you associate specific keywords with your webpages by using those keywords as anchor text.**

* Backlinks are incoming links to a webpage. They help the search engines analyze important metrics like popularity, trust, and authority related to your website. It is believed that quality back-links from high authority sites can help you in achieving higher rankings in search engine result pages, also called SERPs.

**The anchor text, link label, link text, or link title is the visible, clickable text in a hyperlink. The words contained in the anchor text can determine the ranking that the page will receive by search engines. 

Whenever other websites or even your own content links back to your website, you increase the number of votes” that Google will consider when calculating your SEO potential and search engine results ranking.
