SEO goes a lot further than just on page optimization, changing meta tags, title tags and alt tags, there’s a number of other things we need to do, most of can be done by yourself when all set up correctly.
Adding keyword/key phrase rich content to the site regularly, this is best done through adding a blog section to your site, some like to call it a news section (usually more corporate businesses). Next you ask, but which blog there’s so many? I always recommend WordPress to my clients as I find it gives the best results for SEO, it also has an SEO plug in that lets you optimize each article yourself. Not only does a blog add content and keep it updated regularly (which Google likes) its used to drive traffic to the site which I will go through next.
Google ranking: Google ranks your site by how many visitors your site gets, how long visitors spend on a website, where these visitors come from and so on, the higher the page ranking your site has the more likely it is to rank higher in Google, as well as this your site page ranking is also based on how old the domain is, the older the domain the more Google likes your site basically.
Driving traffic to your site: The best way to do this is, firstly add a blog to your site and blog about stuff your potential customers will be interested in reading, secondly get as many twitter / Facebook followers as you possibly can, I find the best way to do this is to follow users who follow your competition, this way you know your following people (potential customers) who are interested in what you do and they usually follow you in return.
How Twitter works: after publishing your blog article, send a twitter update (Tweet) out for example I might send, ‘how to market yourself online’ with a link to the article on my site. This achieves a few things, firstly you have gained a visitor to your site; secondly, you’ve given a potential customer some free useful information which is always a plus in their minds. Further than this, any Twitter followers that see your tweet and finds it useful will re-tweet this, then their followers see it and re-tweet, so on and so on. Anyone interested in your article will click the link taking them to your site. This also helps gather followers as they usually add you on Twitter gaining an extra follower / potential customer, I’ve been doing it a few months and have gone from 56 followers to nearly 600 followers and I haven’t publish half as many articles as I should have done as you’ll be able to see (my last one being in January). To keep building followers you need to tweet quite regularly I’d recommend at least once a day or every couple of days, but try to always tweet about stuff your followers will be interested in or people will stop following you. I found out the hard way talking to Twitter friend about general stuff, NOT a good idea I find you lose followers instantly, the odd mention is ok but don’t flood the place with comments about your weekends antics!
Another way to drive traffic to the site is through email marketing, firstly you have a data capture on your home page something like newsletter sign up, although I find this quite dated, keep it simple for example I might have, ‘Receive free information about effective user friendly design methods, sign up here,’ You then have an html email that goes out to your database of email addresses every month, I wouldn’t over do it with HTML emails, one useful email full of quality information I find works best. Links on the email links back to your site increasing overall traffic to your site.
Link Building is the final straw for SEO, this is external links from other sites to your site, basically just as many links as possible form, to your site, you can do this yourself through comments on blogs and signing up for as many free business directories as possible, this can be very time consuming not to mention boring but you can also pay companies to do this for you it’s up to you.
Anyway I hope you’ve enjoyed this article and its shed some light on how Twitter and blogs help with your SEO, as you may have noticed I’m a designer not a copy writer so please excuse any bad grammar
