Encourage incoming links. Google prioritises sites that have a lot of incoming links, especially from other trustworthy sites. Encourage clients, friends, family members, partners, suppliers, industry mavens and friendly fellow bloggers to link to your site. The more incoming links you have the higher your site will rank. But beware SEO snake oil salesmen who try to trick Google with spammy links from low-reputation sites. Some links can actually damage your SEO.
Pay Per Click (PPC) advertising is the most common form of paid SEM. PPC ads are the ones you see at the top of your Google search with the word “ad” written discreetly next to the link. Search engines such as Google sell keywords to the highest bidder. One of the nice things about this form of advertising is that – as the name suggests – you only pay for the ad when someone actually clicks on it.
Search engine marketing is the practice of marketing a business using paid advertisements that appear on search engine results pages (or SERPs). Advertisers bid on keywords that users of services such as Google and Bing might enter when looking for certain products or services, which gives the advertiser the opportunity for their ads to appear alongside results for those search queries.
Well, yes and no. Sure, you can get hit with an algorithm change or penalty that destroys all your traffic. However, if you have good people who know what they are doing, this is not likely to happen, and if it does, it is easy (in most cases) to get your visits back. Panda and Penguin are another story, but if you get hit by those it is typically not accidental.
