Hi, everybody!
Here's a recap of todays Roundtable -- Search Engine Spam. How exciting!
======================================
>> What is search engine 'spam'?
It's helpful to think of email spam. There is no exact definition of spam -- the government has regulated Unsolicited Commercial Email, but that doesn't cover all the unsolicited non-commercial email you get, and what about the stuff that you 'solicited' when you didn't notice the pre-selected 'yes' on a form somewhere? Email spam is basically any email you didn't want to get.
Search engine spam is similar: hard to define exactly, but basically whatever the search engines don't want to have showing up in their results. Sites that rank higher than they should because they've manipulated the factors that search engines use to assess quality. Of course, the very essence of SEO is getting sites to rank higher by manipulating the factors that search engines use to assess quality.
>> How is SEO different from spamming, then?
It's all in how you approach it. You can go to the mall by getting in your car and driving there (the "right way"), or you can get to the mall by getting in your car and driving across some median strips, over bushes and pedestrians, and through the playground at the elementary school (the "wrong way"). SEO and spamming both involve deliberately altering links and content to rank better in the search engines. The difference is between naming your pages "thermal wool sweater" and naming your pages "thermal wool sweater FREE generic viagara vogara vgara britney spears." SEO is creating your site with appropriate tags and content, designed to help search engines appropriately index and rank your pages. Spamming is anything that crosses that line.
We're obviously not trying to cross that line. But many websites do, accidentally. They just don't know the rules of the road, so to speak. There are a few tactics in particular that trip up the majority of websites that have issues with spam.
>> What should websites avoid?
1. Duplicate content and duplicate domains -- the most common problem is sites with lots of domains that have not been set up properly. Search engines see each domain as a separate site, decide it is a deliberate attempt to get lots of rankings for the same content, and penalize all of the sites. I found a cool page that lets you test this really easy:
http://www.webconfs.com/redirect-check.php
The primary domain (mainsite.com) should come up as "either not redirecting or not search engine friendly." That's because the primary domain is not redirecting. Then enter some of the other domains that the website has -- those should all come up as "search engine friendly." If they don't, they need to be fixed.
2. Hidden text -- the idea sounds great: write a good, user-friendly page, then add a ton of keyword-stuffed text at the bottom in the same color as the background! That way, users just see the nice text and search engines see all the great keywords. This actually used to work really well, but that was years ago. Now, it gets you kicked right out of the search engines. Hiding text with CSS, Javascript, Flash, or anything else will lead to the same. You want search engines and human visitors to see the same thing.
3. Cloaking -- a more extreme form of hiding text, cloaking involves using the server to detect search engine crawlers and showing them a different version of the site. The principle is the same, you want the search engines and humans to see the same thing. Even if you can fool every search engine crawler perfectly, the search engines have teams of humans who review sites, and your competitors are probably reporting you for spamming.
4. Linkfarming -- "Get 1000 quality links to your site for just $40!" The trick with this approach is that it sounds so good. Webmasters know you need links to rank well in Google. But those links need to be good, organic links. Sites that are selling links stand out like, uh... they stand out a lot. To search engines. So don't buy links in general, and especially don't buy links from sites or networks that are selling them wholesale.
>> Oops. 'My friend' did some of that on his website. How can he get back in the game?
Your friend needs to stop getting his SEO tips from 'how2makemoneyEZ.com,' first of all. If a site has been penalized for engaging in any of these practices, the first step is to reverse whatever bad thing was done. Domains can be configured with 301-redirects, hidden text removed, cloaking software uninstalled. In most cases, that will restore rankings that have been lowered. Linkfarms are harder to correct, and in a worst, worst case scenario it might be easier to buy a new domain name.
If the entire site was really removed from the search engines (confirm by doing a Google "site:domain.com" search), there's a longer road to follow. We can help sites move through that process, but it will cost a bit and take on the order of several months.
>> Bonus unrelated-but-great question of the day: How many links does a site need to rank well?
Do a search for the keyword you want to rank for. Pick a few of the sites that come up, then do a Google "link:oneofthesites.com" and see how many links that site has. Repeat. You'll have an edge on those sites if you optimize well, but in general you'll need to have comparable numbers of backward links to rank well.
