Current SEO Best Practices

In Module 3, we'll be discussing items that SEOs spend a great deal of time dealing with: SEO best practices, the algorithm updates that look for them and potential penalties for not adhering to them. By the end of this module, you'll be able to illustrate the concept of relevancy as it applies to search results, compare and contrast the functionality of search engine algorithm updates, and critically examine the ways in which webmasters attempt to circumvent these algorithms. You'll also be able to define important ranking factors used by modern search engines, and learn the necessary steps to avoid (or correct) any penalties applied by search engine algorithms.

Following up on our discussion with Panda, this lesson will focus on the Penguin

update and how it continued the tradition of updates that target spammy and

poor practice websites.

You'll be able to describe another set of violations

that are still being cracked down on today.

And we'll also touch on the idea of negative SEO, and

what you can do to avoid being targeted.

The next main algorithm update to discuss is the penguin algorithm.

As mentioned previously, links are very important to SEO, and

this has resulted in a lot of creative ways to earn back links to your site.

For a long time in SEO, backlinks were considered the Holy Grail, and many SEOs

and webmasters viewed link acquisition with an any-means-necessary approach.

While links from authoritative sites were certainly good,

people discovered that simply creating a large amount of links from low

quality sites was a very effective means of ranking for a particular key word.

For example in the past if I were going to rank for

a keyword like San Francisco Attorney.

All I would have to do is build a lot of links from many,

many sites, and use the anchor text, San Francisco Attorney in that link.

The penguin algorithm, which was released in 2012,

was created as a way to put a stop to many of the spammy link

building tactics that had been widely seen in the SEO industry.

Like Panda, Penguin is a filter, which means it is periodically re-ran.

Sites which have been penalized before will have a chance to escape.

While new sites may get caught in the web.

Penguin really focuses on sites that have a high amount of manipulative

link building practices in place.

Manipulative link practices are considered to be practices like link networks.

Link networks involved creating a set of sites that link to one another.

Sometimes these sites were hosted on different servers and

registered by different individuals.

This was done in an attempt to hide the link network from Google.

Another manipulative tactic was trading links.

Trading links involved your normal reciprocal link like,

hey if you link to my site I'll link to yours.

But also more difficult to find links, such as between people who own multiple

sites and only use a set of their sites to link to the other.

They did this to avoid what could easily be seen as reciprocal linking.

Another spare me tactic is comment spam,

this is still commonly seen even though it offers no volume.

This includes comments on news articles, blogs and other sites and

the the comment will often link back to their site.

Often times on blogs these articles will appear to flattering and

the comment author will talk about how much they love the topic And

how they can't wait to read more posts.

And by the way, view my blog and then they'll insert the link.

99% of the time those are actually automated comments created by a robot for

the purposes of SEO.

Unfortunately, newer blog owners often publish these,

believing they are real comments.

Other times the comment is more to the point, but

still attracts readers to click the link.

Like the comment might say hey, learn how I made 110k working from home and

then have a link to their site.

The next spammy tactic is aggressive exact match anchor text,

which we discussed briefly.

For example,

building a large number of links with the exact keyword you want to rank it for.

Google began penalizing this because it is obviously

not a natural occurrence of anchor text that would happen if

people were naturally linking to your site because they found it useful.

However, if your domain name contains the keywords used in the anchor text.

Let's say you have the domain name SanFranciscoAttorney.com,

and then a lot of links with the anchor text San Francisco

attorney are actually likely to be considered valid.

This of course depends on the rest of you're back link profile and

the types of sites you are running links from.

The penguin algorithm also targets paid links It can be difficult for

Google to determine if a link is paid or not.

However, there are certain things the algorithm checks for

when looking for a link.

For example,

if a link is in the side bar surrounded by ads, it is likely a paid link.

This also holds true for words surrounding the link.

So if they see words like, sponsors or sponsored.

Anywhere that is next to the link it's likely considered a paid link.

This also considers posts that contain reviews for an item or

businesses, as the user likely receives some sort of compensation for

that review whether or not it was monetary.

The filter will also look for things like links on low quality sites.

If the site is not relevant to your audience, for

example a link to an attorney on a site about flower arranging

then the link is likely either paid for or earned through manipulative means.

In the past you could temporarily escape these penalties by

redirecting your penalized site to a new domain.

But these redirects started redirecting the damage to the new site as well.

As Google has become more and more aware of spammy link building tactics,

they've been cutting down on these through updates to its web algorithm.

Link building has become more complex and more risky.

Some specific methods SEOs use to gain a large amount of back links in the past

were also discounted.

And some of the sites were even penalized.

Due to this, we advise not using specific types of link building

that you hear may have worked in the past.

These include spammy link building tactics like

acquiring links in various directories, creating free widgets

users can download that will contain an incretext link back to your site.

Some examples I have run across are free mortgage calculators,

what masters can add to their site as a useful tool.

But the tool will contain a link at the bottom

that says something like mortgage loans in the anchor text.

This is seen as spammy.

Another popular method of earning a large amount of back links

was creating free templates or themes for Blogger or WordPress.

The authors of these templates would put a link back to their site in the footer, or

sometimes just hidden within the code.

People would often create user accounts in a large number of forms and

add a link to their site in their signature or profile.

They will post once and then leave.

Links in, profiles, and signatures have been devalued since then so

it's not really worthwhile to go into that.

I suggest reading more about Google's quality guidelines regarding links at

Google Support Center in the link provided.

In addition, I've also provided a link to an article on search engine land with

a video at the bottom which discusses ways in which Google evaluates whether or

not a link is a paid link.

This is a very useful page to read and video to watch, so

take some time to check that out.

Once penguin rolled out, many sites were hit with a penalty and

lost a lot of traffic.

The rush to remove spamming links began, and

sites which were previously making money by charging for

links reversed their practices and began charging owners to remove the links.

Because of the impact seen, SEOs and

webmasters were concerned about the possibility of negative SEO.

In which an unethical SEO, creates a large amount of spammy back links to

a competitor's site, in an effort to get them penalized in search engines.

Due to many comments and requests on forums,

Google created a link disavow tool, which is now part of Google webmaster tools.

The Link Disavow tool allows owners to disavow spammy links

pointing to their site.

However, before using this tool it is recommended that you check the following.

First, make sure your site is actually penalized by Penguin before you

disavow links.

Unless you know that you have some very spammy links, And

you want to be proactive so you don't get penalized, don't just go and

remove all links because some might actually be beneficial to your site.

Next, make sure the links you disavow are actually poor quality links.

Where possible, try to remove the link yourself first.

Also, make sure you remove the WWW version of the link,

and any non-WWW versions of the link that may be point to your website.

That completes the video portion of this lesson.
