Blog spam is normally used by those in competive industries with troubel getting links. This includes adult, casino, and phamacy sites. Recently I've been getting lots of "horny goat weed" spam. I don't even know what that is and I wonder how profitable that niche is. If it's quite profitable we bloggers will be seeing more horny goat weed spam...
ESL Ad, my AWS full store now has 8,230 pages indexed by Google. That came from 2 PR 6 links from subpages of ESL go, some directory listings at Jtrotta.com including deep links and few blog links (like from this blog).
Exercise Plaza now has 72 pages indexed by Google. This did not happen as quickly as I expected but it was still less than 72 hours since I added the deep links and less than 6 days since the site launched and acquired its first link.
Considering how difficult it was to get my online advertising blog indexed with directory listings mostly to the homepage, I think it's clear that directory listing should point no only at the home page but all deep into the site's content if you want to get indexed quickly. My directory submission service may be useful there.
So my handful of directory listings has not been enough to get Exercise Plaza indexed in the past 3 days. I've added a few deep links from my health directory. Also added two more deep links from PR 3 pages at jtrotta.com.
If the site is indexed soon after these links (and they are not especially powerful) I'll have enough anecdotal evidence to work under the assumption that deep links get new sites indexed by Google faster than links to the home page.
Over the past few months I've shared many of my personal experiences with the Digital Point Link Coop. Here, I'd like to consolidate my information to help people make an informed decision, especially important now that there are other viable alternatives to the ad coop.
How it works: You set up the ad coop on your site. The set up process depends on the type of site you have but always includes a .php file with the coop code, a .txt for storing ads, and an include. The set up instructions are easy to follow for message boards and blogs.
Once the coop is installed on your site, you will get a weight based on your PR and number of pages indexed. You may submit ads, which will appear across the network. The number of times your ads show depends on your weight.
How well it works: It works very well for Yahoo! and MSN but not as well for Google. Because ads rotate to different sites in the network, links do not age. There is strong evidence to suggest that Google values older links and this explains why the coop is not as effective for Google as it is for Yahoo! and MSN.
In my case it works so well for Yahoo that I can not imagine life without coop. I have gone from almost no Yahoo! traffic to over 1,000 people a day for one of my sites (tw different keyword phrases).
Where it works: I have coop installed on blogs, message boards and AWS sites. AWS installation is more difficult but if you're having an AWS store built you might as well find a designer who can handle a coop installation.
The alternatives: Link Vault, which generates less link churn and therefore may have a greater effect on Google results has been getting a lot of attention recently. I will report back when I have more information on Link Vault and some examples of how well it works.
A new SEO experiment about how to get Google to index a new site quickly. I've linked to my new site, www.exerciseplaza.com from two pages of www.jtrotta.com (both are new pages but will likely be PR3), a PR 3 page in GoGuides.org, and a PR 4 page in Seoma. All links go to the homepage.
Currently zero pages indexed. Let's see what happens.
Search engines will not find your great content unless you help them. When I started my ESL site it was the second best free English learning resource available. I got around 10-20 visits a day through word of mouth.
Now (2 years later) I'm getting 1,000 people a day. The content is still good, but it hasn't been updated in a year. The search engines don't care. All they know is that I have more incoming links now.
Regarding on page SEO, it's only worthwhile for non-competitive keyword combos. My advice is to forget about it and focus on good content for humans and links for search engines.
I recently had the seo hack (but without mod rewrite) installed on my forums. The first thing I noticed that my grammar forum went from nearly 3000 pages indexed to under 200. However, several forum owners were reporting similar issues.
We're back to 2,200 now. Interestingly, some of the indexed pages have old cache dates. I imagaine that some of these (like the profiles) will eventually be dropped from the index since we no longer have incoming links to the profiles.
The last time I wrote about my ESL Ad AWS store it had 47 pages indexed on April 30. Now it has 518 pages indexed. This is probably due to two PR 6 links (which I mentioned in the April 30 post).
However, I also changed the header navigation so this experiment doesn't really tell us anything (at least not about the importance of the two PR 6 links alone). It will be recreated without the navigation changes. Once my new AWS site, exerciseplaza.com is set up - I'll give it a couple PR 6 links and see what happens.
