Home site links

I need to optimize a huge site. It has ca 300 pages with different articles on the same topic. Each page is optimized for its keywords. Some takes high position in Google, some not.
I want to put absolute links to pages with low position on others.
I wonder to know whether it can help to increase PageRank or it is just good for usability?

Sorry, you didn't make yourself totally clear.

From what I understand, you want to know whether having links on your homepage that go to your other website pages will increase your pagerank?

The simple answer is no. Pagerank is determined by how many inbound links from other sites your website has, not how many internal links you have.

Also, I don't recommend linking to all of your 300 pages on the homepage. Instead, use a HTML sitemap with links to all your internal pages and link to that.

From what I understand, the problem is that some articles don't rank as well as vovk would like them to and his plan is to place some deep links to them on this homepage.

This will make these articles rank higher, yes. However, each additional link on a page reduces the amount of link juice passed to the already existing links since all links share the total link juice available.
Therefore, if you add deep links to dozens of articles, several pages might drop in the SERPs which is probably not what you want.
Getting external links to the 'weak' articles would definitely be the best solution, but such links are of course not as easy to get.

Thanks a lot.
Where do you think would be better to place links to other pages in the body: on the top, in the middle or on the bottom?

Could you tell me where i can read ca link juice?

It is generally believed that links nearer the top of the page carry slightly more weight but - if you have text on your page and some of it relates to the page(s) you want to "boost" - it would probably be best to add the links within the text.

"Link Juice" is not really a generally used SEO term; we use it here but I haven't seen it used anywhere else (yet - lol).
What we mean by it is simply the "power" of the link (it's not just page rank but all the attributes of a link that carry weight forward to the linked page).

I'm not entirely sure I agree with the 2nd post above... If your home page has much higher PR than the pages you want to boost, a direct link from there will improve it's page rank... although - as Chris says - you only have so much PR to go around so if you "boost" some pages all others will suffer very slightly (depending how many links are currently on the page).

And don't forget - the home page isn't the only one which will deliver extra LJ... you could also boost those pages by linking to them from others (closer related = much better).

Thank you!
I put 3 - 5 links in the body.

I always employ a linking structure within the text that leads to related pages or articles. Any given article page will have links to 1-4 other pages with some same anchors, some varied anchors.

My homepage is saved for boost of certain pages, especially new ones. Currently, my HP is PR 5 with several PR 4 inner pages and a handful are PR 3. I've had some success getting newer pages ranked and continuing to rank with some targeting links from the HP and similar pages.

Again, as stated above, don't spread yourself too thin. The juice is finite.

How many links to other site's pages can i use without harm?

I disagree, if you structure your links correctly on a site you'd have no need for an HTML sitemap. Only sites that have bad link structures require HTML sitemaps, which is poor design in my opinion.

If you want to assist the search engines in indexing your site, all you need is XML sitemaps.

I disagree with you both ;-)
Having one html page containing links to ALL internal pages is not sensible if you have more than 100 internal pages. Some sites contain hundreds of thousands of pages.

Having a html sitemap for your visitors is not a bad thing as such, though. It's great if your site is easy to navigate so that few people need the sitemap, but having one does no harm at all and the occasional visitor might be glad to be able to get an overview of everything somewhere.
If you feel uncertain about the relevance in terms of SEO, you can always block that sitemap via the robots.txt and leave it solely to the visitors.

I see where both of you are coming from.

I agree that sometimes there is no need for a HTML sitemap if the internal linking structure is good (and the site is small).

For a big site however, it's easier for spiders to crawl your site if they can access the pages within a few clicks of each other. HTML sitemaps can help in this aspect of SEO.

But as Chris42 correctly said, a large site may have hundreds or thousands of pages. Splitting your sitemap into categorized sections, with each section having no more than 80-100 links, may be a solution.
